The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual. 3 SIENNA (EM0530U) B HOW TO USE THIS MANUAL * The system shown here is an EXAMPLE ONLY.

[M] : Page No. [N] : Indicates the ignition key position(s) when the power is supplied to the fuse(s). 5 SIENNA (EM0530U) B HOW TO USE THIS MANUAL [O] System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

2 of the front wiper motor through the WIP fuse. The current flows to TERMINAL 1 of the front washer motor through the WSH fuse. 1. Low Speed Position With the front wiper and washer SW turned to LO position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to run at low speed. 2. High Speed Position With the front wiper and washer SW turned to HI position, the current flows from TERMINAL 17 of the wiper and washer SW to TERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the front wiper motor to run at high speed. 3. INT Position With the wiper and washer SW turned to INT position, the wiper relay operates and current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This activates the intermittent circuit and the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper operates. Intermittent operation is controlled by a condenser charge and discharge function in the relay. 4. Washer Interlocking Operation With the front wiper and washer SW pulled to washer position (Washer SW ON position), the current flows from the WSH fuse to TERMINAL 1 of the front washer motor to TERMINAL 2 to TERMINAL 11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the front washer motor to run and the window washer to spray. Simultaneously, current flows from the WIP fuse to TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND, causing the wiper to function. : Parts Location Code See Page Code See Page C12 39 J3 A 40 F3 36 J4 B 40 F5 36 J15 40 : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) 1C 31 Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 1H 30 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) : Ground Points Code See Page Ground Points Location EA 50 Front Side of the Right Fender Apron IE 52 Left Kick Panel 168 SIENNA (EM0530U) Code J27 See Page 40 Memo 169 SIENNA (EM0530U) Rear Wiper and Washer C12 Combination SW (IG) 20A WSH 20 1C 2 13 A 12 A 29 B 28 B J13(A), J14(B) Junction Connector 1 W–B L–O A L–R L–W B B 2 3 BE1 16 BG1 7 BG1 J37 Junction Connector L–R 4 BE1 L–R L–R L–O 18 L–O 12 L–O L 8 L–R 1 BG1 2 L–O L–W L 15 B B A J 3(A), J 4(B) Junction Connector 32 A A 13 L–O L–W 2 10 L–W J46 Junction Connector 12 L–O M HI L–W 1 LO Washer+ON R1 Rear Washer Motor L–O 2 1P OFF D13 Diode (Rear Wiper) 15A RR WIP Washer Rear Washer SW Rear Wiper SW (IG) 3 2 LS C1 W–B 1 +B M Rear Wiper Motor Rear Wiper Relay R33 Rear Wiper Motor and Relay 170 SIENNA (EM0530U) IE System Outline When the ignition SW is turned on, the current flows from the WSH fuse to rear washer motor TERMINAL 1, and the current flows from the RR WIP fuse to rear wiper motor and relay TERMINAL 1 respectively. 1. Rear Wiper Normal Operation When the ignition SW is turned on, and the rear wiper and washer SW is turned to HI position, the current flows from the rear wiper motor and relay TERMINAL 1 to TERMINAL 3 to the rear wiper and washer SW TERMINAL 10 to TERMINAL 2 to GROUND, and turns on the rear wiper relay. As a result, the current flows from the rear wiper motor and relay TERMINAL 1 to the rear wiper motor to GROUND, and operates the rear wiper. 2. Rear Wiper Intermittent Operation When the ignition SW is turned on and the rear wiper and washer SW is turned to LO position, current to TERMINAL 1 of the rear wiper motor and relay flows to TERMINAL 2 of the rear wiper motor and relay to TERMINAL 13 of the rear wiper and washer SW to TERMINAL 2 to GROUND. This causes the motor to operate (The point changes) and the intermittent circuit of the relay operates. Intermittent operation of the circuit is controlled by the charging and discharging of the condenser installed inside the relay. 3. Washer Operation With the ignition SW turned on and the rear wiper and washer SW turned to ON position, when the washer is turned ON (To wiper HI side), current to TERMINAL 1 of the rear washer motor flows to TERMINAL 2 of the motor to TERMINAL 12 of the rear wiper and washer SW to TERMINAL 2 to GROUND so that the rear washer motor rotates and the window washer emits water. With the ignition SW turned on and the rear wiper and washer SW turned to OFF position, when the washer is turned ON (To wiper OFF side), current flows as above so that the rear washer motor rotates and the window washer emits water as well as the wiper operates. : Parts Location Code See Page C12 D13 Code 39 J13 39 J14 See Page Code See Page A 40 R1 37 B 40 R33 45 J3 A 40 J37 43 J4 B 40 J46 40 :

The Main Opening–and–Closing Operations (1) By pushing the remote control SW, the automatic opening and closing of the back door can be carried out. (2) By pushing the operation SW formed in overhead console, the automatic opening and closing of the back door can be carried out. (3) Assistant operation: By pulling the back door from full open position, the automatic closing of the back door can be carried out. ∗ The automatic opening (Closing) operation of the back door is possible only when the power back door main SW in the instrument panel of driver’s seat part in ON. 2. Consideration of Safety (1) The power back door touch sensor is adopted. If the power back door touch sensor which is arranged on the end of the back door detect something pinching or obstacle during the automatic operation, the door will be reversed in full open direction. (2) If something pinching or obstacle in the back door is detected by speed change of the move of the back door during the automatic operation, the door will be reversed in opposite direction of the advance direction. (3) If the remote control SW or the satellite SW is operated for someone feel danger, etc. during the automatic operation, the door will be reversed in opposite direction of the advance direction. :

Input Signals (1) Water temp. signal circuit The water temp. sensor detects the engine coolant temp. and has a built–in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine control module as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the mass air flow meter and detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine control module. (3) Oxygen sensor signal circuit The oxygen density in the exhaust emission is detected and is input as a control signal from the heated oxygen sensors to TERMINALS OX1B and OX2B of the engine control module. (4) RPM signal circuit Camshaft position is detected by the VVT sensor (Bank 1 exhaust side, bank 1 intake side, bank 2 exhaust side and back 2 intake side), and their signals are input to TERMINALS EV1+, EV2+, VV1+ and VV2+ of the engine control module as control signals. Also, the engine RPM is detected by the crankshaft position sensor installed in the cylinder block and the signal is input into TERMINAL NE+ of the engine control module as a control signal. (5) Throttle position sensor signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINALS VTA1 and VTA2 of the engine control module. (6) Vehicle speed circuit The vehicle speed sensor detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine control module via the combination meter, from TERMINAL SP1 of the skid control ECU with actuator. (7) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine control module. When the power SW is pushed on, the voltage for engine control module start–up power supply is applied to TERMINAL +B and +B2 of engine control module via EFI relay. (8) Intake air volume signal circuit The intake air volume is detected by the mass air flow meter, and is input as a control signal to TERMINAL VG of the engine control module. (9) Stop lamp SW signal circuit The stop lamp SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of the engine control module as a control signal. (10) Starter signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is detected, and is input into TERMINAL STA of the engine control module as a control signal. (11) Engine knock signal circuit Engine knocking is detected by the knock control sensors, and is input into TERMINALS KNK1 and KNK2 of the engine control module as a control signal. (12) Air fuel ratio signal circuit The air fuel ratio is detected and input as a control signal into TERMINALS A1A+, A2A+ of the engine control module. 86 SIENNA (EM0530U) 2. Control System ∗ SFI system The SFI system monitors the engine condition through the signals input from each sensors to the engine control module. The control signal is sent to the engine control module TERMINALS #10, #20, #30, #40, #50 and #60 to operate the injector (Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals input from each sensors to the engine control module. The best ignition timing is decided according to this data and the data memorized in the engine control module. The control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5 and IGT6, and these signals control the igniter to provide the best ignition timing. ∗ Heated oxygen sensor heater control system The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust emission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine control module evaluates the signals from each sensors, and outputs current to TERMINALS HT1B or HT2B to control the heater. ∗ Air fuel ratio sensor heater control system The air fuel ratio sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust emission is low), and warms up the air fuel ratio sensor to improve detection performance of the sensor. The engine control module evaluates the signals from each sensor, current is output to TERMINALS HA1A and HA2A, controlling the heater. ∗ ACIS The ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed in accordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in all ranges from low to high speeds. ∗ ETCS–i The ETCS–i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, under all driving conditions. ∗ Dual VVT–i Dual VVT–i controls the intake and exhaust valve timing to the most appropriate levels in accordance with the engine conditions. 3. Diagnosis System When there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the memory. The malfunctioning system can be found by reading the code displayed on the check engine indicator lamp. 4. Fail–Safe System When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control based on that system. In that case, the fail–safe system either controls the system using the data (Standard values) recorded in the engine control module memory, or else stops the engine. 87 SIENNA (EM0530U) Engine

The electronically controlled transmission, however, electrically controls the line pressure, throttle pressure, lock–up pressure and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls gear shift timing and lock–up timing in response to the vehicle’s driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off. 1. Gear Shift Operation When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine control module from the engine coolant temp. sensor and the vehicle speed signal is input to TERMINAL SPD of the engine control module. At the same time, the throttle valve opening signal from the throttle position sensor is input to TERMINALS VTA1 and VTA2 of the engine control module as throttle angle signal. Based on these signals, the engine control module selects the best shift position for the driving conditions and sends current to the electronically controlled transmission solenoid. 2. Lock–Up Operation When each signal makes engine control module recognize that LOCK–UP condition is satisfied, the current flows from engine control module TERMINAL DSL to electronically controlled transmission solenoid TERMINAL 10. At the same time, the current flows engine control module TERMINAL SL1+ to electronically controlled transmission solenoid TERMINAL 6 and from TERMINAL 13 to engine control module TERMINAL SL1–. This works LOCK–UP solenoid to perform LOCK–UP operation. 3. Stop Light SW Circuit If the brake pedal is depressed (Stop light SW on) when driving in lock–up condition, a signal is input to TERMINAL STP of the engine control module. The engine control module operates and cuts the current to the solenoid to release lock–up. : Parts Location Code A9 See Page Code See Page Code See Page A 38 E12 36 J21 40 B 38 F16 39 J47 40 38 G4 39

Cruise Check BEAN IC Speedometer IG+ System Outline The dynamic laser cruise control system allows the vehicle to travel at a constant speed. Also according to the signals from the laser sensor and steering sensor, the system controls the vehicle to travel maintaining a certain following distance in proportion to the speed of the vehicle ahead. 1. Setting During driving under the ON–OFF SW ON condition (The cruise indicator is lit), when the – SET SW is operated at the vehicle speed higher than the lower limit vehicle speed for setting, the vehicle speed at the time the SW is turned OFF is set as a set speed and the control starts. However, when the SW is operated at the speed higher than the higher limit vehicle speed for setting, the higher limit vehicle speed is set as a set speed and the control starts. During driving under the ON–OFF SW ON condition (The cruise indicator is lit), when the – SET SW is operated at a vehicle speed between the lower limit vehicle speed for setting and the high speed limit, the vehicle speed at the time the SW is turned OFF is set as a set speed and the control starts. 2. Changing Method of the Set Speed (1) How to lower the set speed ∗ During driving under cruise control, when the – SET SW is momentarily operated (For approximately 0.6 seconds), the set speed decreases in increments of 5 km/h per SW operation. When the – SET SW is kept ON, the set speed decreases continuously in increments of 5 km/h until the SW is turned off. However, if the set speed reaches the lower limit vehicle speed for setting, the set speed cannot be decreased any further. When the set speed is changed, the vehicle decelerates to that speed (In some cases, the vehicle may accelerate). ∗ If the – SET SW is turned from ON to OFF when the vehicle speed exceeds the higher limit vehicle speed for setting while the vehicle runs down a slope, the higher limit vehicle speed is stored in the memory as the set speed to control. (2) How to raise the set speed ∗ During driving under cruse control, when the + RES SW is momentarily operated (Approximately for 0.6 seconds), the set speed increases in increments of 5 km/h per SW operation. When the SW is kept ON, the set speed increases continuously in increments of 5 km/h until the SW is turned off. However, if the set speed reaches the higher limit vehicle speed for setting, the set speed cannot be increased any further. When the set speed is changed, the vehicle accelerates to that speed (In some cases, the vehicle may decelerate). NOTE: The vehicle speed at the time the – SET SW was turned OFF is not reset if the – SET SW is turned ON when the vehicle is accelerated by depressing the accelerator pedal. In such cases, the set speed decreases by 5 km/h as described above. (1) Deceleration ∗ During driving under cruise control, turning ON the – SET SW decelerates the vehicle while the SW is ON. The vehicle speed is controlled using the vehicle speed at the time the SW is turned OFF as a set speed. If the – SET SW is turned from ON to OFF when the vehicle speed exceeds the high speed limit while the vehicle runs down a slope, the vehicle is controlled with the high speed limit as a set speed. ∗ When the – SET SW is momentarily operated (For approximately 0.6 seconds), the set speed decreases in increments of 1.6 km/h per SW operation. However, if the SW is operated when the set speed differs from the actual vehicle speed by 5 km/h or more, the vehicle is controlled using the vehicle speed at the time the SW is turned OFF as a set speed. (2) Acceleration ∗ During driving under cruise control, turning ON the + RES SW accelerates the vehicle while the SW is ON. The vehicle speed is controlled using the vehicle speed at the time the SW is turned OFF as a set speed. When the vehicle speed exceeds the high speed limit during the + RES SW operation, the vehicle is controlled with the high speed limit until the SW operation is finished. After the SW operation, the vehicle is controlled with the high speed limit as a set speed. ∗ When the + RES SW is momentarily operated (For approximately 0.6 seconds), the set speed increases in increments of 1.6 km/h per SW operation. However, if the SW is operated when the set speed differs from the actual vehicle speed by 5 km/h or more, the set speed is not changed. ∗ The vehicle speed at the time the – SET SW was turned OFF is reset when the vehicle is accelerated by depressing the accelerator pedal and the – SET SW is turned ON. However, when the SW is operated at the speed higher than the high limit speed, the SW operation is not effective. 253 SIENNA (EM0530U) Dynamic Laser Cruise Control 3. The Lower Limit Vehicle Speed for Setting ∗ It means the lower limit speed in the settable range and is set at approximately 45 km/h. It is discriminated from the low limit speed. ∗ A set speed is not stored in the memory when the vehicle runs at the lower limit vehicle speed for setting or slower. 4. The Low Speed Limit It means the lower limit speed in the controllable range and is set at 40 km/h. When the vehicle speed decreases below 40 km/h while the vehicle runs under cruise control, cruise control is automatically canceled. Vehicle–to–vehicle distance control mode and constant speed control mode store the set speed in the memory at this time. 5. The Higher Limit Vehicle Speed for Laser Cruise Control Setting It means the higher limit speed in the radar cruise control settable range and is set at approximately 135 km/h. 6. The High Speed Limit (Only in Constant Speed Control Mode) It means the higher limit speed in constant speed control mode under cruise control and is set at approximately 200 km/h. 7. Resume ∗ If cruise control is canceled at the vehicle speed higher than the low speed limit, turning ON the + RES SW accelerates the vehicle to the set speed at the time cruise control is canceled. ∗ Under the follow–up control, when the driver or vehicle ahead changes lanes and the road ahead is clear, the vehicle accelerates automatically and gradually to a set speed. When the + RES SW is turned ON at this time, the vehicle speed can increase promptly (Only in vehicle–to–vehicle distance control mode). 8. Shift–Down Control When the vehicle climbs a hill while running under cruise control, the gear may be shifted down by the A/T control. When the hill climb is judged to have finished, based on the throttle opening information, the gear is shifted up after a set time. 9. Cancel Cruise control is canceled if the following signals are input under cruise control (Set speed is not erased).

constant vehicle speed controller which controls the opening angle of the engine throttle valve by the SW, and allows driving at a constant speed without depressing the accelerator pedal. Set Operation When the ON–OFF SW is turned on, the systems starts preparations for cruise control and turns on the indicator light in the combination meter. Set Speed Control When the – SET SW is operated with the ON–OFF SW turned on during driving, the speed is controlled at a constant speed. Coast Control When the – SET SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to decelerate the vehicle speed. Every time the – SET SW is turned on instantaneously, the vehicle speed is decelerated approx. 1.6 km/h. Accel Control When the + RES SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to accelerate the vehicle speed. Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approx. 1.6 km/h. Resume Control If the vehicle speed is within the low speed limit (Approx. 40 km/h, 25 mph) when canceling the cruise control, operation of the + RES SW accelerates the vehicle speed and resumes the level before canceling the cruise control. Manual Cancel Mechanism If any of the following signals are input during cruise control driving, the cruise control is canceled. ∗ The stop light SW is on ∗ The CANCEL SW is turned on ∗ The ON–OFF SW is turned off ∗ Gear is shifted from D or 4 position to other positions than D or 4. Auto Cancel Function If any of the following conditions are detected, the cruise control is canceled: ∗ Failure in the stop light SW wiring ∗ Abnormality in the vehicle speed signal ∗ Malfunction in the electronically controlled throttle parts ∗ When the vehicle speed gets slower than the low speed limit. ∗ When the vehicle speed falls to 16 km/h less than the set speed. ∗ During VSC operation. Shift–Down Control When the vehicle climbs a hill while running under cruise control, the gear may be shifted down by the A/T control. When the hill climb is judged to have finished, based on the throttle opening information, the gear is shifted up after a set time. : Parts Location Code A9 See Page A 38 B 38 38 A15 Code E11 See Page

factors. In such a case, this system automatically controls the engine output and the braking to each wheel, to decrease the extreme over steering and under steering. ∗ To decrease extreme over steering tendency When the system determines that the over steering tendency is large, the system applies brakes to the outer wheels according to the degree of over steering, and creates a moment towards the outer side of the vehicle, to decrease the tendency of over steering. Also, when the brakes are applied, the vehicle speed decreases while the stability increases. ∗ To decrease extreme under steering tendency When the system determines that the under steering tendency is large, the system applies brakes to the front or rear wheels according to the degree of under steering, to decrease the tendency of under steering. ∗ Traction control SW Traction control SW is only for two–wheel drive models. Four–wheel drive models is needless this SW. The SW to send the traction control system into OFF mode. When the SW is pushed after starting the engine, the system will be in OFF mode, and the traction control SW indicator light will turn on. When the SW is pushed again, the system will be in standby mode. When the engine is stopped and re–started, regardless of the traction control SW, the system will be in standby mode. Information to the driver The VSC system informs the driver when the tire grip is about to exceed its grip capacity, by blinking the slip indicator light and emiting an intermittent sound of the buzzer. Accordingly, the driver is informed to drive more gently. : Parts Location Code See Page Code 36 G4 39 J31 A 38 J1 37 J32 B 38 J2 37 J42 43 B 38 J5 A 40 J49 40 A27 42 J6 B 40 P6 A28 42 J7 A 40 B1 36 J8 B 40 S9 41 40 S12 41 B7 B 38 J15 C10 39 J17 D1 39 J18 36 See Page A4 A21 G Code 36 A9 F12 See Page A3 J28 S3 40 A 40 B 40 41 A 37 40 T5 41 A 40 V6 41 B 40 Y1 45 E5 B 39 F6 A 36 J19 40 F10 E 36 J20 40 : Relay Blocks Code See Page Relay Blocks (Relay Block Location) 5 27 R/B No.5 (Engine Compartment Left) 6 28 R/B No.6 (Engine Compartment Left) : Junction Block and Wire Harness Connector Code See Page 1C 31 1E 31 1H 30 1K 1L 2C Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 24 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) 267 SIENNA (EM0530U) ABS with VSC, TRAC and VSC : Connector Joining Wire Harness and Wire Harness Code See Page Joining Wire Harness and Wire Harness (Connector Location) IB1 52 Engine Room Main Wire and Floor No.1 Wire (Left Cowl Side Panel) IK1 53 Engine Room Main Wire and Instrument Panel Wire (Right Kick Panel) IL1 53 Engine Room Main Wire and Floor No.2 Wire (Right Kick Panel) : Ground Points Code See Page Ground Points Location EA 50 Front Side of the Right Fender Apron ED 50 Front Side of the Left Fender Apron IE 52 Left Kick Panel IF 52 Instrument Panel Brace LH IG 52 Right Kick Panel BL 54 Right Rear Quarter Panel 268 SIENNA (EM0530U) Memo 269 SIENNA (EM0530U) Battery 1 A 3 B 17 A Y–G R G LG L 11 A 10 A D/G PKB 17 B 3 A GND1 TC TS 1 ED 270 SIENNA (EM0530U) G 6 IB1 5 IB1 RL+ GND2 7 1C 1 E 13 B FL+ 26 B 1 2 6 RL– FL– IL1 RR+ FR+ 10 1K 1 2 L LG R J 5(A), J 6(B) Junction Connector Y–G 22 B J 7(A), J 8(B) Junction Connector P–B 23 B 27 B 28 B Y P–B GR–R P–B A27 ABS Speed Sensor Rear LH Y–G W 10 1L A28 ABS Speed Sensor Rear RH 2 B GR–R 9 1L 12 A4 ABS Speed Sensor Front RH 23 B W–B +BS TC O 1 B W–B W 14 1K 13 L–W 12 B R–L B–R SIL A3 ABS Speed Sensor Front LH J 5(A), J 6(B) Junction Connector R–W B–R W 1 28 1K 7 W–B FL MAIN 3. 0W R–W 3 G 50A ABS1 30A ABS2 +BM W–B P6 Parking Brake SW W F 6(A), F10(E), F12(G) Fusible Link Block ABS without VSC D1 Data Link Connector 3 TS 2 1 2 IL1 24 B 2 B 11 B 8 B 10 B 7 B 6 B 5 B 4 B RR– S 3(B) Skid Control ECU with Actuator FR– (BAT) (IG) 10A ECU–IG 10A STOP 10A GAUGE1 6 1C 26 1L R W B–R 16 1C C (IG) 85 J15 Junction Connector C J18 Junction Connector R W 75 2 17 J2 Junction Connector II3 P S12 Stop Light SW G–W A A B–R B G–W 1 16 B 3 B J47 Junction Connector B P IG1 STP S 3(B) Skid Control ECU with Actuator 2 P1 Park/Neutral Position SW P BRL 19 B P N 14 B 15 B WA 30 B N L–Y Y–R II3 L–Y 6 76 71 86 81 L–Y II3 Y–R 23 B Y–R 22 B 9 A J 5(A), J 6(B) Junction Connector 8 A 6 Y–R Y–R L–Y 5 L–Y R–W Y–B 9 J20 Junction Connector R–W Y–B 271 SIENNA (EM0530U) ABS without VSC (IG) (BAT) 10A ECU–B 7. 5A GAUGE2 25 1H W–L 8 2C B–R ∗ 3 : USA ∗ 4 : Except USA 24 1C C10 Combination Meter 32 IG+ 7 1L ABS Brake (∗4) BRAKE (∗3) W–L POWER SUPPLY CIRCUIT 15 A 17 A 5 A 35 J19 Junction Connector 17 B J 7(A), J 8(B) Junction Connector 5 B 54 1 B1 Brake Fluid Level Warning SW Y–R W–L Y–B R–W 3 B 12 W–L 30 Y–R 13 Y–B 14 R–W 7 BR ACTIVE CIRCUIT A R–W J1 Junction Connector W–B 2 A EA BR W–B Y–B IF 272 SIENNA (EM0530U) System Outline ABS system controls the respective brake fluid pressures acting on the disc brake cylinders of the four wheels when the brakes are applied in a panic stop, so that the wheels do not lock. This results in improved directional stability and steerability during panic braking. Tire pressure warning system turns on the tire pressure warning light and warns the driver of low tire pressure, when driving with a low tire pressure, which may cause trouble driving. However, this system can detect the low tire pressure condition only if one of the tires has such a condition in particular compared to other tires, and it cannot detect. Therefore, it can not detect natural (Gradual) air loss occurring to the tires. 1. Input Signals (1) Speed sensor signal The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the skid control ECU with actuator. (2) Stop light SW signal A signal is input to TERMINAL STP of the skid control ECU with actuator when the brake pedal is operated. (3) Parking position signal A signal is input to TERMINAL P of the skid control ECU with actuator when the Shift lever at ”P” position. (4) Neutral position signal A signal is input to TERMINAL N of the skid control ECU with actuator when the Shift lever at ”N” position. 2. ABS System Operation During sudden braking the skid control ECU with actuator has signals input from each sensor, which controls the current to the solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump inside the actuator is also operating at this time, and it returns the brake fluid from the reservoir to the master cylinder, thus preventing locking of the vehicle wheels. If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current on the solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the skid control ECU with actuator, by the same method as above. Pressure reduction, holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking. : Parts Location Code See Page Code F12 See Page A3 36 G A4 36 A27 42 A28 42 J5 A B1 36 J6 C10 39 D1 39 Code See Page 36 J19 40 37 J20 40 37 J47 40 40 P1 37 B 40 P6 J7 A 40 J8 B 40 J1 J2 F6 A 36 J15 40 F10 E 36 J18 40 S3 41 B S12 37 41 : Junction Block and Wire Harness Connector Code See Page 1C 31 1H 30 1K 1L 2C Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 24 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) : Connector Joining Wire Harness and Wire Harness Code See Page Joining Wire Harness and Wire Harness (Connector Location) IB1 52 Engine Room Main Wire and Floor No.1 Wire (Left Cowl Side Panel) II3 53 Engine Wire and Instrument Panel Wire (Right Kick Panel) IL1 53 Engine Room Main Wire and Floor No.2 Wire (Right Kick Panel) 273 SIENNA (EM0530U) ABS without VSC : Ground Points Code See Page Ground Points Location EA 50 Front Side of the Right Fender Apron ED 50 Front Side of the Left Fender Apron IF 52 Instrument Panel Brace LH 274 SIENNA (EM0530U) Engine Immobiliser System (BAT) (IG) 7. 5A IGN 10A ECU–B 7. 5A GAUGE2 D1 Data Link Connector 3 (IG) SIL 7 25 1H 13 1H 8 2C I14 Transponder Key Amplifier Transponder Key Coil J19 Junction Connector 12 1H ANT1 VC5 25 CODE 39 36 W 28 1K B–O 7 BR–R GND 5 Y–R TXCT Y 4 26 Y–B 1 29 W–L B–R 24 1C ANT2 1 8 11 12 13 2 9 VC5 CODE TXCT AGND IG D W–L +B J18 Junction Connector 7 1L 54 35 W W B–O W–L W–L CTY IND L–W J18 Junction Connector 6 A 22 B K4 Unlock Warning SW 1 31 W–B R–Y C10 Combination Meter L–B 2 J18 Junction Connector Security B6 Body ECU J11(A), J12(B) Junction Connector 24 14 80 R–Y B 4 +B POWER SUPPLY CIRCUIT 40 58 B 12 38 64 GND 10 R–Y B J18 Junction Connector 34 24 32 KSW 4 W–B T6 Transponder Key Computer J18 Junction Connector IND 3 21 1 1 D7 Door Courtesy SW Front LH IF W–B BR 30 IE 90 SIENNA (EM0530U) BR–W BR–W BR–R 39 BR–R 23 6 7 15 B 16 B EFIO EFII ME01 3 D E04 7 D W–B W–B W–B W–B W–B W–B W–B W–B W–B E01 7 C E05 6 D E03 4 D J20 Junction Connector 70 E02 6 C W–B EOM 35 B BR E1 1 E IMI W–B IMO E 5(B), E 9(C), E10(D), E11(E) Engine Control Module BR 80 BR II3 A A J48 Junction Connector BR 8 A W–B T6 Transponder Key Computer J19 Junction Connector BR–R 29 J18 Junction Connector BR–W 33 EB EC 91 SIENNA (EM0530U) Engine Immobiliser System : Parts Location Code See Page Code See Page Code See Page B6 38 E9 C 39 J18 40 C10 39 E10 D 39 J19 40 D1 39 E11 E 39 J20 40 D7 42 39 J48 40 I14 E4 A 39 J11 A 40 K4 40 E5 B 39 J12 B 40 T6 41 : Junction Block and Wire Harness Connector Code See Page 1C 31 1H 30 1K 1L 2C Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 24 Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) : Connector Joining Wire Harness and Wire Harness Code II3 See Page 53 Joining Wire Harness and Wire Harness (Connector Location) Engine Wire and Instrument Panel Wire (Right Kick Panel) : Ground Points Code See Page Ground Points Location EB 50 Rear Bank of Right Cylinder Head EC 50 Rear Bank of Left Cylinder Head IE 52 Left Kick Panel IF 52 Instrument Panel Brace LH 92 SIENNA (EM0530U) Memo 93 SIENNA (EM0530U) SRS NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions and the procedure, and precautions in the Repair Manual applicable for the model year. D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. D Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and the negative (–) terminal cable is disconnected from the battery. (The SRS is equipped with a back–up power source so that if work is started within 90 seconds from disconnecting the negative (–) terminal cable of the battery, the SRS may deploy.) D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. However, it is not possible to make a record of these memory contents. So when the work is finished, it will be necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each system, never use a back–up power supply from outside the vehicle. D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair. D Do not expose the following parts directly to hot air or flame; D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected; D Never use SRS parts from another vehicle. When replacing parts, replace with new parts. D For the purpose of reuse, never disassemble and repair the following parts. D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector, replace with new one. D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system. D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice. D After work on the SRS is completed, check the SRS warning light. D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ Steering wheel pad Front passenger airbag assembly

following device based on the signals received from the front airbag sensor and deceleration sensor. – Driver Airbag – Front Passenger Airbag – Seat Belt Pretensioner ∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the side airbag sensors. – Side Airbags – Curtain Shield Airbags ∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls the optimal airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened (driver seat) and information from the front passenger occupant classification system. ∗ The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult or child (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat belt is buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, and front passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through the use of the AIRBAG ON/OFF indicator lights. ∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump when the airbag is deployed. : Parts Location Code See Page Code See Page A7 36 C10 39 A8 36 C14 39 Code O5 See Page 46 (*1) 47 (*2) A9 A 38 C15 39 A10 B 38 C16 42 A 38 C17 42 D 38 D1 39 B 38 E5 39 C 38 G4 39 E 38 J17 40 P44 44 A23 38 J18 40 P45 44 A24 38 J19 40 S14 45 A20 A21 A22 B7 B B17 46 (*1) 47 (*2) 46 (*1) 47 (*2) A 40 S15 45 46 (*1) J34 B 40 S16 45 40 S17 45 47 (*2) 46 (*1) B O8 47 (*2) J33 46 (*1) B18 O7 46 (*1) 38 47 (*2) A O6 47 (*2) J49 O3 O4 A B 46 (*1) 47 (*2) 46 (*1) 47 (*2) S18 S19 46 (*1) 47 (*2) 46 (*1) 47 (*2) : Junction Block and Wire Harness Connector Code See Page 1C 31 1E 31 1H 30 1K 1L 2C Junction Block and Wire Harness (Connector Location) Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 31 24 * 1 : Front Seat w/ Power Seat Engine Room Main Wire and Engine Room J/B (Engine Compartment Left) * 2 : Front Seat w/o Power Seat * 3 : Rear No.2 Seat 281 SIENNA (EM0530U) SRS : Connector Joining Wire Harness and Wire Harness Code See Page Joining Wire Harness and Wire Harness (Connector Location) IC1 52 Engine Room Main Wire and Instrument Panel Wire (Near the Driver Side J/B) IK2 53 Engine Room Main Wire and Instrument Panel Wire (Right Kick Panel) IN2 53 Instrument Panel Wire and Instrument Panel Wire (Under the Combination Meter) BM1 57 (*2) Floor No.2 Wire and Seat No.1 Wire (Under the Front Passenger’s Seat) BO1 56 (*1) Seat No.1 Wire and Floor No.2 Wire (Under the Front Passenger’s Seat) : Ground Points Code See Page Ground Points Location IE 52 Left Kick Panel IF 52 Instrument Panel Brace LH BI 54 Under the Right Center Pillar * 1 : Front Seat w/ Power Seat * 2 : Front Seat w/o Power Seat * 3 : Rear No.2 Seat 282 SIENNA (EM0530U) Memo 283 SIENNA (EM0530U) Tire Pressure Warning System (IG) D3 Data Link Connector 3 10A ECU–IG TC SIL W 14 1K 28 1K 34 1H 12 1H V–W RDA IND 9 5 17 ID1 19 ID1 18 ID1 G–B G–B GND 12 P–L 6 SPD 3 IQ1 2 IQ1 4 IQ1 W–B 2 RF5V P–L 1 GND2 11 2 SIL P T4 Tire Pressure Warning Reset SW L–O 1 10 TC P CLSW 3 GR–L IG W–B T15 Tire Pressure Warning ECU 7 26 A (∗1) 26 B (∗2) J18(A), (B) Junction Connector 46 A (∗1) 46 B (∗2) W 99 J19 Junction Connector 89 P–B B–R 87 A (∗1) 87 B (∗2) J18(A), (B) Junction Connector 37 A (∗1) 37 B (∗2) V–W W P–B B–R 23 1L 7 P–B 13 P P–L 4 5 1 GND +5V RDA J18(A), (B) Junction Connector W–B 1 A (∗1) 1 B (∗2) G–B GR–L 123 A (∗1) 113 B (∗2) T16 Tire Pressure Warning Antenna and Receiver IE 284 SIENNA (EM0530U) W–B (BAT) (IG) 10A ECU–B ∗ ∗ ∗ ∗ 7. 5A GAUGE2 : Automatic A/C : Manual A/C : w/ VSC : w/o VSC 25 1H W–L 8 2C 1 2 3 4 V–W 24 1C 45 B–R J19 Junction Connector 54 J20 Junction Connector 65 W–L V–W 7 1L V–W W–L 35 36 12 C10 Combination Meter 32 IG+ IG+ Tire Pressure POWER SUPPLY CIRCUIT Speedometer IG+ MICRO COMPUTER GR–L 35 4 B GR–L GR 16 A J 7(A), J 8(B) Junction Connector 6 DRIVE IC GR 30 BR IG+ 12 A (∗3) 17 B (∗4) BR SP1 S 3(A), (B) Skid Control ECU with Actuator W–B IF 285 SIENNA (EM0530U) Tire Pressure Warning System System Outline The tire pressure warning valve and transmitter installed in the tire wheel detects the tire air pressure and transmits signals to the vehicle side receiver.

This inhibits to turn the ignition SW from on to OFF position. : Parts Location Code See Page Code See Page 39 40 K4 40 J2 37 J15 40 S8 41 40 J18 40 S12 41 A B Code F25 J3 J4 See Page : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) 1C 31 Engine Room Main Wire and Driver Side J/B (Lower Finish Panel) 1L 31 Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) : Ground Points Code IE See Page 52 Ground Points Location Left Kick Panel 293 SIENNA (EM0530U) Remote Control Mirror with Memory B 6(A), B 7(B), B 9(D) Body ECU (IG) 10A GAUGE1 MPX2 MPX1 21 B 14 : Automatic A/C : Manual A/C : w/ VSC : w/o VSC R–L 12 IM1 3 IA1 R–L 14 R–L 53 R–L 23 2 P P1 Park/Neutral Position SW R R–L II3 63 R–L R 24 B 33 R–G MPX1 R–L MPX2 J19 Junction Connector 13 A21(B) Airbag Sensor Assembly 22 B J18 Junction Connector 76 10 1 2 3 4 R–L R 85 R–L 7 1E 26 1L ∗ ∗ ∗ ∗ 6 1E 6 C10 Combination Meter L–Y 3 CA1H 17 J20 Junction Connector J19 Junction Connector B 32 71 CA1L 18 W R–L II3 L–Y 6 MPD2 V 28 12 MPD1 G4 Gateway ECU 29 32 1H B A B A V 62 L–Y 61 W(∗3) B B W(∗3) B(∗3) A A B(∗3) J17 Junction Connector B(∗3) B(∗4) W(∗3) W(∗4) W(∗3) B(∗4) B(∗3) MPX– 3 A (∗1) 5 B (∗2) W(∗4) CANL 34 B A 9(A), (B) A/C Control Assembly CANH MPX+ R–L P 33 B 2 A (∗1) 4 B (∗2) E 4(A), E 5(B) Engine Control Module 6 A R–L R–L J49 Junction Connector 294 SIENNA (EM0530U) B 6(A), B 7(B), B 9(D) Body ECU (ACC) MIRS MIRE LG–B P Up Right Left Right 88 J18 Junction Connector P 98 J18 Junction Connector 21 Return Retraction MR MF 7 A 8 A 32 42 1 Return Retraction E2 4 A B 6 A V R W–B W–B 1 1 J20 Junction Connector 2 D7 Door Courtesy SW Front LH K4 Unlock Warning SW R–Y 22 B 8 1L J11(A), J12(B) Junction Connector L–B 6 A Left Right 58 Left 80 3 A M+ J18 Junction Connector 48 R17(A) Remote Control Mirror SW MSW R–Y 70 E 11 A P–L LG–R 1 A R–Y 2 A L–B 3 A 7. 5A ECU ACC MIRB 12 A 14 D Down DCTY KSW 21 A 19 J19 Junction Connector 93 J18 Junction Connector 60 20 82 92 R R V V 16 IM1 16 IA1 15 IM1 6 IA1 M V V R Control Circuit R W–B W–B O13 Outer Rear View Mirror LH 4 3 V R R–L R–L R–L R–L IE IG 295 SIENNA (EM0530U) Remote Control Mirror with Memory (BAT) (BAT) (IG) 25A P/W 10A ECU–B 10A ECU–IG 21 1K 34 1K 8 2C 23 1L W–L R–L R–L W–L 24 1C B–R B–R S33 Seat Memory SW J19 Junction Connector 57 R–Y 12 IA1 4 BT1 5 BT1 6 BT1 7 BT1 B–R B–W V W–R 4 A 6 A 3 A 22 A 23 A 25 A HSSR DE2 DMHR DM+R DMVR P O LG 1 B GR 10 B L 9 B G 14 B Y 13 B 15 17 16 18 12 11 10 SEL1 8 A 21 A MM GND 1 A M W–B M MPX1 M2 W–B VSSR 6 B M1 SIG W–B DVC 5 B BDR R–L CPUB W–B W–B 1 LG–B E 2 P–L MMRY 3 B–R 2 4 R–L 12 IA2 1 W–L 13 IA1 O 9(A), O10(B) Outer Mirror Control ECU LH 87 47 W–L 17 B–R 56 J18 Junction Connector W–L 54 R–L W–L 7 1L 1 IA1 W–B O13 Outer Rear View Mirror LH V V R R R–L R–L R–L IE 296 SIENNA (EM0530U) R–L W–L R–L 9 IM1 R–L W–L 10 IM1 W–L 11 IM1 B–R B–R B–R 3 A 4 A 6 A CPUB VSSR HSSR PE2 PMHR PM+R PMVR MPX1 LG 8 A O 1 B P 10 B GR 9 B L 14 B G 13 B Y 6 B 15 17 16 18 12 11 10 GND 1 A W–B PVC 5 B BDR R–L SIG O11(A), O12(B) Outer Mirror Control ECU RH M M M Control Circuit 4 3 O14 Outer Rear View Mirror RH 2 IM2 V W–B R R–L IG 297 SIENNA (EM0530U) Remote Control Mirror with Memory System Outline When the ignition SW is turned on, the outer mirrors can be operated. When the remote control mirror SW is operated, a signal is input to the body ECU, and the outer mirror can be adjusted to the desired position. In this system, the position sensor detects the number of rotations of each motor (Movement amount of each mirror) and inputs it to the outer mirror control ECU LH and outer mirror control ECU RH. This makes it possible to store and recall the outer mirror position using the seat memory SW. The outer mirror position is stored and recalled through communication control of the body ECU. : Parts Location Code A9 See Page A 38 Code See Page G4 39 Code See Page O10 B 43 B 38 J11 A 40 O11 A 43

B = Black W = White BR = Brown L = Blue V SB = Sky Blue = Violet R = Red G = Green LG = Light Green P Y GR = Gray = Pink = Yellow [F] : Junction Block (The number in the circle is the J/B No. and the connector code is shown beside it). Junction Blocks are shaded to clearly separate them from other parts. Example: 3C indicates that it is inside Junction Block No.3 O = Orange The first letter indicates the basic wire color and the second letter indicates the color of the stripe. Example: L–Y [G] : Indicates related system. SIENNA (EM0530U) L (Blue) [H] : Indicates the wiring harness and wiring harness connector. The wiring harness with male terminal is shown with arrows ( ). Outside numerals are pin numbers. Y (Yellow) [C] : The position of the parts is the same as shown in the wiring diagram and wire routing. [D] : Indicates the pin number of the connector. The numbering system is different for female and male connectors. Example : Numbered in order from upper left to lower right Numbered in order from upper right to lower left Female [I] Male ( ) : ( ) is used to indicate different wiring and connector, etc. when the vehicle model, engine type, or specification is different. [J] : Indicates a shielded cable. Female Male The numbering system for the overall wiring diagram is the same as above [E] : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown to distinguish it from the J/B. Example : [K] : Indicates and located on ground point. [L] : The same code occuring on the next page indicates that the wire harness is continuous.
