(2) In each section, all specifications are listed, including optional specifications. Accordingly, some specifications may not be applicable for individual vehicles. Section Basic contents Wiring harness configuration diagrams Connector locations and harness wiring configurations on actual vehicles are illustrated. Single part installation position Locations are shown for each point of relays, electronic control units, sensors, solenoids, solenoid valves, diodes, inspection connectors, spare connectors, fusible links, fuses, etc. In the part’s lists, parts are listed in alphabetical order. Circuit diagrams Circuits from power supply to earth are shown completely, classified according to system. There is a main division into power circuits, and circuits classified by system. The circuits classified by system also include operation and troubleshooting hints. D Junction block The entire circuit for the junction block is described, because only the part of the junction block needed is normally shown in each circuit diagram. D Joint connectors The internal circuits for all joint connectors are described, because only the part needed is shown in each circuit diagram. D Power supply circuits Circuits from the battery to fusible link, dedicated fuses, ignition switch, general purpose fuses, etc. D Circuits classified by system For each system, the circuits are shown from fuse to earth, excluding the power supply sections. D Operation The standard operation of each system is briefly described, following the route of current flow. D Troubleshooting hints This is a brief explanation of the inspection points that serve as hints when troubleshooting. Explanations of the circuits controlled by the electronic control unit are omitted. Refer to the related publications as required. Index All components used are listed by connector number and component name. HOW TO READ THE WIRING DIAGRAMS - How to Read Configuration Diagrams A-3 HOW TO READ CONFIGURATION DIAGRAMS The wiring harness diagrams clearly show the connector locations and harness routings at each site on actual vehicles. Denotes connector No. The same connector No. is used throughout the circuit diagrams to facilitate connector location searches. The first alphabetical symbol indicates the location site of the connector and a number that follows is the unique number. Numbers are assigned to parts in clockwise order on the diagram. Example: A-12 Number specific to connector (serial number) Connector location site symbol A: Engine compartment B: Engine and transmission assembly C: Dash panel Denotes earth point. Same earth number is used throughout circuit diagrams to facilitate search of earth point. Refer to SINGLE PART INSTALLATION POSITION EARTH MOUNTING LOCATIONS for details of earth points. D: Floor and roof E: Door F: Luggage compartment A-45 Denotes a section covered by a corrugated tube. A-44 The mark L shows the standard mounting position of wiring harness. A-43 Denotes the colour of corrugated tube or vinyl tube. (If not specified, it is black.) R: Red Y: Yellow A-42 R A-39 The number of connector pins and the connector colour (except milk white)* are shown for ease of retrieval. Example: (2-B) Connector colour (milk white if no colour is indicated) Number of connector pins *: Typical connector colours B: Black Y: Yellow L: Blue G: Green R: Red BR: Brown V: Violet O: Orange GR: Gray None: Milk white A-39 (2-B) A-40 (1) A-41 (1) A-42 (2-B) Headlamp (LO: RH) Horn (LO) Horn (HI) Windshield washer motor Indicates the device to which the connector is to be connected. A-4 HOW TO READ THE WIRING DIAGRAMS - How to Read Circuit Diagrams HOW TO READ CIRCUIT DIAGRAMS The circuit of each system from fuse (or fusible link) to earth is shown. The power supply is shown at the top and the earth at the bottom to facilitate understanding of the current flow. Indicates that terminal is connected via a plate in the relay box. Indicates power take out. Indicates connector No. The same No. as in the wiring harness diagram is used. Connector numbers enclosed by frame are indicated with the connector symbols at the lower part of the page. Connector numbers not enclosed by a frame indicate components which are integrated with the harness. Each circuit diagram consists of block(s). The blocks are divided by page number. Indicates harness junction point No. for another system. It corresponds to the junction point No. indicated on the destination system circuit diagram. Indicates the circuit name to be connected. The arrow indicates the current flow direction. Indicates the power supply in the control unit. If no voltage is displayed, this indicates SYSTEM voltage. An “X” at the end of a connector No. indicates that the connector isconnected to a centralized junction that is shown in the section “CENTRALIZED JUNCTION”. Indicates that the diagram continues at A which belongs to the 2 block in the same circuit. Indicates the connector symbol. Connectors in the circuit diagram are indicated in numerical order. Indicates the operating conditions of the engine coolant temperature switch, etc. Indicates shield wire. Indicate that the current flows from down to up. Bi-directional arrows indicate that the direction of current flow changes when communication is in progress. HOW TO READ THE WIRING DIAGRAMS - How to Read Circuit Diagrams Indicates input/output to/from control unit (current flow direction). Input Output Input/ output A-5 Indicates a wiring connector which is inside the equipment and which is not shown in the wiring harness configuration diagram. Example C-15-2 Indicates a connector which is inside the equipment, numbered in order starting from 1. Indicates theconnectornumber shown in the wiring harness configuration diagram. A broken line indicates that these connectors are the same intermediate connectors. Indicates that the diagram comes from A which belongs to the 1 block in the same circuit. Indicates terminal No. In case two or more connectors are connected to the same device, markings indicating the same connectors are connected by a broken line. Indicates current flow downward or upward as controlled by the control unit. Indicates harness junction where wire diameter or colour changes. Indicates intersections at which the lead wire are not connected. Indicates intersections at which the lead wires are connected. Indicates representative vehicle body earth point. (Same No. as that of earth point in wiring harness diagram and installation locations of individual parts.) Indicates that the terminal is a spare one if the device (sensors in this case) is not provided. A-6 HOW TO READ THE WIRING DIAGRAMS - Markings for Connector Earthing MARKINGS FOR CONNECTOR EARTHING 3 5 1 8 3 4 2 7 6 HOW TO READ THE WIRING DIAGRAMS - Markings for Connector Earthing Item No. Connector and terminal marking 1 Connector/Earthing Symbol Male connector Male terminal Male terminal Male connector - A-7 Contents The male and female terminals are indicated as shown. The connector with male terminal(s) is called as male connector and indicated by double connector contour linens, while the connector with female terminal(s) is called as female connector and indicated by single connector contour line. Female terminal Female connector Female connector Female terminal Connector symbol marking 2 Device Intermediate connector Spare connector, check connector The symbol indicates the vehicle connector as viewed from the illustrated direction. At the connection with a device, the connector symbol on the device side is shown, and for an intermediate connector, a male connector symbol is shown. shown For spare connectors and check connectors, no device is connected, and so the harnessside connector symbol is shown for these connectors. The details for the diagnosis connector differ from the above description.
