Nissan "Hidden" Fuses Of the tens of thousands of requests for assistance received by Auto{ech via the Technical Helpline, one reoccurring request is for the location of fuses; in particular, those found on current model Nissans. Power Supplies and Grounds In many cases, the ground locations are not obvious, so it makes sense to start with what should be the easiest to find part; the fuses. Often, fuses are checked without identifyingwhat function they are used for. This procedure may miss the fuses relating to the problem unless all fuses are located. Technicians know that one of the first things that should be done when there are electrical problems is to check power supplies and grounds. Let's Check The Fuses..... So, where are they? The usual first step is to take a look under the bonnet for the major fuses. 1. Battery Post Starting at the Battery Post we notice some large fusible links. These test OK. Battery Terminal Fusible Links 2, Underhood Fuse Box Next, we find the obvious Underhood Fuse Box cover and remove it. AII fuses and fusible links test OK. 3. lnterior Fuse Box As we can't see any others, we then head inside looking for the customary Underhood Fusible Links Interior Fuse Box. And there it is, not too hard to find behind a cover. All fuses test OK. At this point, all fuses test OK so there can't be a simple fuse power supply problem. Or can there be? Beware 0n These Models.... Interior Fuse Box On current platform Nissan vehicles, there is another "hidden" fuse location under the bonnet, specifically: . . . . . .

Locate The "Black Box" Look around for a flat topped looking "black box". On most Nissan models listed above, this will be on the left side of the engine bay. It could be at the back; such as on Navara or towards the front on other models. Release the retaining clips (usually 4) and carefully box. lift the black It will be clearly seen that there are many fuses located inside this module. Unfortunately, this is not clearly identified in the Owner's Manual D40 Navara / R51 Pathfinder Power Distribution Module Nissan call this black box the Power Distribution Module (PDM)' It is an electronic module in its own right and is wired into the CAN Communication Bus. It contains many fuses and relays such as: . . . . . . Headlamps. Tail lamps. Wipers. ABS. Air Conditioner. Engine control fuses, including fuel pump. "Hidden" Fuse and Relay Location PDM Active Test The Power Distribution Module has an Active Test function, that when enabled causes it to switch ON many of the systems that it contains relays and fuses for. This test allows us to confirm various circuits and their ability to function. If one of the functions below do not occur, then it confirms a fault in the circuit AFTER the Power Distribution Module. To initiate Active Test: 1. Switch Ignition OFF. 2. Close bonnet and Iift wipers off windscreen, close all doors - except driver's door. 3. Switch Ignition ON. 4. Within 20 seconds, press drivers door switch 10 times and switch Ignition oFF. 5. Within 10 seconds, switch Ignition back ON. 6. Active Test begins (Oil Lamp begins flashing and on some models the horn will chirp once). Step Test Item Operation Time/Frequency 1 Rear demister 10 seconds 2 Front wiper Low5secs.-Highbsecs. t Park Lamps (and Fog Lamps some models) 10 seconds 4 Fog Lamps (On some models) 10 seconds 5 Headlamps Low 10 secs. - High ON-OFF 5 times 6 A/C Compressor ON 2 secs. 7 Cooling Fans 2 speed = LowSsecs.-Hi5secs. 3 speed = Low2 secs. - Mid 2 secs. - OFF 2 secs. 5 times -Hi 2 secs. -Mid 2 secs. - Low2 secs. The test repeats for three cycles. Test can be terminated by switching Ignition OFF.
