Nissan Cooling Fan Wiring The fsm also describes testing the various harnesses and connections between the relays, fan motors, and the cpu. the cpu is supplying the 12v to the motor windings and the relay operation supplies the ground. the relays supply ground to various windings of the motors for the different speeds. the fsm also cautions not to overheat the engine. Testing your 350z cooling fans for power. put the black lead of your multimeter to the negative battery terminal, and then gently probe pin a first for a power signal. then check pin b in the 350z cooling fans wiring diagram as shown below. you have two speeds that operate through your nissan radiator fans. at low speeds, the power wire is the.
Nissan Cooling Fan Wiring I did the ipdm e r auto active test the fsm calls for. in that test it is supposed to turn the fan on at 50% duty cycle for 5 seconds and 5 seconds at 100% duty cycle. the fan barely turns at all. i am going to attempt to troubleshoot the cooling fan power control module, but it is going to be a pain because none of the connectors are labeled. Each fan has four wires. if it was two and two, i could get that quickly, but each fan has a four prong connected and two wires running to each side of it. yes each fan has four wires, the colors i specd and the other 2 are grounds.fan 1, wht red, wht blu, blk, all these are on one side of the fan.on the other side is awht blk. 1. verify the fan itself is good or bad. disconnect the wiring to the fan. connect the fan itself directly to the car battery. if the fan runs directly off the battery (for at least several minutes) with no problem then the electrical fan relay is worth checking by replacement. 2. 1. first find the cooling fan schematics. 2. locate the ecu pinout for the cooling fan relay hi control. in this case, i am using a '95 ecu pinout that shows pin 13 for the cooling fan relay hi control. note: if you prefer manual control for only low fan speed operations then use ecu pin 14 instead for cooling fan relay lo control. 3.
