    Hi,
    I have a problem with some vdc, slip and abs lights coming on. I did have the truck scanned at the dealer and it came out with couple codes including the diff lock sensor. It seems to be consistant with the fact that it came on for the first time when i just disengaged the diff lock.

    Anyways, i was wondering if some of you knew how to diagnostic a broken diff lock sensor. From what I understand, it looks like a pain in the ass to replace and I dont want to change it if that is not the problem.

    My guess would be that it is a different resistance from the sensor depending od the position of the lock but I cant find those values anywhere. It might even be an open/close swith but I guess then the computer wouldnt be able to tell if the wire was cut or anything.

    Do you know where I could find the diagnostic charts for that or some wiring diagrams?

    Thanks.

    What were the other codes? A bad abs sensor or broken abs wire are the usual cause of the lights.

    Thanks guys, that link really helped. It turned out it really was the diff lock position switch that is bad. I tried tu disconnect it but I was disconnecting the actuator. I found in your link that I wasnt working on the right connector. Once unhooked, everything works normally.
    Now i just have to figure out if i replace the switch (seems like a pain in the ass) or if I leave it like that for now.

    Maybe i should flush the rear diff fluid to make sure i dont have a piece of the switch stucked in there that would cause damage.

    Thanks again, truly appreciated.

    Hi guys, I’ve bought a 2005 off road trim. The lock light keeps flashing as I switch the lock button. It does operate the lock tho. I think the problem is in the position sensor.
    Anybody knows where I can buy it? Or if anybody knows the part number for the sensor, still would be helpful.
    I took the sensor off but didn’t find any numbers on it.

    Thanks in advance

    I'll dig through the FSM when I get home tonight. I can't remember EXACTLY what they call that part. Nissan has a track record for naming their parts really stupidly. Once I find the name, I bet I can find the P/N.
