4wd Question

[sinstr]

Hey all,

I just have a question regarding the 4WD on my R32 GTR, I have searched this topic and read thouroughly over all topics posted regarding this.

A couple of weeks ago my alternator put a massive surge of power through my car, frying many electrical components one of these I think could be my 4WD computer.

OK so at this stage I am not getting any 4WD, there is no 4WD light on in the car and I have checked the computer for diagnostic error codes, it doesnt have any lights on the 4WD computer, I have also checked all fuses and they seem to be OK.

So stating that do you's think that it would most likely be the 4WD computer that is causing my problems, are there any other electrical components that may have been fried? Is there any way of testing that it is definately my 4WD computer without swapping it over as I dont have another to test.

I also have a 2WD/4WD switch in the car, if this was fried would it prevent 4WD from working? Would I be best to remove this to be 100% sure?

And if it does come down to swapping over the 4WD drive computer is it just a case of unplugging old one and plugging in new one?

Thanks alot,

Cheers,

Mitch.

No one has any ideas, please if someone knows a bit about this please post up! I dont wanna spend the $$$ on a new 4WD computer to find that it may not be the problem.

Cheers,

Mitch.

Thanks a lot for your reply mate, where abouts will I find the relays for the 4WD?

In the fuse panel under the bonnet... (Mine is fresh from Japan and still shows which one is for the 4WD)

and also fuse in the fuse panel.

Quick search on here should pretty much cover which fuse is which.

Easy option though is to simply run a test light over all the fuses and see if any are blown and may as well replace them while you are going. Only gotta touch the small sections in the back of each fuse and see that the light lights up both sides. Should take all of 5 minutes including getting the test light.

Excellent! thanks mate, I will check these out and just replace all 4WD fuses / relays and see how I travel.
