R32 Gtr Possible Attessa Issue?

[Midnight_Blue_32]

Hi, just curious to know if my awd system is working correctly or has an issue that hopefully the gtr gurus could point me in the right direction if theres a fault somewhere. Since the only gtr ive been in is my own i dont have anything to compare it to.

Basically the 4wd light comes and goes as it pleases randomly for no apparent reason, but it will decide to work correctly about 50% of the time, would there be any reason for it to do this (system has been bled, no fault codes and tyres/rim are all the same sizes). Any possible idea?.

Also ive noticed that when the awd system is working it works completely fine when going straight but if cornering it seems that its all rwd, even under hard acceleration. Is this normal? Or have i got a fault somewhere?

There is a few threads in here you can search

My advice to most is a new Nitrogen canister (original is 25yo and very likely not doing it's job) and a new digital G Sensor (also very old and slow technology)

and if you want to go a good step further have the transfer case o'hauled and tightened up.

Cheers

When the light is on chack the fault code, ECU under parcel shelf will have an orange light flashing, count the flashes and google search it and the answer will come up

To replace the nitrogen canister, is it just unscrew the old one and screw the new one in?

Yeah you can just unscrew the canister and replace with a new one from memory, reading the FSM instructions. They are like $250-300 for a new one, not too bad.

think it's rear diff out/down in the 32

No, can be done with everything on the car (even the exhaust, although does make it easier) after 26 years mine was pretty tight and i had to machine a custom socket to get it off. using a g-clamp as i had read in another thread resulted in the canister unscrewing itself which could be pretty dangerous if the thing still had change, surprised they didn't make it with a left hand thread to avoid that ever happening. Was definitely worthwhile to replace the canister, overlooked by the vast majority i reckon.
