Gtr 4wd Problems

[itbmils]

Guys

for the past couple of days (maybe a week) my R32 GTR has been doing something quite odd

If I start the car and back out of a parking bay (@work) the AWD warning light comes on - it's seems to be dropping into the diag mode somehow – but I thought the ignition needed to be off for that to happen

It only seems to happen if a turn the car quickly. What I mean is when I back straight out of my drive way @ home where I reverse for about 7-10 meters before turning the wheel - it does not seem to happen.

If I turn the car off - and restart - all is fine

what the ?

NB – I have fit 8mm wheel spacers on all four wheels in the past few weeks – could this be causing me a problem

Sensor maybe?

Sensor maybe?

OK

so where are they ?

when the warning light is on open the boot and check the light on the ATTESA computer it will tell you what the problem is. A list of the error codes are in the workshop manual

OK Duncan

did this at last - when I checked the computer in the boot - all I could see was a steady and consistent flash (about 1 per second) – I stoped counting @ about 20

I do not have the WSM - so what does this mean ?

could the wheel spacers cause this

what about uneven tyer ware (front to rear) ?

[Duncan]

Its page C-67 and C-68 in the manual, and unfortunatley the flashes go to 29 so get back in the boot!

there is a 5 second gap between cycles but you'll need to get that count right.

There used to be a heap of links to the manual on here, maybe try a search?

[T04GTR]

yes, you need to get the corect code(s). but dont turn the car off if the lights come on.

[itbmils]

thanks guys

I'll do some digging

[itbmils]

OK

the light flashes 18 times - and acording to the manual that means either a faultly ETS Hydrolic unit or a faulty harness

can anyone tell me how to check for each - where is (are) the ETS hydrolic unit(s) for example ?

[Duncan]

Yep, the ETS hydraulic unit is the pump sitting above the diff. So it might be that has failed but I suspect its more likely to be a voltage problem, the system is very sensitive to voltage. You need to make sure you have at least 12v and a good earth, might be time to talk to an auto electrican
