Just recently, my R32 gtr every so often displays the ABS and the 4WD warning lights on the dash.. and when so, I know the ATTESSA system is definitely disabled and I"ve only got torque going to the rear wheels. Has anyone experienced this problem before or know how to rectify it?

I don't know why it has all of a sudden started to randomly do this, hot weather? ..I'm clutching at straws and have no idea. Perhaps a fuse is loose? But for both systems to go down suggests a computer problem. I am running a Microtech MTX-12 ECU.. and having only recently bought the car a few months ago I'm not aware if this is a piggy back sytem or outright ECU.

Help please!?

Possibly a fault with the ATTESA system, wether it be low fluid or something else. When the lights come on, pull over, dont turn the car off and pop the boot. Under the rear parcel tray is a silver box with a small led light in it which will be flashing. Wait till it stops for a few seconds then it will start flashing again. Count the number of long flashes and short flashes and it will give you a code (e.g 3 long flashes and 7 short flashes = 37 -- I think thats how it goes from memory, not 100% sure but it will flash you a code). Once you get the code I am pretty sure someone posted up here a list of the fault codes, if not download the R32 manual and it lists the codes in there. Check what code you were given against the list, then it will give you an indication of whats going wrong.

The most common problem is fluid in the attesa resevoir gets too low. In the boot on the right hand side theres a trimmed panel you can remove and the pumps behind this. When the car is running the fluid should be between the minimum and maximum lines on the bottle. If its low go to a Nissan dealer and pickup some Nissan "special power steering fluid" (also called Nissan Matic D), its about $13 from memory and top it up (or if youre super keen, flush the whole system and refill it all).

I had the exact same problem. I then after a while had my ABS really playing up. Brakes would momentarily (1 or 2 secs) go hard and have zero braking.

I took it too many places and no one could work out the problem. I finally found it after much trouble. Check on the outside of the rear diff that none of the dust covers (metal) which protect the speed sensor indicators (hope I have described this properly) have come loose. If they have they can momentarily block the speed sensor from getting the signal and both the ABS and 4wd system use these speed sensors and get totally confused.

Hope its as simple as this.

hi, this is my first post so bear with me;

my GTR just did the same thing this weekend and the flash code indicated the 'g' sensor. however my owners manual is a poor scan of the original and i cant make heads nor tails of where it is located,

anyone know its whereabouts?

fanx

i had the same problems when i first picked up my gtr.... so i had the attessa fluids topped up and the hicas bleed, changed the battery and bobs your uncle... havent had any problems since.. and for ari666 ... the g sensor is exactly where djr81 stated.. just unscrew your centre console and take it off and you will find a goldish box (wif a white tab and a red led light in the middle of it) situated next to your hand break lever ... thats the g sensor.. if its gone screwy you might want to just simply change it...and if you do.. go to the wreckers to find 1 as there relatively cheap as its not a sort after item as there pretty expensive from nissan

Check the fuse in the little kicker panel next to the steering collum.

There is a diagram on the back of the pannel that will tell you which fuse is which.. Its a long shot.. I know.. but that fuse controls both..

Its worth a go..

I have a similar problem or the same problem..

I got R32 GTR. I start it, and after a couple seconds the 4WD light comes on. (It doen't happen all the time. some times the car is normal) I thought it might be the camber of the raod giving the senser in the ATTESSA bottle a faulty reading, so I topped it up and I still have the same problem. Even starting the car on a flat serface it sometimes comes on.

If I start the car and immediately drive foward and back a couple of times just a few feet it SOMETIMES stas off and I'm all good. I'll check the speed sensor thing the other guy was talking about.

My guess is that its electrical and it really pissing me off.

Any one got any more I dears?

Cheers,

JUSTIN.

I know this is a real old post but I really need help.

My ABS and 4WD lights come on occassionally, especially after a while of driving and in warm weather.

My ATTESA silvcer box shows 4 flashes, meaning the rear left wheel speed-sensor fault? I'm tihnking to try clean the speed sensor trick

This is a silly question, but can anyone please upload a photo showing where I can find the wheel speed sensor?

Can I do it using a wheel jack? Thanks guys

I have really tried searching for this hence I have found the fault codes and possible fixes such as cleaning the speed sensors, bleeding the HICAS fluid, check g sensor voltage etc.

But I really can't find a photo showing which is the wheel speed sensor...

A photo would help greatly pleeeeeease

Thanks for the help guys! I think I have found them but they are an ass to clean without a proper car hoist..

For those who may have been struggling like me, below are photos (they are not located a bit different to other cars and do not come up in the first 2 rows of google :P)

Hey guys, I've got a 1990 R32 GTR and I have similar issues. My ABS and 4WD lights come on right away when turning the car on and they don't go away until the car is shut off. There are no Attessa ecu codes flashing. The fluid level is perfect with no air bubbles in the reservoir. The fuses are all fine. I'm pulling my hair out over it. Just looking for guidance at this point. Thanks in advance!

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
