CONRAD Posted September 17, 2004 Share Posted September 17, 2004 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!?

blind_elk Posted September 17, 2004 Share Posted September 17, 2004 Check your tyre pressures. I recall I got a similar situation when I ran the space-saver spare, which is a different rolling diameter from the normal wheels, on the front.

Amaru Posted September 17, 2004 Share Posted September 17, 2004 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).

rmc02 Posted September 22, 2004 Share Posted September 22, 2004 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.

KBNR32 Posted September 24, 2004 Share Posted September 24, 2004 i found out in my GTR that i had a shitty battery.. replaced it... and no more problems with the warning lights flashing on and off Link to comment https://www.sau.com.au/forums/topic/51307-r32-gtr-abs-4wd-warning-lights/#findComment-1024927 Share on other sites More sharing options...
ari666 Posted August 12, 2008 Share Posted August 12, 2008 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 Link to comment https://www.sau.com.au/forums/topic/51307-r32-gtr-abs-4wd-warning-lights/#findComment-4069233 Share on other sites More sharing options...

Player_Hater Posted August 12, 2008 Share Posted August 12, 2008 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 Link to comment https://www.sau.com.au/forums/topic/51307-r32-gtr-abs-4wd-warning-lights/#findComment-4069284 Share on other sites More sharing options...
GTS4WD Posted August 12, 2008 Share Posted August 12, 2008 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..

GTR_NUTZ Posted September 25, 2008 Share Posted September 25, 2008 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.

mcjiuman Posted April 26, 2015 Share Posted April 26, 2015 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 Link to comment https://www.sau.com.au/forums/topic/51307-r32-gtr-abs-4wd-warning-lights/#findComment-7523307 Share on other sites More sharing options...

niZmO_Man Posted April 27, 2015 Share Posted April 27, 2015 My right rear wheel speed sensor comes up when my ATTESA craps out. I tried changing it, impossible to do without dropping the diff it seems.

mcjiuman Posted April 27, 2015 Share Posted April 27, 2015 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...

GTSBoy Posted April 27, 2015 Share Posted April 27, 2015 Really? Toothed wheel next to the diff, each side. Front ones look similar but are at the hubs. If I google "Nissan wheel speed sensor" for you and find a suitable picture in the first 2 rows of hits, I'm going to have to come around there and smack you.

niZmO_Man Posted April 28, 2015 Share Posted April 28, 2015 Climb under your car and stare at the diff until you can see teeth and little cylindrical things.

Joel_Boisvert Posted August 14, 2017 Share Posted August 14, 2017 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!

GTSBoy Posted August 14, 2017 Share Posted August 14, 2017 Take it to a mechanic and put a scan tool on it. That way you can interrogate all the CUs in the car. 1 Link to comment https://www.sau.com.au/forums/topic/51307-r32-gtr-abs-4wd-warning-lights/#findComment-7844655 Share on other sites More sharing options...
