forgot to mention I have 1994 R33 GTS4,

One thing I noticed is once the 4WD and ABS led flashes the SLIP led doesnt work anymore, normally it flashes when the rear wheels loos control or slips. which means it has switched back to RWD from 4WD.mmmmmmm, No I dont know why ABS led allways cometogether with 4WD??????

Maybe a electrical problem.................. :):):mad:

Sounds like you rear ABS sensor/s are faulty or damaged.

Both ABS and ATTESSA systems use the ABS sensors to determine slip/skiding/etc.

I took my car to a workshop, which they hook it up to a handheld computer thingy, it came up saying "G sensor error"

By the way where is the ABS sensor can be found on ? im sure all 4 wheels got them but no idea what it looks like or where it is exactly located in?

any help...................a pictur maybe...

The G sensor is a small metal box in the centre console rear of the gearshift. You will see it as soon as you take the console off.

It has a small window on the front which apparently goes red when the sensor is busted - don't forget your problem could be the wiring between the sensor and the computer as well

The ABS sensors are little toothed wheels - front ones are on the hubs and rear ones are next to the diff. There is a small sensor attached to the diff or hub that reads how many teeth go by to calculate wheel speed.

FYI----(The following has been copied from above mentioned site)

If you disconnected the battery you may of just deleted all the fault codes from the ECU,s that have recorded the faults.

Over the last few years we have come to notice what causes these faults and mostly are as follows in order which we have noticed.

A 33 has Electric Hicas so the Power steering fluid fix will not work ( the 32 is the only car that has hyraulic Hicas )

Normally if the 4wd lights comes on by itself it will be a low fluid level.

If the 4wd lights and ABS lights come on it will be throttle switch or ABS sensor.

If the 4wd/ABS/HICAS lights come on normally the rear wiper pipe broken and it has flooded the ECU,s in the boot.

what exactly is the throttle switch?

having just messed around with the throttle getting wiring through the fire wall my 4wd + ABS lights have come on. Guessing its related.

      I mean it's a bit late to say "This won't have any tangible effect and it is not worth spending more than about three seconds on it, please just enjoy the car" But I said it anyway. Does the pod actually get any airflow in that position behind a bumper like that?

      Hey guys - apologies for digging this up. Has this website been shutdown or is the outage temporary?

      So, went shopping at Just Jap for things that might work for the intake  After some trial fitting there I ended up with a 3" x 45° silicone bend, a 3" x 300mm alloy straight, and a humped joiner, some minor trimming will be required to shorten some of the stuff, but nothing that is beyond my "ham fisted" skills The guy at Just Jap was most helpful as we had all sorts of joiners,  bends and stuff out trial fitting  Laying it out above the stuff in there it seems everything will fit nicely, and looking at it, it is probably the way I should have been looking at doing it from the beginning, probably..... In the end it is a front bar off job anyway to remove the original stuff behind the front bar that is taking up the required realestate needed, so maybe a Thursday or Friday job And because I'm a hopeless consumer, I grabbed some new steel wheel nuts, the current ones are a spline drive type with a "security" socket, that somehow someone keeps misplacing, the new ones are a basic black steel 17mm hex socket In other news: I just did my "final" tax return, I am now officially a old retired veteran pensioner, and I'm milking the system for all it's worth,  life is good

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
