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.

Cheers, Thanks mate. bythe way i found more infor regarding this issue on another web site as well.

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.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
