R33 Gtr 4wd/abs/alsd Light Coming Up -> Rwd

[HKS26T]

Hi guys have posted this in the NSW section in a bid to get some local help as well

I have been trying to resolve this problem all weekend! (was up to 1am last night)

what i have noticed is that all three lights would either randomly come on during a lap or come up immediately upon starting.

This problem has progressively gotten worse and on the last meet was in RWD all day. Being so close to Superlap i would like to fix this asap.

Seached Altessa Diagnostics on the forums and attempted to follow the instructions to run it and get a fault code but had no sucess. (Trying to

ground termal #4 on the diagnostics plug (pink wire?) whilst ignition on and a drive of 30km/h for a min) - this did not make the ABS light flash at

all - does anyone have any experience with this - is there something i need to be aware of - also the red flash on the altessa computer

seems to remain red all the time.

What i did then was address the following - still with no sucess

1. Bleed the 4wd system - ensuring there is correct amount of fluid

2. Check TPS voltage signal being sent of ecu.

3. Changed each wheel sensor

4. Changed G-sensor

5. Went to change 4wd unit and realised that there is a difference with a non-vspec - sourced one this morning

6. Swapped Altessa computers over - no luck.

last effort tonight before i burn this is to switch the 4wd units over - Any constructive help with previous experiences or know how

will be greatly appreciated.

cheers

Steve

ive always had problems with my AWD light being on, but its still in AWD mode, if you find out how to fix it let me know.

My 4wd light started to flash on my r32 when it ran different circumfrence tyres front and rear, maybe this has something to do with it?

Problem on the 32 GTR was the TPS. It was still sending a signal, but not enough from memory.

We cranked it forward abit as a temporary fix. And a new one fixed it completely.

what voltage were you getting from the tps?
