4wd Light On

[Racer986jec]

Where do I start to diagnose this and is there a service manual online anywhere with the codes from the ATTESA Unit in the trunk ? , any advise is appreciated.

Dunno about the R33 GTR, but the official R32 service manual pdf is on the net in many places. The procedure for entering diagnostic mode is probably the same.

I would say though that it is far better to go to a workshop that has a good scan tool and hook that up to the Consult port than trying to get shit computers into diagnostic mode. It's much easier to read codes in plain text than try to interpret the bloody flashes on the dash!

The Google manual is Hektik bro

A bit more info would help

When does it come on, ie straight away or after driving for 1/2 hour etc

First check fluid in the reservoir in the boot

There is a fault code list somewhere that you count the flashing light on the ECU under the pacel shelf

Process is detailed in link provided.

Its on when the car is turned on -

its at the mark for max fluid

thanks - the car has been sitting for like almost 4 years when I got it.

Hey it isn't something as simple as a dicky switch controlling the 4WD indicator light is it.

Have you checked the fuse?

[MozzMann]

Good point Mr Antelope ,

I have seen systems that use power to keep the 4WD OFF and if there is no power then it drops to fail-safe mode with 4WD ON.

Have you bled it

One possible cause is insufficient level in the BRAKE fluid reservoir (I'm speaking from experience here).
