R33gtr Attesa Problem

[Deano45]

I have a mate who is having problem with his Attesa system on his 33 GTR V Spec. His car is in constant 2WD and he is frying his rear tyres when he puts his foot down and the car comes on boost. He has done some of the diagnostics on it and thought it was the Attesa computer, but I lent him mine out of my 33 VSpec and it didn't make a difference. He said that it reset itself and started working when he plugged my in but then stopped working again. He then put his computer back in and it did the same thing. I asked him to look at the torque split gauge and he said that it sits at zero.

Any ideas?

Step 1 - check that the AWD warning light in the dash is working.

Step 2 - check the fluid in the attessa reservoir.

Step 3 - check for fluid leaks at the rear on drivers side of the car.

If you havent done so already check if the 4WD light is coming on the dash, if so look up underneath at the attessa computer and the LED there should give off a sequence of flashes.

Match this sequence of flashes to the error codes listed in the user manual or search this site for them.

Good Luck.

Thanks for that.

I just spoke to him. He said that both the 4WD and LSD lights come on. With the flashing LED he said that it gives off 5 slow flashes then 7 quick ones. If someone knows what it means could they let me know. I'll do a search on here also (so far haven't found anything matching the code it listed, which I believe is 57?). One of the mechanics he got to look at it seems to think it could be the ABS sensor. He just wants to be sure before forking out money for a new sensor.

its 5 and 7

5 is ABS right front wheel actuator solenoid or circuit

7 is ABS rear wheel actuator solenoid or circuit

he has an ABS issue

Looks like he was on the right track. I'll let him know.

Thanks for the info

That would have been a useful piece of f@#$n information to have in the first place.

Fire Up!!!

Sorry mate if I wasted your time, as I said in my first post it wasn't my car and I was getting 2nd hand information. Once I knew what questions to ask him, I was able to get the right info from him. I don't know the attesa system, so I didn't know what to ask him about, hence why I posted in here. That's the original idea of a forum - to share info and learn.
