Good Morning everyone,

I own a 1995 R33 GTR (non VSpec) and yesterday I noticed two warning lights popped up on my cluster: "4WD" and "ABS".
I'm from Italy, a country where you can't find any Skyline-experienced tuner, so I need some help to make a diagnosis :(
After searching on the net and on this forum I opened the trunk and watch for error codes on Attesa ECU:

-six slow flashes
-a short pause
-three fast flashes
-a long pause

After that the flashes looped the same pattern

Is it the "63" error code? (FR and RR G-Sensor 1 or 2 and circuit)

If so, I still don't know what does it mean and which parts I have to check to find out the problem...

May you help me, please?

Thank you

Have you checked the reservoir in the boot? Had the same thing a little while ago...low fluid.

on the battery, in the boot and in the engine bay. Pretty easy to find, any black cable the connects to the body. Have you had work done recently?
About 3 weeks ago the car had the coilovers changed...
I don't know if the problem may be related to this work :confused:

Check the wiring continuity from the G-sensor connector back to the Attessa ecu. At the same time check the g-sensor for the red stripe of death

I checked the level and it's about 2 centimeters above the max (cluster on, engine off)
Maybe I have to check it with engine running...
EDIT: The fluid in the reservoir seemed to be of two different colours... Is it a problem?

Where is the G-sensor? How can I identify it?
Red stripe of Death?:confused:

Two different colours are normal also a 5mm gap, check the reservoir when the ignition is on, I seem to remember that's when to check the level. Personally I use the level when the engine is running and I haven't had the warning lights on again.

During the weekend I performed several checks:

-G-sensor ok (no red stripe of death:chuckle: )
-Some sort of oxidation on the ATTESA ECU bracket (not on the ECU itself) but apparently there is no leaking from rear wiper
-ATF level on reservoir is slightly above max when the engine is on

As a last try I disconnected and reconnected ECU plugs: the warning lights disappeared :):thumbsup:

It was a problem of electric contact on the plug, probably because of the age of the car... I will also clean the plugs with a dry cleaner for electronic boards ;)

Thank you all guys for support :clap::cool:
