ENR34

After some time driving my ENR34 sedan with RB25DET NEO6 engine, I had finally been able to resolve some AWD problems, mostly wiring incompatibilities in the stock looms of the ER34 GTT engine ecu and ENR34 body loom. I had also now managed to get power to the ATTESA ecu, and put it in diagnosis mode, which gave me some codes. I had expected that the codes listed in the English R34 supplement manual for my model would be correct, but then it had also told me to look for lights on top of the ABS/ETS (ie ATTESA) ecu, but in my sedan there were no lights. Diagnosis gave me these codes initially: 12 61 72 63 According to the manual this meant : 12 - front left inlet solenoid valve and circuit 61 - G sensor 1 and circuit 72 - nope there is no 72 63 - G sensor 1 or 2 and circuit Well that was odd, I was confused by a code 72, which wasnt even in the manual. And the G sensors and wiring hadn't been touched. A strange set of codes. Wondering if something was wrong with...

So, after a long story of fixing my ABS/ETS wiring issues, I had a functioning ATTESA ETS control unit at last. But things were not quite right with the whole system, so I ran the control unit diagnostics. How to run diagnostics on an R34 ATTESA ETS My car is a GT FOUR sedan, so a little different to a BNR34 GTR, but mostly the same. It seems the procedure is slightly different depending on whether your ATTESA ECU has visible lights on top, which flash diagnostic codes, or if no lights, the ABS dash light can flash codes when in diagnostic mode. You can put the ATTESA ECU into diagnosis mode using the grey Consult plug which is on the panel under the steering wheel, near the bonnet release handle. The plug is on the back of a trim piece that has a clip on one side. Now strangely enough I had to diverge from the English language R34 Service Manual for this procedure. The manual says to observe flashing lights on the top of the ATTESA ECU, which is in the boot/trunk behind the r...
