Just reporting back guys, 4 weeks since I've replaced the caps and did the voltage adjustments.
One pot I could only get to 2.4V but its all good, no longer sends a error code to the ATTESSA ECU. So ABS and 4WD lights have been off the whole time and have been enjoying the safety of 4wd in this horrid sydney weather.
Big thanks to Jeff and Peter good shit. One question, do you know what are the implications of a 2.4V signal instead of 2.5V? would it result in less front torque split or anything like that?
I will work on replacing that adjustment pot in the future I think. Thanks again.
SiR RB - take a look at the 1st post where Jeff (Datsun_1600) posted a facebook link to a picture, that is how u measure the voltage and you adjust by spining the round things. Start with that man, if you can get a hold of a GTR service manual it will tell u which plug u measure going into the ECU... but looks like the G sensor is the weak point, so do that 1st.
