ATTESA Codes-R33 GTR

[Sky32833]

the awd/abs lights are illuminated.

Codes: (I believe I counted the lights correctly on the attesa unit-maybe shed light on how to accurately read the codes?)

61-FR and RR G sensor 1 and circuit

63-FR and RR G sensor 1 or 2 circuit 

64-G sensor 1 power supply 

 

I checked the G sensor under the center console, and it looks good.

pulled / cleaned all ABS sensors- no luck. 
any help/better starting point would be awesome!

Sounds like that G sensor isn't plugged in.

Per the diagrams GTSBoy scanned, all wiring to the G sensor comes from the ATTESSA computer under the rear parcel shelf in the boot, 

pages CH-57 onwards in the 32 GTR manual cover trouble shooting the system, that is worth a read, but I'd start by removing the centre console and checking the G sensor is OK and plugged in correctly, and the wiring to it is not damaged. If it all looks OK you could check continuity between the G sensor and ATTESSA computer for those wires. In R32 it states 10A fuse #21 (4WAS) supplies power to that system

Did this issue happen suddenly or were you doing something prior?
