Hello,

I would have a look at the Measuring Value Block group [002], field (1) is current the Voltage supply value as seen by the controller. This value needs to reflect the current battery voltage (+/-1.0V) of the vehicle, if the voltage is correct, it sounds like there could be a concern with the J492-All Wheel Drive Control Module.

Also we have a Ross-Tech wiki page for the 00532 - Supply Voltage B+: Signal too Low


Hope this helps,

drpeter

I do have my work cut out for me!
I have ordered the SAIR selenoid and a new connector for the wheel sensor.

The A/C and the door and the air bag I have not started to look at yet.

Twisted pair for W-CAN might be dropped out from ABS to AWD controller due to gateway in cluster being FUBAR.

01305 - Databus for Infotainment
37-00 - Faulty

I suspect that is due to an aftermarket radio being installed.

the voltage at battery is 12.4 (on a trickle charger)
Measuring Value Block group [002], field (1) shows 12.3
measuring at connector it is 12.3 pin 2-3 on the harness side.

I also did an oil and filter change and the oil came out looking clean and the filter was not dirty.
