Suspension error code

At startup i get code C1B18-62 (6C) " Supply voltage x-ref check - Algorithm based failure - signal compare failure on my gap tool along with the orange dash light which goes out approx. 30 secs-1min later and car is down evenly at the front slightly, i cant find any reference to the code so i can pinpoint the issue. Possibly front or central valve block ?

That code shows up as:

Inconsistent battery voltages received by Air Suspension control module.

Air suspension control module supply short circuit to ground.

Air suspension control module supply short circuit high resistance

Air suspension control module failure.

Firstly I'd check the battery voltages and connections especially the earth strap to body, they are known to cause issues.

I know they are all good, not so much an issue down here. I do have a Llams suspension controller fitted which may have come adrift so i'll start there.
