Air Suspension Failure

[timdo1]

Hi All,

I had my transmission rebuilt. On the cars return, the suspension has failed.

Here are the fault codes

Suspension

C1A00-53 (AF) Control module - System programming failure - deactivated
( on 06-04-2022 09:47:17 at 322290 km )

C1A00-54 (AF) Control module - System programming failure - missing calibration
( on 06-04-2022 09:52:58 at 322290 km )

I have a small leak in my front suspension so over night its going down. To get it back up I have to re-calibrate the corners before I can drive it. I have no up or down control inside the car and no special programs. Ive crawled underneath the car and cant see any loose wires. It wasnt like this when it went in.

The question is, what am I missing. What is the likely culprit? It seems odd that it was all working fine, and a rebuilt transmission could do this?

Looking for ideas on where to search please.

I should add, I also have no heat or cool. Cooling was re-gassed prior to Xmas and worked fine through the period, but stopped working in Jan. Back air con works fine but front comes and goes. Interestingly enough, when I re-calibrated the transfer case yesterday (wondering if that is why the suspension had failed) the air con came on and worked until I next started the car.

I also took the instrument cluster out tonight and checked the connector at the back just in case. Could see nothing wrong.
