CUSTOMER CONCERN
After right-front collision repairs and replacement of the right-front air spring, height sensor, and compressor, DTCs C1124:54 and B1041:52 return because the height-sensor calibration will not remain stored.
CAUSE
The confirmed repair identified a failed Air Suspension Control Module A (SUMA) that could not retain the height-sensor calibration after its power and ground circuits tested correctly.
CORRECTION
Remove and replace the failed Air Suspension Control Module A (SUMA), program the replacement module, perform the height-sensor calibration, clear DTCs C1124:54 and B1041:52, and verify suspension operation.
