    Your car has its own built-in code reader/scanner/memory for Diagnostic Trouble Codes. Study the sticky post ^^^ "How to pull codes. Practice, write any codes down, and note whether each is Current or History. Return to the sticky and open the link with "obd2" in the address - this will take you to a Master Index of all P,B,C, and U codes. Decipher your codes, write it all down and post it all here.

    You're looking for Level Control codes - there is no "air suspension". The only function of the shock bladders is load control - and that's done with a compressor, control solenoid, height sensors, air lines, and bladders. The compressor may have failed due to moisture - the filter/dryer tends to load up with snot created by air compression. If that's the case you can look at the Suncore site or talk to Chris in Parts at Rippy Cadillac over there >>>> The compressor assembly is up in the RR fenderwell inside the plastic liner. If a height sensor fault shows up it's either the sensor itself or the control arm link may be disconnected. Suspension arm to frame.
