I have a 2007 cadillac escalade esv AWD. Aweek ago we changed the front shocks and the the air compressor. Since then service suspension system comes on and off. Scan tool says no codes. My mechanic is at lose, what gives?
If that light is on, there will be codes stored, you need to have a scanner with the capabilities to read chassis codes such as a tech 2 scan tool and start your diagnoses there, could be a level sensor, or maybe the incorrect shocks where installed.
