  Q: How to service and repair the Air Suspension Compressor for automatic level control air replacement on Cadillac DTS?

  A: Service and repair of the Air Suspension Compressor assembly requires a vehicle lift while maintaining vehicle support. The air suspension system must be depressurized but service personnel should never detach any air supply pipe to minimize the risk of injury to themselves or damage to the vehicle. Begin by marking the air hose locations prior to disconnecting them from the intake Air Filter and Air Suspension Compressor to preserve ecas (Electronically Controlled Air Suspension) system integrity. During cleanup of each component, remove both control solenoids and electrical connectors from air tubes as well as compressor assembly units. First, fully support the Air Suspension Compressor assembly while removing mounting nuts and bolts from the frame where the air intake filter sits. You need to remove the Air Suspension Compressor assembly from the vehicle. You should install the Air Suspension Compressor assembly into the vehicle first followed by mounting the nuts and bolts and tightening them to 9 n.m (80 lb in). After reattaching the Air Suspension Compressor filter to its frame, position the electrical connectors into place then route the right and left air tubes to the control solenoids. Pressurize the air suspension system before performing a vehicle lowering operation after restoration.
