Suspension Control Module: Service and Repair

Removal and Installation

1. CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

Disconnect the battery ground cable.





2. NOTE: The air suspension control module is mounted to the lower left side of the dash above the parking brake control.

Disconnect the electrical connectors.





3. Pull back the dash padding to expose the module mounting nuts.





4. Remove the air suspension control module nuts.

5. NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 mi) or more to relearn the strategy.

NOTE: The air suspension control module is calibrated with information from the ride height sensor. A new or exchanged air suspension control module requires that the ride height adjustment calibration and pneumatic test be carried out. For additional information, refer to Calibration Initialize System-Clear C1990 and C1991 DTCs.

To install, reverse the removal procedure.
