Control Module Calibration

Important: New Continuously Variable Road Sensing Suspension (CVRSS) control modules must be calibrated after installation. A code C1658 is stored in the memory of new CVRSS control modules and will not clear until the module is calibrated.

1. Make sure the scan tool has latest version chassis application program.
2. Connect the scan tool to Data Line Connector (DLC).
3. Ignition "ON," engine off.
4. Proceed per instructions on the scan tool readout.
5. After calibrating CVRSS control module, "ELC Trim Height Adjustment" and "Steering Autocenter Adjustment" procedures must be performed.
