Stability Assist Module Calibration

The stability assist module needs to be recalibrated whenever a component specific to the stability assist system is disconnected, moved, or a new component is installed. For additional information regarding the DTCs that require the recalibration procedure, refer to the STABILITY ASSIST MODULE CALIBRATION  List. If a DTC is logged for any component of the stability assist system, the DTC must be cleared before carrying out the recalibration procedure. The need to recalibrate the stability assist module is also indicated by the active/fail lamp flashing after the clearing of DTCs that are indicated on the Stability Assist Module Calibration List. If a DTC is retrieved after recalibration; refer to the STABILITY ASSIST MODULE DIAGNOSTIC TROUBLE CODE (DTC) INDEX . If installing a new stability assist module, the calibration procedures must be carried out.
