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 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 "TRAC OFF" and "TRAC ACTIVE" lamps flashing. The lamps will flash after the clearing of DTC's that are indicated on the stability assist 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 as well as the configuration procedure must be carried out. For additional information regarding the module configuration procedure, refer to MODULE CONFIGURATION .
When carrying out the lateral accelerometer or yaw rate calibration with the scan tool, the vehicle must be on a level surface, not moving, with ignition switch in the RUN position. When carrying out the booster learn cycle on the scan tool, the ignition switch must be in the RUN position with the engine running and the brake pedal must not be applied. When carrying out the steering wheel rotation sensor calibration with the scan tool, the ignition switch must be in the RUN position with the engine running and the steering wheel must be rotated back and forth from lock position to lock position.
