Traction Control Module: Service and Repair

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 at Brakes and Traction Control/Testing and Inspection. 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 re-calibrate the stability assist module is also indicated by the active/fail lamp flashing. The lamp will flash after the clearing of DTC's that are indicated on the stability assist module calibration list. If a DTC is retrieved after recalibration; refer to the Stability Assist Module DTC Index at Brakes and Traction Control/Testing and Inspection. If installing a new stability assist module, the calibration procedures as well as the configuration procedure must be carried out.

When carrying out the dual axis acceleration or yaw velocity calibration on 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 on 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.
