ABS Module Calibration

NOTE: When installing a new ABS module, HCU or steering wheel rotation sensor, the ABS module must be calibrated. The installation of a new Stability Control Sensor Cluster does not require ABS module calibration.

If installing a new ABS module, the calibration procedures must be carried out. For module calibration, follow the scan tool directions. The calibration procedure is required for the ABS module to learn the "zero-position" of the various roll stability control (RSC) sensors and components.

If a DTC is logged for any component of the roll stability control system, the DTC must be cleared before carrying out the calibration procedure. The need to calibrate the ABS module is also indicated by the stability control/traction assist indicator on the instrument cluster module flashing once every 2 seconds. The indicator flashes after clearing the DTCs that are associated with the RSC system. If a DTC is retrieved after calibration, refer to the Anti-Lock Brake System (ABS) Module Diagnostic Trouble Code (DTC) Chart.

When carrying out the calibration procedure for the ABS module, the vehicle must be on a level surface, must not be moving and the ignition switch must be in the RUN position.

When carrying out the calibration procedure for the ABS module after installing a new steering wheel rotation sensor, 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.
