ABS Module Calibration

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 ESC/RSC sensors and components.

If a DTC is logged for any component of the ESC/RSC system, the DTC must be cleared or repaired before carrying out the calibration procedure. The need to calibrate the ABS module is also indicated by the RSC 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 ABS Module DTC Chart. ABS Module 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.
