ABS Module Calibration

When a new ABS module, HCU, or RCM is installed, the ABS module must be calibrated. The calibration procedure is required for the ABS module to learn the zero-position of the various ESC sensors and components.

If a DTC sets for any component of the ABS or AdvanceTrac® system, correct the fault condition and clear the DTC before carrying out the calibration procedure. The need to calibrate the ABS module is also indicated by the sliding car icon in the IPC flashing once every 2 seconds. The indicator flashes after clearing the DTCs associated with the ABS or AdvanceTrac® system.

To calibrate the ABS module, carry out the IVD Initialization sequence using the scan tool.

If a DTC is retrieved after calibration, refer to the ABS Module DTC Chart .
