ABS Module Calibration

When a new ABS module, HCU  , RCM  or steering wheel rotation sensor 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  /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 stability/traction control indicator "sliding-car icon" in the IPC  flashing once every 2 seconds. The indicator flashes after clearing the DTCs that are associated with the ESC  /RSC®  systems.

To calibrate the ABS module, carry out the IVD Initialization sequence using the scan tool. When carrying out the calibration procedure, the vehicle must be on a level surface and must not be moving. If a DTC is retrieved after calibration, refer to the ABS MODULE DTC CHART  in this information.
