ABS Module Calibration

The ABS module should be configured before it is calibrated. The ABS module must be calibrated if any of the following is occurring or has occurred:

• A new ABS module has been installed
• A new HCU has been installed
• A new stability control sensor cluster is installed
• A new steering wheel rotation sensor is installed
• The stability/traction control indicator "sliding-car icon" flashes once every 2 seconds
• DTC C1991 is present in the ABS module

Calibration is required for the ABS module to learn the "at rest" or "zero" position of the ESC components. If a DTC is present for any ESC specific component(s), the DTC must be repaired and cleared before carrying out the calibration procedure. The sliding-car icon will flash after clearing the DTCs that are associated with the ESC system.

To carry out the calibration procedure, connect the scan tool, proceed to the IVD Initialization sequence and follow the scan tool instructions. If a DTC is retrieved after calibration, refer to the ABS Module DTC Chart.
