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 SASM  has been 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 stability control components. If a DTC is set for any stability control component, the DTC must be cleared before carrying out the calibration procedure. The stability/traction control indicator will flash after clearing the DTCs that are associated with the stability control system. If a DTC is retrieved after calibration, refer to the ABS MODULE DTC CHART .

To calibrate the ABS module, carry out the IVD Initialization sequence. Follow the instructions provided by the scan tool.
