Anti-Lock Brake System (ABS) Module

The ABS module is attached directly to the EBB unit and is the ECU for the ABS and stability control systems. The module monitors all sensor inputs and all CAN messages relating to ABS and stability control, then directly controls the solenoid valves and the hydraulic pump motor in the EBB unit. The ABS module can be serviced separately from the EBB unit. When a new ABS module is installed, the module must be programmed with the current vehicle configuration information. For additional information on module programming, Refer to: Module Configuration - Electric - System Operation and Component Description .

When an ABS or stability control fault has been corrected or a new component has been installed, the ABS module must be calibrated using the ABS Calibration routine found on the diagnostic scan tool. ABS Calibration is required for the stability control sensors to learn the zero-position of the vehicle which means the vehicle must be on a level surface and not moving.
