Anti-Lock Brake System (ABS) Module - Vehicles with Vacuum Brake Boost

WARNING: This page is about a different car, the 2022 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The ABS module is attached to the HCU and is the ECU for all of the ABS and stability control systems. The ABS 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 HCU.

The ABS module is service as an assembly with the HCU. When a new ABS and HCU assembly is installed, they must be programmed with the vehicle configuration information. Refer to: Module Configuration - System Operation and Component Description .

When an ABS or stability control system fault has been corrected or a new component has been installed, the ABS module must be calibrated. The calibration procedure is required for the stability control sensors to learn the zero-position of the vehicle. The calibration procedure requires the vehicle to be on a level surface and not moving. The calibration procedure (IVD Initialization) is carried out using a diagnostic scan tool.
