Principles of Operation: Notes

NOTE: The anti-lock brake system (ABS) module is part of the hydraulic control unit (HCU) and cannot be installed separately.

The ABS module controls the foundation brake function as well as anti-lock braking.

When the ignition switch is placed in the RUN position, the module carries out a preliminary electrical check. At approximately 20 km/h (12 mph), the hydraulic pump motor is turned on for approximately 0.5 second. Any malfunction of the ABS disables the ABS and the anti-lock brake warning indicator illuminates. However, the power-assist braking system still functions normally.
