Principles of Operation

The anti-lock brake control module manages anti-lock braking with traction control and stability assist, also manages traction control and engine control systems to maintain vehicle control during deceleration and acceleration.

When the ignition switch is put in the RUN position, the module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the hydraulic pump motor is turned on for approximately one half-second. Any malfunction of the anti-lock brake control system will disable the traction control and stability assist and the anti-lock brake warning indicator will illuminate. However, the power-assist braking system will function normally.
