The Anti-lock Brake System (ABS) module simultaneously manages the anti-lock braking, traction control and engine control systems to maintain vehicle control during deceleration and acceleration.
When the ignition switch is in the RUN position, the module carries out a preliminary electrical check and, at approximately 12 mph (20 km/h), the hydraulic pump motor is turned on for approximately one half-second. Any malfunction of the anti-lock brake system disables the traction control and stability assist (if equipped) and the anti-lock brake warning indicator illuminates. However, the power-assist braking system functions normally.
The Anti-lock Brake System (ABS) consists of the following components:
