Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Principles Of Operation
The ABS module, with or without stability assist, 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 put in the RUN position, the module carries out 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 disables the traction control and stability assist (if equipped) and the anti-lock brake warning indicator illuminates. However, the power-assist braking system will function normally.
