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: Notes
The anti-lock brake system (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. The ABS accomplishes this by communicating with the other modules over the high speed controller area network (HS-CAN) bus.
When the ignition switch is 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 system disables the traction control and stability assist (if equipped). The ABS module communicates with the instrument cluster over the HS-CAN bus and the cluster illuminates the anti-lock brake warning indicator. However, the power-assist braking system functions normally.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
