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.
Anti-Lock Brake System Module
Anti-Lock Brake System (ABS) is referred to as a Controller Anti-Lock Brake (CAB) module. CAB module monitors Wheel Speed Sensor (WSS) inputs continuously while vehicle is in motion to modulate hydraulic pressure in each brake channel. ABS is activated to prevent wheel lockup under severe braking conditions to provide improved vehicle control. CAB module communicates with other modules through CCD bus circuit. See CCD BUS CIRCUIT . For additional information on ABS, see appropriate ANTI-LOCK article in BRAKES.
