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 (Abs) Control Module
ABS uses a Controller Anti-Lock Brake (CAB) module. CAB module monitors wheel speeds to modulate hydraulic pressure in each brake channel, when ABS or traction control are activated to prevent wheel lockup under severe braking conditions to provide improved vehicle control. CAB module also provides vehicle speed signal to Powertrain Control Module (PCM). CAB module communicates with other modules via the Programmable Communication Interface (PCI) bus circuit. For additional information on ABS, see appropriate ANTI-LOCK article in BRAKES.
