Anti-Lock Brake System Control Module
Anti-Lock Brake System (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 also provides proportioning valve function. 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.
