Anti-Lock Brake System (ABS) controls brake fluid pressures to each individual front and rear brake caliper during a panic stop to prevent wheel lock-up. System consists of actuator, solenoid relay, pump motor relay, Anti-Lock Brake System/Traction Control/Electronic Control Unit (ABS/TRAC ECU), and a speed sensor at each wheel. If a system fault occurs, ABS/TRAC ECU stores a self-diagnostic code(s) that can be retrieved to diagnose malfunction. Some models are equipped with an optional Traction Control (TRAC) system, which is integrated with the ABS system. See Fig 1.
