Traction Control: Anti-Lock: Description
Anti-Lock Brake System (ABS) controls brake fluid pressures to each individual front brake caliper and rear brake calipers during a panic stop to prevent wheel lock-up. System consists of actuator, solenoid relay, pump motor relay, ABS/Traction Control/Vehicle Skid Control Electronic Control Unit (ABS/TRAC/VSC ECU), and a speed sensor at each wheel. See Fig 1. Vehicle is equipped with TRAC and VSC. The ABS and TRAC system helps vehicle stability during braking and acceleration. VSC system helps vehicle stability during cornering. If a system fault occurs, the ABS/TRAC/VSC ECU stores a Diagnostic Trouble Code (DTC) that can be retrieved to diagnose malfunction.
