Anti-Lock Brake System - With Traction Control: Description
NOTE:
This article contains information regarding ABS system equipped with the optional TRAC (traction control) system. For diagnostic information pertaining specifically to TRAC system, see appropriate TRACTION CONTROL article.
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, Electronic Control Unit (ECU), and a speed sensor at each wheel. If a system fault occurs, the 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 or Fig 2 .
