Anti-Lock Brake System W/O Traction Control: Description

Anti-Lock Brake System (ABS) consists of an actuator, control relay (solenoid relay and motor relay), ABS Electronic Control Unit (ECU), and 4 wheel speed sensors. ABS ECU and relay are part of actuator assembly. See Figure.

An ABS indicator light is located on the instrument cluster. Indicator light comes on for 3 seconds as a bulb test when ignition is turned on. A primary check is performed after each engine start, and when initial vehicle speed exceeds 6 MPH. If brake pedal is pressed before vehicle speed exceeds 6 MPH, primary check will not occur until brake pedal is released.
