Anti-Lock Brake System: Operation

A REAR ANTI-LOCK indicator light, located in instrument cluster, comes on for 3 seconds as a bulb test when ignition is first turned on. A primary check is performed after each engine start, and the first time vehicle speed exceeds 4 MPH. If brake pedal is pressed before vehicle exceeds 4 MPH, primary check will not occur until brake pedal is released.

Under normal driving conditions, ABS functions like a standard brake system. Upon detection of wheel lock-up, short pedal pulsations will occur. Pedal pulsation will continue until there is no longer a need for anti-lock function.
