Anti-Lock Brake System: Operation: Notes

An ABS warning light, located on instrument panel, comes on for 3 seconds as a bulb test when ignition is turned on. A primary check is performed after each engine start and initial time vehicle speed exceeds 4 MPH. An actuator noise will be heard as vehicle speed exceeds 4 MPH (this is normal). If brake pedal is depressed before vehicle speed exceeds 4 MPH, the primary check will not occur until brake pedal is released.

Under normal driving conditions, ABS functions like a standard brake system. When wheel lock-up is detected, brake pedal may pulsate and steering wheel and vehicle body may vibrate (this is normal). Pulsation or vibration will continue until ABS function is no longer needed or vehicle is stopped. Maintaining a constant force on brake pedal provides shortest stopping distance.
