See ANTI-LOCK BRAKE SAFETY PRECAUTIONS
article in GENERAL INFORMATION.
The Anti-Lock Brake System (ABS) control module senses reductions in front and rear wheel speed and modulates hydraulic pressure to the brakes to prevent wheel lock-up. The ABS consists of a hydraulic unit, 4 wheel speed sensors and sensor rotors, valve relay, motor relay, pump motor, "G" sensor (4WD only) and ABS control module. See Fig 1 . An ABS warning light is located on instrument cluster.
