WARNING: This page is about a different car, the 1997 Mercury Grand Marquis, 1997 Ford Crown Victoria, 1996 Mercury Grand Marquis, and 1996 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
ABCM receives a wheel speed signal from each wheel sensor. When wheel lock-up is about to occur, the ABCM activates solenoid valves to modulate hydraulic pressure to each wheel. A pump/motor assembly provides constant hydraulic pressure to the system. The ABS incorporates self-diagnostic capabilities.
