WARNING: This page is about a different car, the 1995 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
ECU receives a wheel speed signal from each wheel sensor. When wheel lock-up is about to occur, the ECU 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.
