Section 3 (Anti-Lock Brake System): Operation
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 1993 Mercury Sable, 1993 Lincoln Continental, 1993 Ford Taurus, 1992 Mercury Sable, and 1992 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
The ECU receives and processes 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 hydraulic pressure to the system. The ABS incorporates self-diagnostic capabilities. See Fig 1 . See DIAGNOSIS .
