Section 80 (Anti-Lock Brake System): Operation
WARNING: This page is about a different car, the 1997 Mercury Mountaineer, 1997 Ford Explorer, and 1996 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
ABS control module receives an AC signal from each speed sensor. This information is translated into calculated wheel speed. When ABS control module determines wheel lock-up is about to occur, the appropriate solenoid valve is activated and deactivated to vary hydraulic pressure to prevent wheel lock-up.
ABS does not operate during normal braking conditions. ABS is self monitoring. ABS has a self-diagnostic system to obtain trouble codes for testing purposes. See DIAGNOSIS & TESTING .
CAUTION:
