Anti-Lock Brake System (ABS): Notes
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module manages anti-lock braking, while the ABS module with stability assist manages anti-lock braking, traction control, and engine control systems to maintain vehicle control during deceleration and acceleration.
When the ignition switch is in the RUN position, the ABS module does a preliminary electrical check, and at approximately 20 km/h (12 mph), the hydraulic pump motor is turned on for approximately 1 half-second. Any malfunction of the ABS disables the stability assist and the ABS warning indicator illuminates. However, the power-assist braking system functions normally.
