WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module internally monitors the hydraulic control unit (HCU) internal pressure and the hydraulic brake pressure to each wheel. If the pressure drops below acceptable limits, the ABS module sets a DTC and the red brake warning indicator and ABS light illuminate.
Possible Causes
- Base brake system leak
- HCU
