Optimized Hydraulic Braking (3.0L All-Wheel Drive (AWD) and 3.5L only): Notes
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Optimized hydraulic braking is a system built into the ABS module to aid in bringing the vehicle to a safe, controlled stop in the event of severe vacuum loss at the brake booster. The ABS module continually monitors the vacuum in the brake booster through the use of a sensor. If a loss of vacuum is detected, the ABS module will activate the pump motor in the HCU to assist with vehicle braking.
