Optimized Hydraulic Braking (3.0L All-Wheel Drive (AWD) and 3.5L only)

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.

When the vacuum sensor in the booster indicates vacuum is below a predetermined level, a DTC will be set in the ABS module. A low vacuum DTC will be set after a pre-determined time, depending on driving conditions. It could take as long as 10 minutes to set the DTC with vehicle speed above 2 km/h and greater than 30% throttle. If the brake pedal is applied with low vacuum in the booster, the ABS module will activate the pump motor in the HCU to assist with braking.

Refer to POWER BRAKE ACTUATION for sensor removal and installation information.
