Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The electronic parking brake (EPB) 2-way motor receives power from circuit 32-CG19 (WH/VT) or 33-CG19 (YE/VT), depending on the direction of the motor revolution. When the EPB is applied, circuit 32-CG19 (WH/VT) is equal to the battery voltage and circuit 33-CG19 (YE/VT) is equal to 0 volts. When the EPB is released, 32-CR19 (YE/VT) is equal to 0 volts and 33-CT19 (YE/VT) is equal to battery voltage. Otherwise, both circuits are at one half of the battery voltage.
