Normal Operation

WARNING: This page is about a different car, the 2003 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The electronic parking brake (EPB) two-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 applies, circuit 32-CG19 (WH/VT) is equal to battery voltage and circuit 33-CG19 (YE/VT) is equal to zero volts. When the EPB releases, 32-CR19 (YE/VT) is equal to zero volts and 33-CT19 (YE/VT) is equal to battery voltage. Otherwise both circuits are at one half of battery voltage.
