Accessory DC Power Control Module Description and Operation: Location

The 14 V power module, also called the accessory DC power control module, is located in the rear trunk compartment underneath the floor stowage trim panel. It is attached to the chassis with four fasteners. The 14 V power module is cooled with pre-mixed Dexcool® circulating through a cooling system that is separate from the engine cooling system.

The 14 V power module is an electronic device that takes the place of the generator on a traditional vehicle. On a hybrid or electric vehicle the 14 V power module converts high voltage (300 V) direct current (DC) to low voltage (12 V) DC for accessory electrical operation and to charge the 12 V battery.

Normally, the 14 V power module only supplies 12 V DC when the vehicle is under a normal drive cycle. However there are certain instances when the vehicle is being charged through a standard wall socket where the 14 V power module operation is required to sustain the 12 V battery.

The 14 V power module is capable of supplying up to 130 Amps of 12 V DC.
