Fusion FWD L4-2.5L Hybrid (2010)
Auxiliary Power Outlet: Description and Operation
High-Voltage Converter/Inverter
DC to DC Converter Control Module (DC/DC)
WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to
depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its
components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage
components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious
personal injury or death.
The DC to DC Converter Control Module (DC/DC) is a liquid-cooled component that converts high-voltage (179-343 volts) DC power from the High
Voltage Traction Battery (HVTB) to low-voltage (12 volts) DC power. This charges the 12-volt battery through the low-voltage battery cables and
powers the low-voltage electrical systems, eliminating the need for a conventional engine-driven generator. It utilizes a dedicated control module, which
is part of the DC/DC. The DC/DC communicates with other modules over the High Speed Controller Area Network (HS-CAN) bus, and is located on the
RH frame rail, behind the radiator support.
High-Voltage Cable Assembly
WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to
depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its
components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage
components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious
personal injury or death.
All cables that carry high voltage are integrated into a single high-voltage cable assembly that runs between the DC/DC, the Electronically Controlled
Continuously Variable Transmission (eCVT), the Air Conditioning Compressor Module (ACCM) and the HVTB. The high-voltage cable assembly can
be serviced separately from the rest of the high-voltage system.
DC/AC Inverter and AC Power Point
The DC/AC inverter converts low voltage (12 volts) DC to 110 volts AC to power a device that uses AC power with a rating of less than 150 watts. The
DC/AC inverter is located behind the RH rear seat bolster, and is a serviceable part. The AC power point is located in the rear of the floor console and
can be serviced separately from the floor console.
