Mariner 4WD V6-3.0L (2010)
Auxiliary Power Outlet: Description and Operation
High-Voltage Converter/Inverter
DC/DC Converter
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/DC converter is a liquid-cooled component that converts high-voltage (216-397 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 is controlled by the PCM and is located on the RF wheel housing.
DC/DC Converter Wiring Harness
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/DC converter wiring harness supplies high-voltage (216-397 volts) DC power to the DC/DC converter from the Electronically Controlled
Continuously Variable Transmission (eCVT). Like all other high-voltage wiring, it is orange in color. The DC/DC converter wiring harness runs along
the back of the engine underneath the engine cover and is a serviceable part.
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 underneath the floor console and is a serviceable part. The AC power point is located in the front of the floor console and can
be serviced separately from the floor console.
