Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module, Power Inverter: Operation
Once an item is plugged into the Alternating Current (AC) power outlet, or if equipped with an enable touch switch and it is actuated, the voltage input request to supply voltage to the power outlet is performed. The Body Control Module (BCM) sends an enable signal and voltage to the Power Inverter Module (PIM). The PIM converts this 12v input to a 115v AC output for NAFTA vehicles or 230v AC for BUX vehicles. The PIM then supplies the AC voltage to the power outlet.
Power remains active until one of the following events occur (normal operation):
- The item has been removed from the power port.
- The AC power outlet switch (if equipped) has been cycled to the off position.
- The ignition is in the OFF position and load shedding has timed out.
A device plugged into the outlet can overload the inverter. High startup current requirement that may be 5 to 10 times the operating current will trigger a fault and the inverter will think it is a short and shut down. Motors and power units with a lot of input capacitance will cause this.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
