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.
Power Inverter Module (PIM)
| Refer to COMPONENT INDEX . |
The PIM is located in the instrument panel behind the Radio. This device that converts 12 volt Direct Current (DC) to 115-volt Alternating Current (AC). The AC current can be used to supply small appliances. The PIM receives a 50a fuse protected power feed from the interior PDC. The PIM output voltage for North American (NA) vehicles is 115-volt is a modified sine wave. The PIM can supply up to 400 watts of continuous output power if the input 12-volt side has sufficient capacity. The 400 watt PIM has two separate outputs:
- One output drives both of the interior outlets simultaneously
- One output drives the exterior RAM BOX outlet independently
These two outputs operate independently of each other. The interior outlet output powers up both interior outlets when one outlet is used.
The BCM activates an internal 12-volt inverter control line relay when the ignition state is ACC or RUN. This control line is also active during the accessory delay. The inverter senses the presence of a plugged-in device by closing an internal mechanical switch. When plugged-in, the inverter will activate its inverter enabled signal and send this signal to the BCM. The BCM receives this signal and then sends a bus message to the IPC for an indication display.
The BCM can disable the inverter if the battery is at a critical state, if the vehicle is in load shedding state, or if the vehicle has entered shipping mode.

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.
