WARNING: This page is about a different car, the 2008 Jeep Patriot and 2008 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
The AC power outlet receives 12 volts from the Totally Integrated Power Module (TIPM) and passes it as an enable signal to the inverter module. The inverter module also receives 12 volts via the TIPM and inverts this to a 110 volt AC output. The enable signal received from the power outlet enables the inverter to convert the received voltage and pass it to the power outlet to power external devices.
