Outlet, Power, 115 V: Operation: Operation
WARNING: This page is about a different car, the 2015 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.
The 115 volt AC power outlet switch receives 12 volts from the Power Distribution Center (PDC) and passes it as an enable signal to the inverter module. The inverter module also receives 12 volts via the PDC and inverts this to a 115 volt AC output. The inverter module sends a signal over the switch sense circuit advising the cluster that the outlet is active. The enable signal received from the power outlet switch enables the inverter to convert the received voltage and pass it to the power outlet to power external devices.
