System Operation

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The accessory AC/DC power control module receives fuse protected battery voltage and is connected to the 12 volt electrical system ground. The accessory power outlet has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON, and a 120 volt AC powered device is plugged into the accessory power outlet, the normally open switch in the accessory power outlet, closes. When the accessory AC/DC power control module detects the voltage from the accessory power outlet switch, the inverter module begins to supply 110-120 volts AC to the accessory power outlet after a 1.5 second delay. An LED indicator in the accessory power outlet illuminates when the outlet is receiving AC voltage. The accessory AC/DC power system is protected against circuit overload and circuit shorts to ground.
