Fuel Filler Door Release

The BCM sends a voltage signal to the fuel filler door release switch. When the switch is pressed, the signal is routed to ground, indicating a request to release the fuel filler door latch.

When the BCM detects the fuel filler door release switch is pressed, it sends a message to the PCM over the CAN to release the fuel filler door latch. The PCM checks the fuel tank for excessive fuel vapor pressure. If excess fuel tank vapor pressure is detected, the PCM activates a pump to remove the excess pressure.

When the PCM detects the excess pressure is removed, it provides a ground for the fuel filler door release relay, energizing the relay. The relay provides voltage to activate the fuel filler door release solenoid, releasing the fuel filler door latch. The process to release the fuel filler door can take as long as 15 seconds.

In the event the electronic fuel filler door release system fails, the fuel filler door latch can be released manually using the manual fuel filler door release cable. The manual fuel filler door release cable is located in the luggage compartment.
