Switch For Opening The Fuel Tank Filler Cover
The switch for opening the fuel tank filler cover is on the light switch module (LSM) (3/111). The light switch module (LSM) is serially connected to the central electronic module (CEM) via LIN. The cover can be opened if the vehicle speed is below 7 km/h (5 mph).
For the American market, the function has a delay before the fuel tank filler cover can be opened. This is to allow for the cancellation of the automatic leak test and for the pressure in the tank to even out.
