Fuel System Message Displays

The IPC  provides a check fuel fill inlet message to warn the driver there is a problem with the fuel fill inlet pipe resulting from a significant evaporative emission leak following vehicle refueling.

On the PHEV  , the IPC  provides a message to inform the driver the engine needs to run to maintain fuel freshness and a message to inform the driver why the fuel door is locked shut until the fuel evaporative emissions system equalizes pressure. This is to prevent rapid equalization since the fuel system can be under emissions-related vacuum or pressure during operation. The warning provides the reason the fuel door is locked while the fuel system allows the system to gradually equalize.

The IPC  receives the check fuel fill inlet message request, the refuel system status display message and the fuel maintenance mode display from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN). The GWM  receives the check fuel fill inlet message request, the refuel system status display message and the fuel maintenance mode display from the SOBDMC  over the High Speed Controller Area Network 1 (HS1-CAN).
