Fuel Gage

WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.

The instrument panel cluster (IPC) displays the fuel level as determined by the PCM/ECM. The IPC receives a serial data message from the PCM/ECM indicating the fuel tank level remaining. The fuel gage defaults to empty if the PCM/ECM detects a malfunction in the fuel level sensor circuit or the IPC detects a loss of serial data communication with the PCM/ECM.

When the fuel level is below a pre-determined value, the low fuel indicator/message is displayed in the IPC.
