Low Fuel

The driver information center (DIC) displays the low fuel message as determined by the engine control module (ECM). The ECM monitors the fuel level sensor signal and will request the LOW FUEL message from the body control module (BCM) when the fuel level is less than 14 percent. The DIC receives a GMLAN message from the BCM requesting display of the LOW FUEL message.

The instrument panel cluster (IPC) displays the low fuel indicator as determined by the engine control module (ECM). The ECM monitors the fuel level sensor signal and will request the LOW FUEL indicator from the body control module (BCM) when the fuel level is less than 14 percent. The IPC receives a GMLAN message from the BCM requesting display of the LOW FUEL message.
