Fuel Gage

The engine control module (ECM)/powertrain control module (PCM) sends fuel level percent to the instrument panel cluster (IPC) via class 2. The IPC displays the fuel level as determined by the ECM/PCM. The fuel gage defaults to E (empty) if:

• The ECM/PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM/PCM.

When the fuel level is less than 10 percent, the LOW FUEL message illuminates.
