Fuel Gage

The IPC displays the fuel level as determined by the PCM. The IPC receives a Glass 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:

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

When the fuel level is less than a pre-determined value, the low fuel indicate illuminates.

Reviewing the fuel system description will further explain how the system functions.
