Low Fuel

The low fuel indicator is a LED on the fuel gage. The IPC illuminates the low fuel indicator in the following situations:

• The IPC determines that the fuel level is less than a pre-determined value. The IPC receives a signal from the BCM via the serial peripheral interface (SPI) indicating the fuel level.
• The BCM detects a loss of class 2 communications with the PCM.
• The IPC detects a loss of SPI communications with the BCM.
• The PCM detects a malfunction in the fuel level sensor circuit.
