Low Fuel
WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
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.
