Low Fuel

The low fuel indicator is a LED display is that is located in the instrument cluster. The low fuel indicator will turn ON for 3 seconds when the ignition switch is turned to the RUN position. When the ignition switch is in the RUN position, the VCM/PCM constantly sends a Percent of Fuel Remaining message over the class 2 serial data line to the instrument cluster in order to display the appropriate fuel level. The instrument cluster uses the fuel level information from the PCM/VCM in order to operate the fuel gauge. The information is also used in order to determine when the low fuel indicator should be turned ON.
