Low Fuel

The low fuel telltale is a LED display is that is located in the IPC. The low fuel telltale is operated by the IPC with software control. The low fuel telltale will turn ON for 3 seconds when the ignition switch is turned to the RUN position. The VCM/PCM constantly sends Class 2 messages that inform the IPC of the fuel level when the ignition switch is in the RUN position. The IPC uses the Class 2 fuel level information in order to operate the fuel gauge. The information is also used in order to determine when the low fuel telltale should be turned ON.
