Low Fuel Indicator

The amber low fuel indicator turns on in order to indicate to the driver that the fuel level has dropped to a calibrated point below 1/16 of a tank. The indicator is turned off when the fuel level rises back above 1/16 of a tank. The fuel level is determined from the fuel level sense and display function and is then used by the low fuel indicator. This is a distributed function between the PCM and the instrument cluster. The instrument cluster reads the low fuel indicator control state in the Class 2 message and controls the indicator directly. If a Class 2 data link fails, the low fuel indicator does not illuminate unless the indicator was illuminated prior to the Class 2 data link failure.
