Low Fuel Indicator

This is a distributed function between the Body Function Controller (BFC) and the Instrument Cluster. The Low Fuel indicator (amber) will be turned ON to indicate to the driver that the fuel level has dropped to a calibrated point below 1/8 of a tank. The indicator is turned OFF when the fuel level rises back above 1/4 of a tank. The fuel level is determined from the Fuel Level Sense and Display function and is then used in this function. The Body Function Controller (BFC) will determine the indicator control and then send the control state to the Instrument Cluster in the Serial Peripheral Interface (SPI) serial data message. The Instrument Cluster will read the Low Fuel indicator control state in the Serial Peripheral Interface (SPI) message and control the indicator directly.
