Fuel Gage Position - Range 0 - 250 Counts

This data indicates what message is being sent from the Body Function Controller (BFC) to the Instrument Cluster to control Fuel Gage Pointer position. The Body Function Controller (BFC) reads the Fuel Level Sensor value in ohms, filters it to prevent fuel gage slosh, and sends fuel level information on the Serial Peripheral Interface (SPI) data line in counts to the Instrument Cluster. The cluster then drives the fuel gage pointer. The fuel gage Serial Peripheral Interface (SPI) count value to fuel gage (pointer) position ratio is as follows:

The Body Function Controller (BFC) also transmits Class 2 serial data fuel messages to the Powertrain Control Module (PCM) for OBDII purposes and receives a Class 2 serial data message from the Powertrain Control Module (PCM) for PRNDL status.
