Fuel Gauge Position

Range: 0 - 250 Counts
This data indicates what message is being sent from the BCM to the instrument cluster in order to control the fuel gage pointer position. The BCM reads the fuel level sensor value in ohms. The sensor performs the following functions:
1. Filters the system in order 10 prevent fuel gage slosh.
2. Sends the fuel level information on the SPI data line in counts to the instrument cluster.
3. The cluster then drives the fuel gauge pointer.




The fuel gauge SPI counts value to the fuel gauge (pointer) position ratio are included in the following table:

The BCM also transmits class 2 serial data fuel messages to the PCM for OBDII purposes. The controller receives a class 2 serial data message from the PCM for PRNDL status.
