Fuel Gauge
The ECM averages the fuel tank level reading from the
fuel level sensor over time and will also average the value if a circuit fault were to occur. The ECM sends this averaged information to the BCM over the CAN link. The BCM averages the information for fuel tank sloshing (vehicle speed) and sends this averaged fuel level to the I/P cluster over the Class II link. The I/P cluster then positions the gauge.
