Operation

•  A resistance according to fuel level is sent from the gauge sender unit to the microcomputer.
•  A Fuel injection amount is sent from the PCM via the CAN system to the microcomputer.
•  The microcomputer calculates the average resistance and Fuel injection amount within a specified time, and sends the output signal to the fuel gauge based on the calculated value.
