Fuel Receiver Gauge Malfunction [11/2023 - ]: Description

1. The combination meter assembly receives the fuel level signal via direct line from the fuel sender gauge assembly and the fuel consumption signal from the ECM via CAN communication, then calculates the fuel level in the fuel tank and displays the calculated value on the fuel receiver gauge.

1. During normal driving:
   1. During driving, the value of the fuel receiver gauge is updated based on the reduction in the fuel level. The reduction is calculated by deducting the value calculated based on the fuel consumption signal sent by the ECM from the value calculated based on the signal sent by the fuel sender gauge assembly.
2. During refueling:
   1. As the fuel level in the fuel tank increases during refilling, the output value of the fuel sender gauge assembly changes. When the combination meter assembly detects a change in the output value of the fuel sender gauge assembly of a certain value or more, it determines that fuel is being added and calculates the added amount. This control is called refueling judgment and the fuel receiver gauge display is updated in accordance with the fuel level calculated based on the refueling judgment.
