The fuel level is gauged by the fuel level sensor (7/130). The signal from the sensor is transmitted to the central electronic module (CEM) (4/56). The central electronic module (CEM) calculates the remaining quantity of fuel by comparing the signals with a tank table. Information about the quantity of fuel is transmitted via the Control area network (CAN) to the driver information module (DIM) (5/1) where the fuel level is displayed on the fuel gauge.
