The fuel level is gauged by the fuel level sensors (7/130, 7/143). The signals from the sensors are transmitted to the rear electronic module (REM) (4/58). The rear electronic module (REM) calculates the quantity of fuel remaining by comparing the signals with a tank table stored in the rear electronic module (REM). 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.
