Fuel Gauge
There are either one or two sensors in the fuel tank, depending on the design of the tank, from which the central electronic module (CEM) measures the voltage level and sends the signal readings on to the driver information module (DIM). The driver information module (DIM) receives the signals, interprets them and displays the current fuel level in the fuel gauge.
The low fuel level warning lamp lights when the fuel level is low. The warning lamp informs the driver that the fuel level is low.
The warning lamp lights when there are less than 9 liters of gasoline or 7.5 liters diesel, depending on the engine type, in the tank.
The fuel gauge is not sensitive to rapid change. This is to prevent incorrect values being displayed when cornering or driving on slopes for example.
In the event of a fault, and when the driver information module (DIM) cannot interpret the readings from the central electronic module (CEM), a red LED will illuminate on the tank gauge. In the event of a fault in the driver information module (DIM) software, the red LED will blink at start-up for 1 minute and then the fuel gauge will be switched off.
