Operation
Voltmeter and fuel consumption instrument 210 (EDU1) forms part of an electronic digital display which provides information on the fuel
consumption of the car and the voltage of the electrical system. The display is located below the speedometer.
Instrument 210, control unit 200 for the fuel injection system and sensor 132 will be energized across fuse 13 when the ignition switch is set to the
drive position. The instrument and clock 49 are also continuously supplied from fuse 17 (independent of the ignition switch position).
The following values can be successively accessed by depressing the INFO button below the clock:
Instantaneous fuel consumption
Mean fuel consumption in liters/100 km or mph..
Voltage of the electrical system
To be able to calculate the values shown on the display, the instrument must be supplied with information on the speed of the car and its fuel
consumption.
Information on the speed of the car is obtained from sensor 132 in the speedometer, whereas information on the fuel consumption is obtained from the
control unit (terminal 13) of the fuel injection system. The control pulses from the control unit are used for the injection valves.
The brightness of the display under daylight conditions is controlled by a sensor mounted on the DCC unit or clock. In darkness, the brightness can be
controlled by means of instrument lighting rheostat 16.
