Instrument cluster
The VDO or Moto Meter instrument cluster is made on printed circuits on a flexible board.
The lower part of the instrument cluster contains warning lights for oil pressure, high beam headlights, turn signals, brake fluid level and parking brake, battery charging, and fuel injection system malfunction (depending on the model).
Note: The ABS brake system indicator light is located on the instrument panel to the left of the light switch, and the coolant temperature indicator light is built into the coolant temperature gauge.
The instrument cluster includes a coolant temperature gauge, a fuel gauge with a 10-liter fuel remaining sector, a digital clock, an electronic speedometer with a totalizer and daily trip meter, and a tachometer. For instrument cluster details and the purpose of the instrument cluster connector pins, see Fig. 8-18 and 8-16.

Note
1. On some vehicles, the supply voltage of the devices is regulated by a voltage stabilizer within the range of 9.75-10.25.
2. When the ignition or instruments are turned on, the coolant temperature indicator lamp flashes several times, indicating that it is working properly.
