Instrument cluster
The instrument cluster of the brand VDO or Moto Meter is made on printed circuits on a flexible board.
In the lower part of the instrument cluster there are control lamps for oil pressure, switching on the main beam of headlights. direction indicators, brake fluid level and parking brake activation, battery charging, fuel injection system malfunctions (depending on the model).
Note. The ABS brake warning lamp is located on the instrument panel to the left of the light switch. and the coolant temperature warning 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 summing and daily distance counter and a tachometer. Details of a combination of devices and purpose of conclusions of a socket of a combination of devices see on fig. 8-18 and 8-16.

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