The operation of the devices is controlled by an electronic module, which receives signals from sensors. Temperature and fuel level indicators are electromagnetic. The tachometer and speedometer needles are driven by stepper motors.
The electronic instrument cluster cannot be repaired, except for replacing the control lamps and instrument lighting lamps. The component units of the instrument cluster are not supplied as spare parts. Therefore, if one of the devices fails, the cluster must be replaced as a whole.
Helpful advice. To avoid damaging the instrument cluster glass, do not clean it with any solvents. You can wash the glass with a mild soap solution. It is best to use a glass cleaner, such as "Sekunda".
