The tachometer shows the engine crankshaft speed in revolutions per minute. To do this, it receives control pulses from the ignition system.


These are processed by the electronics and passed on to the pointer measuring mechanism of the instrument.


In case of malfunction, check the corresponding fuse (see Body Electrical System chapter) and the wiring. The instrument cluster circuit board may also cause the fault. The tachometer itself cannot be repaired.
