Tachometer Repair

The tachometer display can be compared to the exact digital engine speed that is available on an engine data scanner. The digital engine speed can also be displayed on the HVAC panel. Press the fan up and down buttons together for a few seconds until the display shows -00. Then press the fan up button until the display shows -06. Lastly, press the fan button that is located between the fan up and down buttons once. The display will show the engine speed. The number multiplied by 25 = engine speed.
