The most common issue with this unit is a failed power supply that will cause simultaneously speedometer, tachometer, and odometer failure. During this failure the fuel and coolant will continue to operate normally. If you are noticing a fuel or coolant malfunction, it it likely due to a bad sensor and/or wiring in the vehicle. The tachometer can sometimes fail by itself. This service will repair all common items.
