Description & Operation: Gauges

On all models except Highlander, standard instrument clusters contain fuel and temperature gauges with telltale warning lights. Some optional instrument panels are equipped with a tachometer, oil pressure gauge and voltmeter. Gauge internal operating components use either a 2-terminal bimetallic strip type or a 3-terminal coil type. The 2-terminal type gauges are generally used on clusters without tachometers.

Highlander is equipped with solid state instrument cluster assembly which can only be serviced by complete assembly replacement. Individual gauge test procedures are not provided by manufacturer.
