System Description
COMBINATION METER
• Speedometer, odo/trip meter, tachometer, fuel gauge, engine coolant temperature gauge and information display are controlled by the unified meter control unit, which is built into the combination meter.
• Warning and indicator lamps are controlled by the unified meter control unit and by components connected directly to the combination meter.
• Digital meter is adopted for odo/trip meter.* *The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected.
• Odo/trip meter and information display segments can be checked in diagnosis mode.
