COMBINATION METER

• Speedometer, odo/trip meter, tachometer, fuel gauge, engine coolant temperature gauge, engine oil pres-

sure gauge, voltage gauge and trip computer 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*, as well as the A/T position indicator display.

*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 A/T indicator segments can be checked in diagnosis mode.

• Meter/gauge can be checked in diagnosis mode.

NOTE:

Under the following conditions, the meters will perform a homing function. The meter pointers will move down

slightly and then move back to the resting position. This is a normal design condition.

• Approximately 60 seconds after turning the ignition switch from the ON to the OFF position

• If the battery is disconnected and then reconnected

Unit

Description

Combination meter

Controls the following with the signals received from each unit via CAN communication and the sig-
nals from switches and sensors.

• Speedometer

• Tachometer

• Engine coolant temperature gauge

• Fuel gauge

• Engine oil pressure gauge

• Odo/trip meter
