  • Speedometer, odometer, tachometer, fuel gauge, oil pressure gauge, voltage gauge, and water temperature gauge are controlled by the unified meter control unit, which is built into the combination meter.
  • Warning indicators are controlled by signals drawn from the CAN communication system, BCM (body control module), and components connected directly to the combination meter.
  • Digital meter is adopted for odometer/trip meters*, as well as the A/T position indicator display. *The record of the odometer is kept even if the battery cable is disconnected.
  • Odometer/trip meters and A/T indicator segments can be checked in diagnosis mode.
  • Meters/gauges 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.
