Unified Meter Control Unit: Notes
WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
- Approximately 60 seconds after turning the ignition switch from the ON to the OFF position
- If the battery is disconnected and then reconnected
