Meter/Gauges Operation and Odo/Trip MeterEKS00EH7
SELF-DIAGNOSIS FUNCTION

Odo/trip meter segment operation can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with the trip meter A displayed, the mileage on the trip meter A will
indicate 0.0 miles, but the actual trip mileage will be retained (The same way for trip B).
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0.0”.
5. Push the odo/trip meter switch at least 3 times (Within 7 seconds after the ignition switch is turned ON).
6. All the segments on the odo/trip meter illuminate, and simultaneously the low-fuel warning lamp indicator
illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:
If any of the segments is not displayed, replace the combination
meter.
