Self-Diagnosis Mode of Combination MeterNKS0005Z
SELF-DIAGNOSIS FUNCTION

Odo/trip meter segment and A/T indicator segment operation can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
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 “trip A” displayed, the mileage on “trip A” will indicate “0000.0”,
but the actual trip mileage will be retained. (The “trip B” functions in the same way.)
2. Turn ignition switch OFF.
3. While pressing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0000.0”.
5. Press 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 and A/T indicator illuminate, and simultaneously the low-fuel warn-
ing lamp indicator illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:

Check combination meter power supply and ground circuit when self-diagnosis mode of combination
meter does not start. Replace combination meter if normal.

If any of the segments is not displayed, replace combination meter.
7. Press the odo/trip meter switch. Each meter/gauge should indi-
cate as shown in the figure while pressing odo/trip meter switch.
(At this time, the low-fuel warning lamp goes off).
NOTE:
If any of the meter/gauge is not activated, replace combination
meter.
CONSULT-III Function (METER A/C AMP)NKS00060
