System DescriptionNJEL0442UNIFIED CONTROL METERNJEL0442S01+Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled totally
by control unit built-in combination meter.
+Digital meter is adopted for odo/trip meter.*
*The record of the odo meter 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 segment can be checked in diagnosis mode.
+Meter/gauge can be checked in diagnosis mode.

Combination Meter Self-DiagnosisNJEL0447PERFORMING SELF-DIAGNOSIS MODENJEL0447S011. Turn the ignition switch to the ªLOCKº position.
2. Press both reset buttons on the combination meter and keep
them depressed.
3. Turn the ignition switch to the ªONº position, while keeping the
reset buttons pressed.
4. Release both reset buttons then self-diagnosis will start. The
sequence (A to L) is activated by press the either reset buttons.
NOTE:
If either reset button is not pressed for 20 seconds at each step or
if the ignition switch is turned OFF, the self-diagnosis mode is
exited.

Combination Meter Calibration
After replacing a combination meter, it might be necessary to cali-
brate the fuel gauge/low fuel warning lamp. In case the fuel warn-
ing lamp is flashing after replacing the combination meter perform
the following:
1. Press both reset buttons.
2. Turn the ignition ONand keep the reset buttons depressed
for at least 5 seconds.
3. Release both reset buttons.
The low fuel warning lamp will stop flashing and the combina-
tion meter will show CALL and possibly CALL FAIL. Showing
CALL FAIL does not indicate a concern as this might be related
to the current (unexpected) amount of fuel in the tank.
