Meter/Gauge Operation and Odo/Trip Meter
Segment Check in Diagnosis Mode/Sedan
NJEL0151DIAGNOSIS FUNCTIONNJEL0151S01+Odo/trip meter segment can be checked in diagnosis mode.
+Meters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODENJEL0151S021. Turn ignition switch to ON and change odo/trip meter to ªTRIP
Aº or ªTRIP Bº.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter switch.
4. Confirm that trip meter indicates ª000.0º.
5. Push odo/trip meter switch more than three times within 5
seconds.
SEL110VB
6. All odo/trip meter segments should be turned on.
NOTE:
If some segments are not turned on, unified meter control unit with
odo/trip meter should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
SEL111V
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch
if it is no malfunctioning.
NOTE:
It takes about a few seconds for indication of fuel gauge and water
temperature gauge to become stable.

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.

Combination Meter Self-Diagnosis/HatchbackNJEL0447PERFORMING 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.
