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.

cate malfunction in Diagno-
sis mode.
One of speedometer/
tachometer/fuel gauge/

cates malfunction in Diag-
nosis mode.1. Meter/Gauge
2. Unified meter control unit1. Check resistance of meter/gauge indicating malfunc-
tion. If the resistance is NG, replace the meter/gauge.
Refer to ªMETER/GAUGE RESISTANCE CHECKº,
EL-162.
2. If the resistance of meter/gauge is OK, replace unified
meter control unit.
