Electrical Components InspectionNJEL0051FUEL WARNING LAMP OPERATION CHECKNJEL0051S011. Turn ignition switch “OFF”.
2. Disconnect fuel level sensor unit harness connector B29.
3. Connect a resistor (80Ω) between fuel level sensor unit har-
ness connector terminals 4 and 1.
4. Turn ignition switch “ON”.
The fuel warning lamp should come on.
NOTE:
For QG Engine Only
ECM might store the DTC P0180 during this inspection. If the DTC
is stored in ECM memory, erase the DTC after reconnecting the
fuel level sensor unit and fuel pump harness connector. Refer to
EC-48 (With EURO-OBD), 430 (Without EURO-OBD), “HOW TO
ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION”,
“Emission-related Diagnostic Information”, “ON BOARD DIAG-
NOSTIC SYSTEM DESCRIPTION”.

DIODE CHECKNJEL0051S03Check continuity using an ohmmeter.
Diode is functioning properly if test results are as shown in the
figure at left.
Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer to
EL-130, “WARNING LAMP” wiring diagrams.
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction
manual for the tester to be used.

2. Indication can be changed by in the following order by push-
ing multifunction switch.

Average fuel economy
Average vehicle speed
Board computer Display
Range (km or MILES) Displays range to empty with a range of 000.0 to 999.9.
Journey distance (km or MILES) Displays journey distance with a range of 000.0 to 9999
Journey time Displays journey time with a range of 0000:00:00 to 9999:59:59.
Average fuel consumption (/100 km or
MPG)Displays fuel consumption with a range of 00.0 to 999.
Average vehicle speed (km/h or MPH) Displays average vehicle speed with a range of 000 to 999.
RangeNJEL0555S0401The elapsed time indication provides driver with an estimation
of the distance that can be driven before refuelling.The range
is conducted by fuel tank level sensor unit (fuel remaining),
ECM pulse signal (fuel consumption) and vehicle speed signal.
Indication will be renewed every 30 seconds.
When fuel remaining is less than approx. 7.8(6-7/8 Imp qt),
indication will blink as a warning. If the fuel remaining less than
approx. 6.8(6 Imp qt), “– –.–” will be indicated. In this case,
the mode will change to the RANGE mode automatically even
though the display is showing a different item. (See NOTE.)
The range mode includes a low range warning feature: when
the fuel level is low, the range mode is automatically selected
and the digits blink in order to draw the driver′s attention. Press
the “INFO” switch if you wish to return to the mode that was
selected before the warning occurred. The range mark will
remain blinking until next refuelling. When the fuel level drops
even lower, the range display will change to “– – – –”.
Journey DistanceNJEL0555S0402Journey distance indication is conducted by vehicle speed sig-
nal.
If journey distance is reset, journey time will be reset at the
same time.
When pushing “INFO” switch more than approximately 1
second, driving distance will be reset.
Journey TimeNJEL0555S0403Journey time indication is conducted by integration of ignition
ON time.
If journey time is reset, journey distance will be reset at the
same time.
Average Fuel ConsumptionNJEL0555S0404Average fuel consumption indication is conducted by ECM
pulse signal and vehicle speed signal after system is reset.
Indication will be renewed every 30 seconds.

When pushing “INFO” switch more than approximately 1
second, average fuel economy will be reset.
If average fuel consumption is reset, average vehicle speed
will be reset at the same time.
After reset operation, the display shows “– –. –” until the
vehicle is driven 500 m (1,600 ft) or 30 seconds has passed.
Average Vehicle SpeedNJEL0555S0405Average vehicle speed indication is conducted by running dis-
tance and running time.
Indication will be renewed every 30 seconds.
When pushing “INFO” switch more than approximately 1
second, average speed will be reset.
If average vehicle speed is reset, average fuel consumption
will be reset at the same time.
After reset operation, the displays shows “– –.–” for 30 sec-
onds.
HOW TO CHANGE/RESET INDICATIONNJEL0555S05Indication can be changed by in following order by pushing “INFO”
switch less than approximately 1 second.

AGE FUEL CONSUMPTION,AVERAGE VEHICLE SPEED
Continuous pushing the “INFO” switch (more than 3 second)
can reset the indication of journey distance (trip), journey time
(hour meter), average fuel consumption and average vehicle
speed.
NOTE:
After the display changes automatically, the indication can be
changed to the last mode by pushing the switch. In this case, the
cursor will blink as a warning.
