3. CHECK CONTINUITY BETWEEN COMBINATION METER AND UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF.
2. Disconnect combination meter connector and unified meter and
A/C amp. connector.
3. Check continuity between combination meter harness connector
(A) and unified meter and A/C amp. harness connector (B).
OK or NG
OK >> Replace combination meter.
NG >> Repair harness or connector.
Engine Speed Signal Inspection NKS003U8
Symptom: Tachometer indication is malfunction.
1. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Start engine and select “METER A/C AMP” on CONSULT-II.
2. Using “TACHO METER” on “DATA MONITOR”, compare the
value of “DATA MONITOR” to that of tachometer of combination
meter.
Is the value in tachometer almost same as the value in the monitor?
OK >> GO TO 2.
NG >> Replace combination meter. (Perform self-diagnosis of
ECM when the value in the monitor indicates 8191.875
rpm. Then repair or replace the malfunction part.)
2. CHECK ECM OUTPUT SIGNAL
1. Select “ENGINE” on CONSULT-II.
2. Using “ENG SPEED” on “DATA MONITOR”, print out the CON-
SULT-II screen when the engine is idling.
3. Select “METER A/C AMP” on CONSULT-II.
4. Using “TACHO METER” on “DATA MONITOR”, compare the
value of “DATA MONITOR” of the idling speed to that of the
“ENG SPEED”.
OK or NG
OK >> Perform self-diagnosis of ECM. Refer to EC-123, "CON-
SULT-II Function (ENGINE)" (for VQ35DE) or EC-826,
"CONSULT-II Function (ENGINE)" (for VK45DE).
NG >> Replace unified meter and A/C amp.

Engine Coolant Temperature Signal InspectionNKS003U9
Symptom: Water temperature gauge indication is malfunction.
1. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Start engine and select “METER A/C AMP” on CONSULT-II.
2. Using “W TEMP METER” on “DATA MONITOR”, compare the
value of “DATA MONITOR” to the indication of water tempera-
ture gauge of combination meter.
Is the indication of water temperature gauge same as the value in
the monitor?
OK >> GO TO 2.
NG >> Replace combination meter. [Perform self-diagnosis of ECM when the value in the monitor indi-
cates 215°C (419°F). Then repair or replace the malfunction part.]
2. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Select “ENGINE” on CONSULT-II.
2. Using “COOLAN TEMP/S” on “DATA MONITOR”, print out the
CONSULT-II screen.
3. Select “METER A/C AMP” on CONSULT-II.
4. Using “W TEMP METER” on “DATA MONITOR”, compare the
value of “DATA MONITOR” to that of the “COOLAN TEMP/S”.
OK or NG
OK >> Perform self-diagnosis of ECM. Refer to EC-123, "CON-
SULT-II Function (ENGINE)" (for VQ35DE) or EC-826,
"CONSULT-II Function (ENGINE)" (for VK45DE).
NG >> Replace unified meter and A/C amp.
Fuel Level Sensor Signal InspectionNKS003UA
Symptom:

Fuel gauge indication is malfunction.

Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms are not malfunction.
Fuel level sensor unit

Depending on vehicle position or driving circumstance, the fuel level in the tank varies, and the pointer
may fluctuate.

If the vehicle is fueled with the ignition switch ON, the pointer will move slowly.
Low-fuel warning lamp

Depending on vehicle position or driving circumstance, the fuel in the tank flows and the warning lamp ON
timing may change.
Water temperature gauge pointer Reference value of data monitor °C (°F)
Hot Approx. 130 (266)
Middle Approx. 70 - 105 (158 - 221)
Cold Approx. 50 (122)

DATA MONITOR
Operation Procedure
1. Touch “METER A/C AMP” on “SELECT SYSTEM” screen.
2. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
3. Touch either “MAIN SIGNALS” or “SELECTION FROM MENU” on the “DATA MONITOR” screen.
4. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. When “MAIN SIG-
NALS” is selected, main items will be monitored.
5. Touch “START”.
6. Touch “RECORD” while monitoring, then the status of the moni-
tored item can be recorded. To stop recording, touch “STOP”.
