Engine Coolant Temperature Signal InspectionINFOID:0000000001328447
Symptom: Water temperature gauge indication is malfunction.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Connect CONSULT-III, and start engine.
2. Select “METER/M&A” on CONSULT-III.
3. Using “W TEMP METER” on “Data Monitor”, compare the value of “Data Monitor” with water temperature
gauge pointer of combination meter.
OK or NG
OK >> GO TO 2.
NG >> Replace combination meter.
2.CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
Select “Data Monitor” of CONSULT-“COOLAN TEMP/S ” of “ENGINE” and “W TEMP METER” of “METER/
M&A”.
OK or NG
OK >> Perform self-diagnosis of ECM. Refer to EC-117, "CONSULT-III Function (ENGINE)" (VQ35DE)
or EC-695, "
CONSULT-III Function (ENGINE)" (VK45DE).
NG >> Replace unified meter and A/C amp. Refer to DI-32, "
Removal and Installation of Unified Meter
and A/C Amp".
Fuel Level Sensor Signal InspectionINFOID:0000000001328448
Symptom:
 Fuel gauge indication is malfunctioning.
 Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms are not malfunctions.
Fuel gauge Depending on vehicle posture 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 posture or driving circumstance, t he fuel in the tank flows and the warning lamp ON
timing may change.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Select “METER A/C AMP” on CONSULT-III.
2. Using “FUEL METER” on “Data Monitor”, compare t he value of “Data Monitor” with fuel gauge pointer of
combination meter.
OK or NG
Water temperature gauge pointer Reference value of data monitor [ °C ( °F)]

Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesINFOID:0000000001328449
1.CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates onl y during driving or at the instant of stopping.
Does the indication value vary only during driving or at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Move to FULL PositionINFOID:0000000001328450
1.QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES >> GO TO 2.
NO >> GO TO 3.
2.QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Be sure to fuel the vehicle with the ignition swit ch OFF. Otherwise, it will take a long time to move
to FULL position because of the c haracteristic of the fuel gauge.
NO >> GO TO 3.
3.QUESTION 3
Is the vehicle parked on an incline?
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4.QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES >> Check the fuel level sensor unit. Refer to DI-21, "Electrical Component Inspection".
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
Odo/Trip Meter and Illuminati on Control Switch InspectionINFOID:0000000001328451

Removal and Installation of Odo/
Trip Meter and Illumination Control Switch".
2. Check continuity odo/trip meter and illumination control switch. Refer to DI-21, "
Electrical Component
Inspection".
OK or NG
OK >> Replace combination meter.
NG >> Replace odo/trip meter and illumination control switch.
