Self-Diagnosis Mode of Combination MeterINFOID:0000000005395014
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom- eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indi cator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”. NOTE:

COMBINATION METERS
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” will indicate “0000.0”,
but the actual trip mileage will be retained. (The same applies for “trip B”.)
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch (1), turn the ignition switch ON.
4. Confirm that the trip meter displays “0000.0”.
5. Push the odo/trip meter switch at least 3 times. (Within 7 sec- onds after the ignition switch is turned ON.)
6. All the segments on the odo/trip meter, and simultaneously the low-fuel warning lamp indicator illumi- nates. At this time, the unified meter control unit is turned to self-diagnosis mode.
• M/T MODELS (1)
• A/T AND CVT MODELS (2)
NOTE:
• Check combination meter power supply and ground circuit when self-diagnosis mode of combination
meter does not start. Replace combination meter if normal. Refer to IP-12, "
Removal and Installation" .
• If any of the segments is not displayed, replace combination meter. Refer to IP-12, "
Removal and Instal-
lation" .
7. Each meter activates while pressing odo/trip meter switch. (At this time, the low-fuel warning lamp turns off, low water temperature indicator lamp and high water temperature warning lamp turn on.)
NOTE:
If any of the meter and gages are not activat ed, replace combination meter. Refer to IP-12, "
Removal and
Installation" .

The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.

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 dr iving or at the 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.

2.IDENTIFY FUELING CONDITION
Was the vehicle fueled with the ignition switch ON?
YES or NO
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.OBSERVE VEHICLE POSITION
Is the vehicle parked on an incline?
YES or NO
YES >> Check the fuel level indicati on with vehicle on a level surface.
NO >> GO TO 4.
