• Depending on vehicle position or driving circumstance, the fuel in the tank shifts and the indication may fluc-
tuate.
• 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.
LOW-FUEL WARNING LAMP
Depending on vehicle posture or driving circumstances, the fuel level in the tank varies, and the warning lamp
ON timing may be changed.
1.CHECK SELF-DIAGNOSIS
Perform the combination meter self-diagnosis. Refer to DI-12, "
Self-Diagnosis Mode of Combination Meter".
OK or NG
OK >> GO TO 2.
NG >> Replace the combination meter. Refer to IP-10, "
Removal and Installation".
2.CHECK HARNESS CONNECTOR
1. Turn the ignition switch OFF.
2. Check combination meter and fuel level sensor unit and fuel pump terminals (meter-side, and harness-
side) for poor connection.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace terminals or connectors.
3.CHECK HARNESS CONNECTOR OUTPUT SIGNAL
1. Disconnect fuel level sensor unit and fuel pump connector.
2. Turn ignition switch ON.
3. Check voltage between combination meter harness connector M24 terminal 15 and ground.
OK or NG
OK >> GO TO 4.
NG >> Replace the combination meter. Refer to IP-10,
"Removal and Installation".
4.CHECK HARNESS FOR OPEN OR SHORT CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect combination meter connector M24.
3. Check continuity between combination meter harness connector M24 (B) terminal 15 and fuel level sensor unit and fuel pump
harness connector C5 (A) terminal 2.

OK >> GO TO 7.
NG >> Replace the fuel level sensor unit. Refer to FL-5, "
Removal and Installation".
7.CHECK INSTALLATION CONDITION
Check fuel level sensor unit installation, and determine whet her the float arm interferes or binds with any of the
internal components in the fuel tank.
OK or NG
OK >> Replace the combination meter. Refer to IP-10, "Removal and Installation".
NG >> Install the fuel level sensor unit properly.
Fuel Gauge Fluctuat es, Indicates Wrong Value, or VariesINFOID:0000000003533496
1.CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or just before or just after stopping.
Does the indication value vary only during driving or just before or just after stopping?
YES >> The fluctuation may be caused by fuel leve l change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, Refer to DI-18, "
Fuel
Level Sensor Unit Inspection".
Fuel Gauge Does Not Move to Full-positionINFOID:0000000003533497
1.CHECK POINTER MOVEME NT TO FULL-POSITION
Does it take a long time for the pointer to move to full-position?
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK IGNITION SWITCH POSITION
Was the vehicle fueled with the ignition switch ON?
YES or NO
YES >> Be sure to fuel the vehicle with the ignition s witch OFF. Otherwise, it will take a long time for the
pointer to move to full-position because of the characteristic 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 indication with vehicle on a level surface.
NO >> GO TO 4. Continuity should exist.
