5.CHECK FUEL LEVEL SENSOR UNIT
Check fuel level sensor unit. Refer to DI-20, "
Electrical Component Inspection" .
OK or NG
OK >> Check fuel level sensor unit installation, and c heck whether the float arm interferes or binds with
any of the internal components in the fuel tank. Repair or replace malfunctioning part, if neces-
sary.
NG >> Replace fuel level sensor unit.
Fuel Gauge Fluctuates, Indica tes Wrong Value, or VariesINFOID:0000000005929174
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.
Fuel Gauge Does Not Move to Full-positionINFOID:0000000005929175
1.OBSERVE FUEL GAUGE
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.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.
4.OBSERVE FUEL GAUGE POINTER
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES or NO
YES >> Check the components. Refer to DI-20, "Electrical Component Inspection" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
DTC [U1000] CAN Communication CircuitINFOID:0000000005929176
Symptom: Display CAN COMM CIRC [U1000] at the re sult of self-diagnosis for combination meter.
1.CHECK CAN COMMUNICATION
1. Select "SELF-DIAG RESULTS" mode for "METER/M&A" with CONSULT-III.
2. Print out CONSULT-III screen.
>> Go to "CAN SYSTEM". Refer to LAN-17, "
Trouble Diagnosis Flow Chart".

FUEL LEVEL SENSOR UNIT CHECK
For removal, refer to FL-6, "Removal and Installation" .
Check Fuel Level Sensor Unit and Fuel Pump
Check resistance between terminals 2 and 5.
1* and 2*: When float rod is in contact with stopper.
Check Fuel Level Sensor Unit and Fuel Pump Harness
Check continuity at the following terminals.
• If the results of check are NG, replace fuel pump assembly. If the
results of check are OK, replace fuel level sensor unit.
