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:0000000005395022
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:0000000005395023
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:0000000005395024
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.

• When the combination meter receives light warning signal, it sounds warning chime.
PARKING BRAKE WARNING CHIME
The parking brake warning chime sounds when the parking brake is applied and vehicle speed reaches
approximately 2 km/h (1 MPH).
• The combination meter receives a parking brake applied signal from the parking brake switch.
• When the combination meter receives a vehicle speed si gnal from the ABS actuator and electric unit (control
unit) (with ABS), vehicle speed sensor (without ABS or CVT) or the TCM (with CVT, without ABS), it sounds
the buzzer.
