< SYMPTOM DIAGNOSIS >
THE FUEL GAUGE POINTER DOES NOT MOVE
SYMPTOM DIAGNOSIS
THE FUEL GAUGE POINTER DOES NOT MOVE
DescriptionINFOID:0000000003792601
Fuel gauge needle will not move from a certain position.
Diagnosis ProcedureINFOID:0000000003792602
1.CHECK FOR THE COMBINATION METER IN SELF-DIAGNOSIS MODE
Check that the fuel gauge needle moves normally by using self-diagnosis function of the combination meter.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace combination meter. Refer to MWI-126, "
Removal and Installation".
2.CHECK COMBINATION METER OUTPUT SIGNAL
1. Connect CONSULT-III.
2. Select the “Data Monitor” for the “METER/M&A” and compare the “FUEL METER” monitor value with the
fuel gauge reading on the combination meter. Refer to MWI-45, "
Component Function Check".
Does monitor value match fuel gauge reading?
YES >> GO TO 3.
NO >> Replace combination meter.
3.CHECK FUEL LEVEL SENSOR SIGNAL CIRCUIT
Check the fuel level sensor signal circuit. Refer to MWI-45, "
DiagnosisProcedure".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair harness or connector.
4.CHECK FUEL LEVEL SENSOR UNIT
Perform a unit check for the fuel level sensor unit. Refer to MWI-46, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace fuel level sensor unit. Refer to FL-5, "
Removal and Installation".
5.CHECK FLOAT INTERFERENCE
Check that the float arm interferes with or binds to other components in the fuel tank.
Is the inspection result normal?
YES >> Replace combination meter.
NO >> Repair or replace malfunctioning parts.

THE AMBIENT TEMPERATURE DISPLAY IS INCORRECT
DescriptionINFOID:0000000003792615
 The displayed ambient air temperature is higher than the actual temperature.
 The displayed ambient air temperature is lower than the actual temperature.
Diagnosis ProcedureINFOID:0000000003792616
NOTE:
Check that the symptom is not applicable to the normal operating condition before starting diagnosis. Refer to
MWI-124, "
INFORMATION DISPLAY : Description".
1.CHECK AMBIENT SENSOR SIGNAL CIRCUIT
Check the ambient sensor signal circuit.
 Refer to HAC-45, "
Diagnosis Procedure" (without 7 inch display).
 Refer to HAC-167, "
Diagnosis Procedure" (with 7 inch display).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK AMBIENT SENSOR UNIT
Perform a unit check for the ambient sensor.
 Refer to HAC-46, "
Component Inspection" (without 7 inch display).
 Refer to HAC-168, "
Component Inspection" (with 7 inch display).
Is the inspection result normal?
YES >> Replace combination meter.
NO >> Replace ambient sensor. Refer to VTL-24, "
Removal and Installation" (without 7 inch display) or
VTL-81, "
Removal and Installation" (with 7 inch display).

NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
INFORMATION DISPLAY
INFORMATION DISPLAY : DescriptionINFOID:0000000003792618
AMBIENT AIR TEMPERATURE
The displayed ambient air temperature on the information display may differ from the actual temperature
because it is a corrected value calculated from the ambient sensor signal by the combination meter. Refer to
MWI-27, "
INFORMATION DISPLAY : System Description" for details on the correction process.
POSSIBLE DRIVING DISTANCE
The calculated possible driving distance may differ from the actual distance to empty if the refueling amount is
approximately 15 (3-3/10 Imp gal) or less. This is because the refuel control (moves the fuel gauge needle
quicker than normal judging that the driver is refueling the vehicle) is not performing.

FUNCTION DIAGNOSIS
RELAY CONTROL SYSTEM
System DiagramINFOID:0000000003773255
System DescriptionINFOID:0000000003773256
IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input sig-
nals from various sensors and the request signals received from control units via CAN communication.
CAUTION:
IPDM E/R integrated relays cannot be removed.
