DISPLAY
Description
INFOID:0000000009651536
• The door ajar warning is displayed even though all of the doors are closed.
• The door ajar warning is not displayed even though a door is ajar.
Diagnosis Procedure
INFOID:0000000009651537
1.
CHECK BCM INPUT/OUTPUT SIGNAL
Connect CONSULT and check the BCM input signals. Refer to
DLK-241, "Component Function Check"
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
CHECK COMBINATION METER INPUT SIGNAL
Select the “Data Monitor” for the “METER/M&A” and check the “DOOR W/L” monitor value.
Is the inspection result normal?
YES
>> Replace combination meter. Refer to
MWI-93, "Removal and Installation"
NO
>> Replace BCM. Refer to
BCS-98, "Removal and Installation"
3.
CHECK DOOR SWITCH SIGNAL CIRCUIT
Check the door switch signal circuit. Refer to
DLK-241, "Diagnosis Procedure"
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair harness or connector.
4.
CHECK DOOR SWITCH
Perform a unit check for the door switch. Refer to
DLK-242, "Component Inspection"
Is the inspection result normal?
YES
>> Replace combination meter. Refer to
MWI-93, "Removal and Installation"
NO
>> Replace applicable door switch. Refer to
DLK-486, "Removal and Installation"
.

THE AMBIENT TEMPERATURE DISPLAY IS INCORRECT
Description
INFOID:0000000009651538
• The displayed ambient air temperature is higher than the actual temperature.
• The displayed ambient air temperature is lower than the actual temperature.
Diagnosis Procedure
INFOID:0000000009651539
NOTE:
Check that the symptom is not applicable to the normal operating condition before starting diagnosis. Refer to
MWI-92, "INFORMATION DISPLAY : Description"
1.
CHECK AMBIENT SENSOR SIGNAL CIRCUIT
Check the ambient sensor signal circuit. Refer to
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair harness or connector.
2.
CHECK AMBIENT SENSOR
Perform the part check for the ambient sensor. Refer to
HAC-95, "Component Inspection"
.
Is the inspection result normal?
YES
>> Replace combination meter. Refer to
MWI-93, "Removal and Installation"
NO
>> Replace ambient sensor. Refer to
MWI-92
< SYMPTOM DIAGNOSIS >
NORMAL OPERATING CONDITION
NORMAL OPERATING CONDITION
COMPASS
COMPASS : Description
INFOID:0000000009651540
COMPASS
• The electronic compass is highly protected from changes in most magnetic fields. However, some large
changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,
large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While
this does not happen very often, it is possible.
• During normal operation, the compass mirror will continuously update the compass calibration to adjust for
gradual changes in the vehicle's magnetic “remnant” field. If the vehicle is subjected to high magnetic influ-
ences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be
calibrated. If this occurs, perform the calibration procedure.
• If at any time the compass continually displays an incorrect direction or the reading is erratic or locked, verify
the correct zone variance.
Symptom Chart
INFORMATION DISPLAY
INFORMATION DISPLAY : Description
INFOID:0000000009651541
AMBIENT TEMPERATURE
The displayed ambient 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
"INFORMATION DISPLAY : System Description"
for details on the correction process.
DISTANCE TO EMPTY
The calculated distance to empty may differ from the actual distance to empty if the refueling amount is
approximately 15 (4 US gal, 3-1/4 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.
Symptom
Cause
Solution / Reference
The compass display reads “C”.
• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel
bridges, subways, concentrations of
metal, carwashes, etc.)
• Compass was calibrated incorrectly or in
the presence of a strong magnetic field.
Perform Calibration. Refer to
Compass shows the wrong direction.
Compass does not change direction ap-
pears “Locked”.
Compass does not show all the directions,
one or more is missing.
The compass was calibrated but it “loses”
calibration.
On long trips the compass shows the
wrong direction.
Perform zone variation setting if correct
reading is desired in that location. Refer
to
