MWI-91

< SYMPTOM DIAGNOSIS >

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"

YES

>> GO TO 2.

>> Repair harness or connector.

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"

>> Replace ambient sensor. Refer to

HAC-145, "Removal and Installation"

MWI-92

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

MWI-21,

"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

MWI-66,

"Work Procedure"

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

MWI-65, "Work Procedure"
