NORMAL OPERATING CONDITION
COMPASS
COMPASS : Description
INFOID:0000000001606729
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 the incorrect direction or the reading is erratic or locked, ver-
ify the correct zone variance.

INFORMATION DISPLAY
INFORMATION DISPLAY : Description
INFOID:0000000001606730
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 unified meter and A/C amp.
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 (4 US gal, 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 performed in such a
case.
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
.
