NORMAL OPERATING CONDITION
COMPASS
COMPASS : DescriptionINFOID:0000000009461756
COMPASS
• The electronic compass is highly protected from changes in most magnetic fields. However, some large
changes in magnetic fields can affect it. Some exampl es 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 cont inuously 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 inco rrect direction or the reading is erratic or locked, ver-
ify the correct zone variance.
Symptom Chart
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, car washes, etc.)
• Compass was calibrated incorrectly or
in the presence of a strong magnetic
field. Perform Calibration. Refer to
MWI-16,
"COMPASS : Description".
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 Variatio
n Setting if correct
reading is desired in that location. Refer to
MWI-16, "COMPASS : Description"
