 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.
Troubleshooting Chart
Zone Variation Setting ProcedureINFOID:0000000001328523
NOTE:
The zone setting is factory preset (“default” setting) to zone 8.
1. Press and hold the inside mirror switch for 6 – 9 seconds.
2. The current zone setting appears on the compass display.
3. Find the current geographical location number in the Zone Varia-
tion Chart.
4. Select the new zone number. (Press the inside mirror switch until the new zone number appears on the compass display.)
5. After select the new zone number, the compass display will automatically shows a direction within a few seconds.
6. Preform the following Calibration Procedure for more accurate indications.
Calibration ProcedureINFOID:0000000001328524
NOTE:
The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause
the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or
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 met-
al, carwashes, etc.)
 Compass was calibrated incorrectly or in
the presence of a strong magnetic field. Perform Calibration.
Refer to
DI-95, "
Calibration 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 Variatio
n Setting if correct
reading is desired in that location.
Refer to DI-95, "
Zone Variation Setting Pro-
cedure".
Compass does not work – No direction is
displayed. Compass not turned ON.
Check for green LED indicator (inside mir-
ror switch).
No power to inside mirror. Check power supply circuit.
