Troubleshooting

●

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
influences, 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,
verify the correct zone variance.

Troubleshooting 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, carwashes, etc.)

●

Compass was calibrated incorrectly or in 
the presence of a strong magnetic field.

Perform Calibration.
Refer to 

DI-104, "Calibration Procedure"

 .

Compass shows the wrong direction.

Compass does not change direction – 
appears “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 

DI-104, "Zone Variation Setting 

Procedure"

 .

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.

Zone Variation Setting Procedure

NKS004F5

NOTE:
The zone setting is factory preset (“default” setting) to zone 8.
1.

Press and hold the compass switch for 3 – 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 compass 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 Procedure

NKS004F6

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
if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Cali-
brate the mirror compass if the display shows only one direction or a limited number of directions.

NOTE:

●

If “magnetic hats” are used in the dealership for vehicle identification, remove the hat from the vehicle
before performing the following steps. Do NOT put the hat back on the vehicle after the procedure is com-
pleted.

●

Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power
lines.

●

Turn off “non-essential” electrical accessories (rear window defrost, heater/air conditioning, wipers) and
close the doors.

1.

Verify the correct compass zone setting for the geographical location. Refer to 

DI-104, "Zone Variation

Setting Procedure"

 .

2.

Press and hold the compass switch for more than 9 seconds.

3.

“C” is displayed on the compass display, when calibration starts.

4.

Drive slowly [less than 8 km/h (5 mph)] in a circle until the “C / CAL” is replaced with primary headings (N,
NE, E, SE, S, SW, W, or NW).

NOTE:
This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.

5.

The compass calibration procedure is now complete. The compass should operate normally.

NOTE:
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
repeat the calibration procedure.
