TroubleshootingNKS003HS
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-108, "
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-108, "
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 ProcedureNKS003HT
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 ProcedureNKS003HU
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-108, "
Zone Variation
Setting Procedure" .
2. Press and hold the inside mirror 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.

REAR VIEW MONITORPFP:28260
System DescriptionNKS0031T
The rear view monitor is equipped to check the rearward of the vehicle with display when A/T selector
lever is in reverse position.
The lines of vehicle sides and the distance from the rear end of the vehicle are provided on display as a
guide. It allows the driver to know the distance between the vehicle and a rearward object, and the width
of the vehicle much easier.
POWER SUPPLY AND GROUND
Power is supplied at all time
through 10A fuse [No. 19, located in fuse block (J/B)]
to rear view camera control unit terminal 1.
When ignition switch is in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to rear view camera control unit terminal 2.
When ignition switch is in ON or START position, power is supplied
through 10A fuse (No. 83, located in IPDM E/R)
to back-up lamp relay terminals 1 and 3.
Ground is supplied
to rear view camera control unit terminal 3
through grounds M35, M45 and M85.
AV COMMUNICATION LINE
Rear view camera control unit is connected to the following units with AV communication line. Each unit trans-
mits/receives data with AV communication line.
NAVI control unit
Display
Display control unit
A/C and AV switch
REAR VIEW CAMERA OPERATION
When A/T selector lever is reverse position, power is supplied
through back-up lamp relay terminal 2
to TCM terminal 7.
Then back-up lamp relay is energized,
from back-up lamp relay terminal 5
to rear view camera control unit terminal 4.
Then, rear view camera control unit is sent camera ON signal
through rear view camera control unit terminal 8
to rear view camera terminal 1.
An image taken by rear view camera is sent
through rear view camera terminals 3 and 4
to rear view camera control unit terminals 10 and 9.
Then an image is sent
through rear view camera control unit terminals 12 and 14
to the display terminals 15 and 16.
An image of rear view will be projected on the display.
