CAN COMMUNICATION

Revision: 2006 July

2007 Murano

CAN COMMUNICATION

PFP:23710

System Description

NKS002CT

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CAN Communication Unit

NKS002CU

Refer to

DI-82, "CAN Communication Unit"

in “LAN SYSTEM”.

Precautions for Compass

NKS004J6

NOTE:

●

Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the
operation of the compass.

●

When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not
spray glass cleaner directly on the mirror as it may cause the liquid cleaner to enter the mirror housing.

System Description

NKS004J7

●

This electronic compass is able to display 8 primary directions: N, NE, E, SE, S, SW, W, NW.

●

The compass switch (1) is used to operate the compass.

Switch Operation

●

All standard compasses determine direction relative to Magnetic North; however, this electronic compass
is designed to display direction relative to True North.

●

The difference between Magnetic North and True North varies from place to place across the surface of
the earth.

●

This electronic compass must be “told” approximately where it is on the earth’s surface so that the Mag-
netic North reading can be properly converted into a True North display.

●

To tell the electronic compass where it’s at, the earth is separated into numbered “Zone Variances”. The
Zone Variance number in which the compass is to function must be entered into this electronic compass.

●

Each zone is magnetically about 4.2

wide. Typically, anything under 22.5

total zone change is not

noticed on the electronic compass display. However, over 22.5

, a reading may be off by one or more pri-

mary directions.

●

On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do
not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vaca-
tion. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the
vehicle is “permanently” moved to a new location, it is recommended that the compass zone be reset.

Troubleshooting

NKS004J8

●

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-85, "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-85, "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

NKS004J9

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

Press and hold the compass switch for 3 – 9 seconds.

The current zone setting appears on the compass display.

Find the current geographical location number in the Zone Varia-
tion Chart.

Select the new zone number. (Press the compass switch until
the new zone number appears on the compass display.)

After select the new zone number, the compass display will
automatically shows a direction within a few seconds.

Preform the following Calibration Procedure for more accurate
indications.

Calibration Procedure

NKS004JA

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.

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

DI-85, "Zone Variation Set-

ting Procedure"

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

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

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.

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.
