CAN COMMUNICATION
System DescriptionINFOID:0000000001328518
CAN (Controller Area Network) is a serial communication li ne 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 UnitINFOID:0000000001328519
Refer to LAN-43, "CAN System Specification Chart" in “LAN SYSTEM”.

COMPASS
COMPASS
Precaution for CompassINFOID:0000000001328520
NOTE:
 Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the oper-
ation 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 c ause the liquid cleaner to enter the mirror housing.
System DescriptionINFOID:0000000001328521
 This electronic compass is able to display 8 primary directions: N, NE, E, SE, S, SW, W, NW.
 The inside mirror switch (2) is used to operate the compass and
automatic anti-glare system.
Switch Operation
NOTE:
For further details of the compass and automatic anti-glare system, refer to Owner's Manual
 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 w here it is on the earth’s surface so that the Magnetic
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 primary direc-
tions.
 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 vacation. The
typical driver will not notice any difference on the display within 3 or 4 zones. However, if the vehicle is “per-
manently” moved to a new location, it is recommended that the compass zone be reset.
TroubleshootingINFOID:0000000001328522
 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.
