CAN COMMUNICATIONPFP:23710
System DescriptionEKS00MHE
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 UnitEKS00MHF
Refer toLAN-30, "CAN Communication Unit"in “LAN SYSTEM”.

COMPASS
COMPASS
PFP:24835
System DescriptionEKS00M4Z
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Press “COMP” switch (1) when ignition switch is in “ON” or “START” position. The direction is displayed.
Pressing “COMP” switch (1) for a second turns off the display (2).
NOTE:
lDo not install the ski rack, antenna, etc. which are attached to
the vehicle by means of a magnet. They affect the operation of
the compass.
lThe compass may not indicate the correct compass point in tun-
nels or while driving up or down a steep hill. (The compass
returns to the correct compass point when the vehicle moves to
an area where the geomagnetism is stabilized.)
lWhen cleaning the mirror, use a paper towel or similar material
dampened with glass cleaner. Do not spray glass cleaner
directly on the mirror as that may cause the liquid cleaner to
enter the mirror housing.
Zone Variation Change ProcedureEKS00MS2
The difference between magnetic north and geographical north is known as variance. In some areas, this dif-
ference can sometimes be great enough to cause false compass reading.
Follow these instructions to set the variance for the particular location if this happens:
1. Press “COMP” switch for more than 3 seconds. The current zone number appears on the display.
2. Find the current location and variance one number on the zone variation chart.
3. Press “COMP” switch until the new zone number appears on the display. After releasing the switch, the
display shows a compass direction within a few seconds.

Correction Functions of the Compass DisplayEKS00MS3
AUTOMATIC CORRECTION
The compass display is equipped with automatic correction function. If the direction is not shown correctly,
perform manual correction procedure set out below.
MANUAL CORRECTION PROCEDURE
When the display reads “C” or “CAL”, calibrate the compass by driving the vehicle in 3 complete circles at less
than8km/h(5MPH).
The compass can be calibrated by driving the vehicle on everyday route. The compass is calibrated once it
has tracked 3 complete circles.
In places where the terrestrial magnetism is extremely disturbed, the initial correction procedure may start
automatically.
