System DescriptionAKS007AO
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Push the switch when the ignition key is in the “ON” or “START” position. The direction will be displayed.
Pushing the “COMP” switch a second time will turn off the display.
1. If the display reads “C” calibrate the compass by driving the vehicle in 3 complete circles at less than 8
km/h (5 MPH).
2. To adjust for compass variance:
a. Press the “COMP” switch for more than 3 seconds. The current zone number will appear in the display.
b. Find your current location and variance zone number on the zone map.
c. Press the “COMP” switch until the new zone number appears in the display. After you stop pressing the
button in, the display will show a compass direction within a few seconds.
NOTE:
1. Do 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.
2. If the compass deviates from the correct indication soon after repeated adjustment, have the compass
checked at an authorized dealer.
3. The compass may not indicate the correct compass point in tunnels 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.)
3. Cleaning the Mirror
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 that may cause the liquid cleaner to enter the mirror housing.

CAN Communication System DescriptionAKS007Z2
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 UnitAKS007YY
Refer to LAN-6, "CAN Communication Unit" in “LAN SYSTEM”.
