CALIBRATION (COMPASS)

Work Procedure

INFOID:0000000009651493

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 completed.

• 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

MWI-65, "Work Proce-

dure"

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.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000009651494

CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detectability. Many
electronic control units are equipped onto vehicles, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with two 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.
