System DescriptionEKS00FV3
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.

2. Print all the data of “CAN DIAG SUPPORT MNTR” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” dis-
played on CONSULT-II.
3. Attach the printed sheet of “SELF-DIAG RESULTS” and “CAN DIAG SUPPORT MNTR” onto the check
sheet. Refer to LAN-54, "
CHECK SHEET" .
4. Based on the “CAN DIAG SUPPORT MNTR” results, put marks “v” onto the items with “NG” or “UNKWN”
in the check sheet table. Refer to LAN-54, "
CHECK SHEET" .
NOTE:
If a check mark is put on “NG” on “INITIAL DIAG (Initial diagnosis)”, replace the control unit.
The “CAN DIAG SUPPORT MNTR” items, which are not in check sheet table, are not related to diag-
nostic procedure on service manual.
So it is not necessary to check the status of the “CAN DIAG SUPPORT MNTR” items not in check
sheet table.
5. According to the check sheet results (example), start inspection. Refer to LAN-55, "
