1. Print all the data of “SELF-DIAG RESULTS” for “ENGINE”, “ABS” and “ALL MODE AWD/4WD” displayed
on CONSULT-II.
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-72, "
CHECK SHEET" .
4. Based on the results of “CAN DIAG SUPPORT MNTR”, put a check marks onto the items with “NG” or
“UNKWN” in the check sheet table. Refer to LAN-72, "
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-73, "
CHECK SHEET
RESULTS (EXAMPLE)" .
