1. When there are no indications of “BCM”, “METER A/C AMP”, “AUTO DRIVE POS.” or “IPDM E/R” on
“SELECT SYSTEM” display of CONSULT-II, print the “SELECT SYSTEM”.
2. Print all the data of “SELF-DIAG RESULTS” for “ENGINE”, “A/T”, “ALL MODE AWD/4WD”, “BCM”,
“METER A/C AMP”, “ABS”, “AUTO DRIVE POS.”, and “IPDM E/R” displayed on CONSULT-II.
3. Print all the data of “CAN DIAG SUPPORT MNTR” for “ENGINE”, “A/T”, “ALL MODE AWD/4WD”, “BCM”,
“METER A/C AMP”, “ABS”, “AUTO DRIVE POS.”, and “IPDM E/R” displayed on CONSULT-II.
4. Attach the printed sheet of “SELECT SYSTEM”, “SELF-DIAG RESULTS” and “CAN DIAG SUPPORT
MNTR” onto the check sheet. Refer to LAN-174, "
CHECK SHEET" .
5. Based on the indications of “SELECT SYSTEM” and the results of “CAN DIAG SUPPORT MNTR”, put
marks “v” onto the items with “No indication”, “NG”, or “UNKWN” in the check sheet table. Refer to LAN-
174, "CHECK SHEET" .
NOTE:

If “NG” is displayed on “INITIAL DIAG (Initial diagnosis)” as “CAN DIAG SUPPORT MNTR” for the diag-
nosed control unit, 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 “CAN DIAG SUPPORT MNTR” items which are not indi-
cated in check sheet table.
6. Check CAN communication line of the integrated display system. Refer to AV- 8 5 , "
CAN Communication
Line Inspection" .
7. Attach the CAN DIAG MONITOR check sheet onto the check sheet. Refer to LAN-174, "
CHECK SHEET"
.

8. Mark the “NG” or “UNKWN” item of the check sheet table with “v” from the result of CAN DIAG MONITOR
check sheet. Refer to LAN-174, "
CHECK SHEET" .
NOTE:
If “NG” is displayed on “CAN COMM” as “CAN DIAG MNTR” for the diagnosed control unit, replace the
control unit. Refer to AV- 8 5 , "
CAN Communication Line Inspection" .
9. According to the check sheet results (example), start inspection. Refer to LAN-176, "
