Work Flow
1. When there are no indications of "TRANSMISSION", "METER A/C AMP" or "AUTO DRIVE POS." on "SELECT SYSTEM" display of
CONSULT-II, print the "SELECT SYSTEM".
2. Print all the data of "SELF-DIAG RESULTS" for "ENGINE", "TRANSMISSION", "BCM", "METER A/C AMP", "AUTO DRIVE POS." and
"ABS" displayed on CONSULT-II.
3. Print all the data of "DATA MONITOR (CAN DIAG SUPPORT MNTR)" for "ENGINE", "TRANSMISSION", "BCM", "METER A/C AMP",
"AUTO DRIVE POS." and "ABS" displayed on CONSULT-II.
4. Attach the printed sheet of "SELECT SYSTEM", "SELF-DIAG RESULTS" and "DATA MONITOR (CAN DIAG SUPPORT MNTR)" onto the
check sheet. Refer to "CHECK SHEET".
5. Based on the indications of "SELECT SYSTEM" and the results of "DATA MONITOR (CAN DIAG SUPPORT MNTR)", put marks "v" onto
the items with "No indication", "NG", or "UNKWN" in the check sheet table. Refer to "CHECK SHEET".
NOTE:
-
If "NG" is displayed on "CAN COMM" as "DATA MONITOR (CAN DIAG SUPPORT MNTR)" for the diagnosed control unit, replace the
control unit.
-
The "DATA MONITOR (CAN DIAG SUPPORT MNTR)" items, which are not in check sheet table, are not related to diagnostic procedure.
So it is not necessary to check the status of "DATA MONITOR (CAN DIAG SUPPORT MNTR)" items which are not indicated in check
sheet table.
6. Check CAN communication line of the navigation system. Refer to "CAN Communication Line Check". See: Accessories and Optional
Equipment/Navigation System/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Non-Trouble Code Procedures/CAN
Communication Line Check
7. Attach the CAN DIAG SUPPORT MONITOR check sheet onto the check sheet. Refer to "CHECK SHEET".
