3. Print all the data of "CAN DIAG SUPPORT MNTR" for "ENGINE", "METER A/C AMP", "BCM", "ABS" and "IPDM E/R" displayed on CONSULT-II.
4. Based on the indications of "SELECT SYSTEM" and the results of "CAN DIAG SUPPORT MNTR", put marks onto the items with "No indication", "NG", or "UNKWN" in the check sheet table. NOTE: If "NG" is displayed on "INITIAL DIAG (Initial diagnosis)" as "CAN DIAG SUPPORT MNTR" for the diagnosed control unit, replace the control unit. The "CAN DIAG SUPPORT MNTR" items which are not in check sheet table are not related to diagnostic procedure on service manual. Therefore, it is not necessary to check the status of the "CAN DIAG SUPPORT MNTR" items not in check sheet table.
