  1. Put a check mark to "No indication" if some of unit names listed on the column of diagnosis system selection screen of a check sheet table are not displayed on "SELECT SYSTEM" screen attached to the check sheet.
    NOTE: Do not put a check mark on items in the column of "No indication" on the check sheet when displaying all items on "SELECT SYSTEM" screen.
  2. Confirm the unit name that "UNKWN" is displayed from the copy of "CAN DIAG SUPPORT MNTR" screen of "ENGINE" attached to the check sheet, and then put a check mark to the check sheet table.
    NOTE: In "CAN DIAG SUPPORT MNTR" screen, "UNKWN" is displayed on "VDC/TCS/ABS", "METER/M & A", "BCM/SEC", "IPDM E/R" and "AWD/4WD". Put a check mark to it.
  3. Confirm the unit name that "UNKWN" is displayed on the copy of "CAN DIAG SUPPORT MNTR" screen of "A/T" as well as "ENGINE". And then, put a check mark to the check sheet table.
    NOTE:
    • For "A/T", "UNKWN" is displayed on "VDC/TCS/ABS", "METER/M & A", "ICC/e4WD" and "AWD/4WD". But put a check mark to "VDC/TCS/ABS", "METER/M & A" and "AWD/4WD" because "UNKWN" is listed on the column of reception diagnosis of the check sheet table.

  4. For display control unit, put a check mark in the following procedure.
    1. Copy to "CAN DIAG SUPPORT MONITOR Check Sheet" (B) from the display screen (A). Refer to "CAN COMMUNICATION LINE CHECK "
    2. Read "CAN DIAG SUPPORT MONITOR Check Sheet" (B) with "Display control unit Translation Sheet" (C).
    3. Check "UNKWN" with a check mark. Put a check mark to the check sheet table.
    NOTE: In "CAN DIAG SUPPORT MONITOR Check Sheet" (B), check marks are put to "CAN CIRC 3", "CAN CIRC 6", "CAN CIRC 8" and "CAN CIRC 9". But, in the column of the check sheet table indication in "Display control unit Translation Sheet" (C), "ECM" is listed only for "CAN CIRC 3". Therefore, put a check mark to "ECM" because "UNKWN" is listed on the column of reception diagnosis of the check sheet table.
