Example of Filling in Check Sheet When Initial Conditions Are Reproduced
1.
Put a check mark to “No indication” if some of unit names listed on the column of diagnosis system selec-
tion 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”,
“ICC”, “BCM/SEC”, “IPDM E/R” and “AWD/4WD/e4WD”. But put a check mark to “VDC/TCS/ABS”,
“METER/M&A”, “BCM/SEC”, “IPDM E/R” and “AWD/4WD/e4WD” because “UNKWN” is listed on the col-
umn of reception diagnosis of the check sheet table.
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.

Display control unit reads the CAN diagnosis support monitor check sheet (B)
transferred from the display screen (A). The transferred CAN diagnosis support mon-
itor check sheet is copied to the Check sheet, and conversed according to the Display control unit
Translation Sheet. And then put a check mark to the check sheet table.
NOTE:
In the CAN diagnosis 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.
