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:
Put a check mark to “No indication” of IPDM E/R because IPDM E/R is not displayed on “SELECT SYS-
TEM” 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”, “ICC”, “IPDM E/R”,
“AWD/4WD/e4WD” and “EPS”. But put a check mark to “VDC/TCS/ABS”, “IPDM E/R” and “AWD/4WD/
e4WD” because “UNKWN” is listed on the column 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 “INTELLIGENT KEY”, “TRANSMISSION”, “AIR PRESSURE MONITOR” and “BCM” as well as
“ENGINE”. And then, put a check mark to the check sheet table.

NOTE:

For “INTELLIGENT KEY”, “UNKWN” is not displayed. Do not put a check to it.

For “TRANSMISSION”, “UNKWN” is displayed on “VDC/TCS/ABS” and “ICC”. But put a check mark to
“VDC/TCS/ABS” because “UNKWN” is listed on the column of reception diagnosis of the check sheet
table.

For “AIR PRESSURE MONITOR”, “UNKWN” is not displayed. Do not put a check to it.

For “BCM”, “UNKWN” is displayed on “IPDM E/R”. Put a check mark to it.

For display control unit, put a check mark in the following procedure.

a.

Copy to “CAN DIAG SUPPORT MONITOR Check Sheet” (B) from the display screen (A). Refer to 

AV-

188, "CAN Communication Line Check"

 .

b.

Read “CAN DIAG SUPPORT MONITOR Check Sheet” (B) with “Display control unit Translation Sheet”
(C).

c.

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 7” and “CAN
CIRC 9”. But, in the column of the check sheet table indication in “Display control unit Translation Sheet”
(C), “IPDM E/R” is listed only for “CAN CIRC 7”. Therefore, put a check mark to “IPDM E/R” because
“UNKWN” is listed on the column of reception diagnosis of the check sheet table.

of “METER A/C AMP”, “AUTO DRIVE POS.”, “ALL MODE AWD/4WD” and “ABS” as well as “ENGINE”.
And then, put a check mark to the check sheet table.

NOTE:

For “METER A/C AMP”, “UNKWN” is displayed on “VDC/TCS/ABS” and “AWD/4WD”. Put a check
mark to it.

For “AUTO DRIVE POS.”, “UNKWN” is not displayed. Do not put a check to it.

For “ALL MODE AWD/4WD”, “UNKWN” is displayed on “TCM”. But, do not put a check mark to their
columns of reception diagnosis of the check sheet table because “UNKWN” is not listed.

For “ABS”, “UNKWN” is displayed on “ECM”, “TCM”, “METER/M&A”, “STRG” and “ICC”. But put a
check mark to “ECM”, “TCM” and “STRG” because “UNKWN” is listed on the column of reception diag-
nosis of the check sheet table.

6.

Perform system diagnosis for possible causes identified.

7.

Perform diagnosis again after inspection and repair. Make sure that repair is completely performed, and
then end the procedure.

Start CAN system trouble diagnosis if this procedure can be confirmed.
