HOW TO USE CHECK SHEET TABLE

Unit names displayed on CONSULT-II.

“No indication”: Put a check mark to it if the unit name described in step 1 is not displayed on “SELECT
SYSTEM” screen of CONSULT-II. (Unit communicating with CONSULT-II via CAN communication line)
“–”: Column not used (Unit communicating with CONSULT-II excluding CAN communication line)

“NG”: Display “NG” when malfunction is detected in the initial diagnosis of the diagnosed unit. Replace the
unit if “NG” is displayed.
“–”: Column not used (Initial diagnosis is not performed.)

“UNKWN”: Display “UNKWN” when the diagnosed unit does not transmit the data normally. Put a check
mark to it if “UNKWN” is displayed on CONSULT-II.

“UNKWN”: Display “UNKWN” when the diagnosed unit does not receive the data normally. Put a check
mark to it if “UNKWN” is displayed on CONSULT-II.
“–”: Column not used (It is not necessary for CAN communication trouble diagnosis.)

NOTE:
CAN communication diagnosis checks if CAN communication works normally. (Contents of data are not diag-
nosed.)

Example of Filling in Check Sheet When Initial Conditions Are Reproduced

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.

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”, “IPDM E/R” and
“AWD/4WD”. Put a check mark to it.

Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen
of “INTELLIGENT KEY”, “TRANSMISSION” 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 “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.

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

AV-

178, "CAN Communication Check"

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

There is a case that some of “CAN DIAG SUPPORT MNTR” and “SELF-DIAG RESULTS” are not needed for
diagnosis. In the case, “UNKWN” and “CAN COMM CIRCUIT [U1000]” in “Check sheet results (example)”
change to “–”. Then, ignore check marks on the check sheet table.

Perform system diagnosis for possible causes identified.

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