HOW TO USE CHECK SHEET TABLE
1. Unit names displayed on CONSULT-II
2. “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)
3. “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.)
4. “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.
“–”: Column not used (Transmit diagnosis is not performed.)
5. “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.)
When the initial conditions are reproduced. Refer to LAN-15, "Example of Filling in Check Sheet When Ini-
tial Conditions Are Reproduced" .
When the initial conditions are not reproduced. Refer to LAN-18, "Example of Filling in Check Sheet When
Initial Conditions Are Not Reproduced" .

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 BCM and AUTO DRIVE POS. because BCM and AUTO DRIVE
POS. is not displayed 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” and
“IPDM E/R”. 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” and “AIR PRESSURE MONITOR” 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” and “METER/M&A” because “UNKWN” is listed on the col-
umn of reception diagnosis of the check sheet table.
For “AIR PRESSURE MONITOR”, “UNKWN” is displayed on “ECM”. Put a check mark to it.

4. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen
of “INTELLIGENT KEY”, “METER A/C AMP”, “MULTI AV”, “ABS” and “IPDM E/R” as well as “ENGINE”.
And then, put a check mark to the check sheet table.
NOTE:
For “INTELLIGENT KEY”, “UNKWN” is displayed on “ECM”, “BCM/SEC” and “TCM”. Put a check mark
to it.
For “METER A/C AMP”, “UNKWN” is displayed on “ECM”, “TCM” and “BCM/SEC”. Put a check mark to
it.
For “MULTI AV”, “UNKWN” is displayed on “ECM” and “BCM/SEC”. Put a check mark to it.
For “ABS”, “UNKWN” is displayed on “ECM”, “TCM”, “METER/M&A”, “ICC” and “AWD/4WD”. But put a
check mark to “ECM” and “TCM” because “UNKWN” is listed on the column of reception diagnosis of
the check sheet table.
For “IPDM E/R”, “UNKWN” is displayed on “ECM” and “BCM/SEC”. Put a check mark to it.

NOTE:
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.
5. Perform system diagnosis for possible causes identified.
6. 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. Refer to LAN-34, "
CAN Communica-
tion Unit" .

Example of Filling in Check Sheet When Initial Conditions Are Not Reproduced
1. See “SELF-DIAG RESULTS” of all units attached to the check sheet. If “CAN COMM CIRCUIT [U1000]”
or “CAN COMM CIRCUIT [U1001]” is displayed, put a check mark to the applicable column of self-diag-
nostic results of the check sheet table.
NOTE:
For “ENGINE”, “CAN COMM CIRCUIT [U1001]” are displayed. Put a check mark to it.
For “A/T”, “CAN COMM CIRCUIT [U1000]” are displayed. Put a check mark to it.
For “BCM”, “CAN COMM CIRCUIT [U1000]” is displayed. Put a check mark to it.
For “AIR PRESSURE MONITOR”, “CAN COMM CIRCUIT [U1000]” is displayed. Put a check mark to it.
For “INTELLIGENT KEY”, “CAN COMM CIRCUIT [U1000]” is displayed. Put a check mark to it.
For “METER A/C AMP”, “CAN COMM CIRCUIT [U1000]” are displayed. Put a check mark to it.
For “MULTI AV”, “CAN COMM CIRCUIT [U1000]” is displayed. Put a check mark to it.
For “AUTO DRIVE POS.”, “NO DTC IS DETECTED” are displayed. Do not put a check mark to it.
For “ABS”, “CAN COMM CIRCUIT [U1000]” are displayed. Put a check mark to it.
For “IPDM E/R”, “CAN COMM CIRCUIT [U1000]” is displayed. Put a check mark to it.
