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.)
NOTE:
It is unnecessary to replace ABS actuator and electric unit (control unit) when “NG” on “INITIAL DIAG” of
“ABS” is indicated at this stage. “NG” is indicated not only when malfunctioning ABS actuator and electric
unit (control unit) but also other parts. See check sheet results for the system diagnosis.
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-10, "Example of Filling in Check Sheet When Ini-
tial Conditions Are Reproduced" .

When the initial conditions are not reproduced, refer to LAN-14, "Example of Filling in Check Sheet When
Initial Conditions Are Not Reproduced" .

Revision: 2006 December 2006 FX35/FX45
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 METER A/C AMP, AUTO DRIVE POS. and IPDM E/R because
METER A/C AMP, AUTO DRIVE POS. and IPDM E/R 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 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:
In “CAN DIAG SUPPORT MNTR” screen, “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 column of reception diagnosis of the check sheet table.

5. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen of “BCM” and “ABS” as well as “ENGINE”. And then, put a check mark to the check sheet table.
NOTE:

For “BCM”, “UNKWN” is displayed on “IPDM E/R”, “METER/M&A” and “I-KEY”. But, put a check mark
to “IPDM E/R” and “METER/M&A” because “UNKWN” is listed on the column of reception diagnosis of
the check sheet table.

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.

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” are displayed. Put a check mark to it.

For “BCM”, “NO DTC IS DETECTED” is displayed. Do not put a check mark to it.

For “METER A/C AMP”, “CAN COMM CIRCUIT [U1000]” are displayed. Put a check mark to it.

For “ABS”, “CAN COMM CIRCUIT [U1000]” are displayed. Put a check mark to it.

For “AUTO DRIVE POS.”, “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.
