TROUBLE DIAGNOSES WORK FLOWPFP:00004
When Displaying CAN Communication System ErrorsAKS00CBN
WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM

CAN communication line is open. (CAN H, CAN L, or both)

CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)

The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM

Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).

Fuse blown out (removed): CAN communication of the unit may be stopped at such time.

Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.

ACQUISITION OF DATA BY CONSULT-II
Attach the data acquired by CONSULT-II on the check sheet determined according to CAN system type.
(Transfer the data from the display screen of the vehicle to the CAN diagnosis monitor check sheet. For dis-
play unit: Refer to AV- 8 5 , "
CAN Communication Line Inspection" . For display control unit: Refer to AV- 1 5 5 ,
"CAN Communication Line Check" .)

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.
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-12, "Example of Filling in Check Sheet When Ini-
tial Conditions Are Reproduced" .

When the initial conditions are not reproduced. Refer to LAN-16, "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 AUTO DRIVE POS. and IPDM E/R because 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 “ICC”, “IPDM E/R” and “AWD/4WD/
e4WD”. But put a check mark to “IPDM E/R” because “UNKWN” is listed on the column of reception diag-
nosis 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 “AWD/4WD”. But, do not put a check mark to their columns of
reception diagnosis of the check sheet table because “UNKWN” is not listed.

4. Display unit reads the CAN diagnosis monitor check sheet (B) AV- 8 5 , "CAN Communication Line Inspec-
tion" transferred from the display screen (A). The transferred CAN diagnosis monitor check sheet is cop-
ied to the Check sheet, and conversed according to the Display unit Translation Sheet. And then put a
check mark to the check sheet table.
NOTE:
In the CAN diagnosis monitor check sheet (B), check marks are put to “CAN7”. But, in the column of the
check sheet table indication in Display unit Translation Sheet (C), “IPDM E/R” is listed only for “CAN7”.
Therefore, put a check mark to “IPDM E/R” because “UNKWN” is listed on the column of reception diag-
nosis 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”, “METER A/C AMP” 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” and “I-KEY”. But put a check mark to “IPDM E/R”
because “UNKWN” is listed on the column of reception diagnosis on the check sheet table.

For “METER A/C AMP”, “UNKWN” is not displayed. Do not put a check to it.

For “ABS”, “UNKWN” is displayed on “METER/M&A” and “ICC”. But, do not put a check mark to their
columns of reception diagnosis of the check sheet table because “UNKWN” is not listed.

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”, “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.
