1.

STEERING ANGLE SENSOR NEUTRAL POSITION ADJUSTMENT

Perform the steering angle sensor neutral position adjustment.

CAUTION:

Perform the steering angle sensor neutral position adjustment on VDC side. VDC may activate incor-
rectly.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000000962460

CAN (Controller Area Network) is the serial transmission for real time application. CAN is the multiplex com-
munication for the vehicle with superior data transmission speed and error detection ability. Many electronic
control units are equipped on the vehicle. These control units do not operate individually, but associates with
other control units by sharing information. In CAN communication, each control unit is connected with two
communication lines (CAN-H and CAN-L). Much information is transmitted with fewer communication lines
than before. Each control unit transmits/receives data and reads the necessary data only.

LAN-28, "CAN Communication Signal Chart"

Diagnosis Procedure

INFOID:0000000000962462

1.

PERFORM SELF DIAGNOSTIC

1.

Turn ignition switch ON and wait for 2 seconds or more.

2.

Check “Self Diagnostic Result”.

Is “CAN COMM CIRCUIT” displayed?

YES

>> Refer to 

LAN-18, "Trouble Diagnosis Flow Chart"

.

NO

>> Refer to 

GI-39, "Intermittent Incident"

.

DTC detection condition

DTC erase condition

Possible causes

When AFS control unit does not transmit/receive CAN com-
munication signal continuously for 2 seconds or more

Ignition switch OFF

One or more following items of CAN com-
munication system are error.
• Transmission
• Reception (ECM)
• Reception (Unified meter and A/C amp.)
• Reception (TCM)
• Reception (Steering angle sensor)
• Reception (IPDM E/R)

BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000000962464

1.

CHECK FUSE AND FUSIBLE LINK

Check that the following fuse and fusible link are not blown.

Is the fuse fusing?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connectors.

3.

Check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> INSPECTION END

NO

>> Repair harness or connector.

BCM (BODY CONTROL MODULE) : Special Repair Requirement

INFOID:0000000000962465

1.

REQUIRED WORK WHEN REPLACING BCM

Initialize IVIS by CONSULT-III. For the details of initialization refer to CONSULT-III operation manual NATS-
IVIS/NVIS.

>> Work end.
