U1000 CAN COMM CIRCUIT

Description

INFOID:0000000003135320

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.

BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000003757034

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.
