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.

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.
