The Diagnostic Procedure described based on open circuit in spection. A short circuit inspection is also
required for the circuit check in the Diagnostic Procedure.
Is malfunctioning part detected?
YES >> GO TO 8
NO >> Check voltage of related BCM terminals using CONSULT.
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 9
9.FINAL CHECK
When DTC was detected in step 2, perform DTC C onfirmation Procedure or Component Function Check
again, and then check that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Is the inspection result normal?
NO (DTC is detected)>>GO TO 7
NO (Symptom remains)>>GO TO 6
YES >> Inspection End.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009461806
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communicati on speed and excellent error detection ability. Modern
vehicles are equipped with many electronic control uni ts, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with 2 communication lines (CAN H-line, CAN L-li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
CAN Communication Signal Chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
