CAN COMMUNICATION CIRCUIT 1

Diagnosis Procedure

INFOID:0000000011506845

1.

CONNECTOR INSPECTION

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect all the unit connectors on CAN communication circuit 1.

4. Check terminals and connectors for damage, bend and loose connection.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the data link connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair or replace (if shield line or fuse block (J/B) is short) the root cause.

3.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the data link connector and the ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check the harness and repair or replace (if shield line or fuse block (J/B) is short) the root cause.

4.

CHECK ECM AND BCM TERMINATION CIRCUIT

1. Remove the ECM and the BCM.

2. Check the resistance between the IPDM E/R terminals.

3. Check the resistance between the BCM terminals.

Is the measurement value within the specification?

YES

>> GO TO 5.

NO

>> Replace the ECM and/or the BCM.

5.

CHECK SYMPTOM

Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with

customer)” are reproduced.

Reproduced>>GO TO 6.

Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is

detected.

6.

CHECK UNIT REPRODUCTION

Perform the reproduction test as per the following procedure for each unit.

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect one of the unit connectors of CAN communication circuit 1.

NOTE:

ECM and BCM have a termination circuit. Check other units first.

4. Connect the battery cable to the negative terminal. Check if the symptoms described in the “Symptom

(Results from interview with customer)” are reproduced. 

NOTE:

Although unit-related error symptoms occur, do not confuse them with other symptoms. 

Inspection result

Reproduced>>Connect the connector. Check other units as per the above procedure.

Non-reproduced>>Replace the unit whose connector was disconnected.

Diagnosis Procedure

INFOID:0000000011506846

1.

CONNECTOR INSPECTION

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the BCM for damage, bend and loose connection (unit side and

connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of BCM.

2. Check the continuity between the BCM harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair or replace the root cause.

3.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

1. Disconnect all the unit connectors on CAN communication circuit 2.

2. Check the continuity between the BCM harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check the harness and repair or replace the root cause.

4.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the BCM and the ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Check the harness and repair or replace (if shield line is short) the root cause.

5.

CHECK BCM TERMINATION CIRCUIT

1. Remove the BCM.

2. Check the resistance between the BCM terminals.
