Diagnosis Procedure
INFOID:0000000009760138
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 system.
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 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 the root cause.
4.
CHECK ECM AND BCM TERMINATION CIRCUIT
1. Remove the ECM and the BCM.
2. Check the resistance between the ECM 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.

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 system.
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:0000000009760139
1.
CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the following terminals and connectors for damage, bend and loose connection (connector side
and harness side).
-
Harness connector E7
-
Harness connector M69
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair the terminal and connector.
2.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the following harness connectors.
-
IPDM E/R
-
Harness connectors E7 and M69
2. Check the continuity between the IPDM E/R harness connector and the harness connector.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair the main line between the IPDM E/R and the harness connector E7.
3.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of around view monitor control unit.
2. Check the continuity between the harness connector and the around view monitor control unit harness
connector.
Is the inspection result normal?
YES (Present error)>>Check CAN system type decision again.
YES (Past error)>>Error was detected in the main line between the harness connector M69 and the around
view monitor control unit.
NO
>> Repair the main line between the harness connector M69 and the around view monitor control
unit.
