LAN-48
< DTC/CIRCUIT DIAGNOSIS >
[CAN SYSTEM (TYPE 2)]
CAN COMMUNICATION CIRCUIT
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.
Inspection result
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 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.
