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 descr ibed 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 cabl e from the negative terminal.
3. Disconnect one of the unit connectors of CAN communication system.
