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.
- HR16DE models
- MR16DDT models
- K9K models
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.
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.
