YES>>GO TO 7.
NO (ECM)>>With type B meter: Replace the ECM.
NO (8CH CAN gateway)>>With type B meter: GO TO 9.
NO>>With type A meter: Replace the 8CH CAN gateway and/or the ECM.
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 8.
Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is detected.
CHECK UNIT REPRODUCTION
Perform the reproduction test as per the following procedure for each unit.
-
Turn the ignition switch OFF.
-
Disconnect the battery cable from the negative terminal.
-
Disconnect one of the unit connectors of drivetrain CAN communication 2 circuit.
NOTE:
8CH CAN gateway and ECM have a termination circuits. Check other units first.
-
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.
CHECK WARNING LAMP
-
Turn the ignition switch ON.
-
Check the engine oil pressure warning lamp.
Is the inspection result normal?
YES>>INSPECTION END
NO>>Replace the 8CH CAN gateway.
