Diagnosis Procedure

CHECK CAN DIAGNOSIS

Check the CAN diagnosis results from CONSULT to see that the drivetrain CAN communication 2 circuit has no malfunction.

Is the drivetrain CAN communication circuit 2 normal?

YES>>

GO TO 2.

NO>>

Check and repair drivetrain CAN communication 2 circuit.

CONNECTOR INSPECTION

  1. Turn the ignition switch OFF.

  2. Disconnect the battery cable from the negative terminal.

  3. Disconnect all the unit connectors on engine CAN communication circuit.

  4. Check terminals and connectors for damage, bend and loose connection.

Is the inspection result normal?

YES>>

GO TO 3.

NO>>

Repair the terminal and connector.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the ECM harness connector and the electric intake valve timing control module harness connector.

ECM harness connector Electric intake valve timing control module harness connector Continuity
Connector No. Terminal No. Connector No. Terminal No.
E21 146 F113 3 Existed
145 1 Existed

Is the inspection result normal?

YES>>

GO TO 4.

NO>>

Check the harness and repair the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the ECM harness connector terminals.

ECM harness connector Continuity
Connector No. Terminal No.
E21 146 145 Not existed

Is the inspection result normal?

YES>>

GO TO 5.

NO>>

Check the harness and repair the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the ECM harness connector and the ground.

ECM harness connector Ground Continuity
Connector No. Terminal No.
E21 146 Not existed
145 Not existed

Is the inspection result normal?

YES>>

GO TO 6.

NO>>

Check the harness and repair the root cause.

CHECK TERMINATION CIRCUIT

  1. Remove the ECM and the electric intake valve timing control module.

  2. Check the resistance between the ECM terminals.

    ECM Resistance (Ω)
    Terminal No.
    146 145 Approx. 108 – 132

  3. Check the resistance between the electric intake valve timing control module terminals.

    Electric intake valve timing control module Resistance (Ω)
    Terminal No.
    3 1 Approx. 108 – 132

Is the measurement value within the specification?

YES>>

GO TO 7.

NO>>

Replace the ECM and/or the electric intake valve timing control module.

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.

  1. Turn the ignition switch OFF.

  2. Disconnect the battery cable from the negative terminal.

  3. Disconnect one of the unit connectors of engine CAN communication circuit.

  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.
