Is the inspection result normal?

YES>>

GO TO 6.

NO>>

Check the harness and repair the root cause.

CHECK TERMINATION CIRCUIT

  1. Remove the 8CH CAN gateway and the ECM.

  2. Check the resistance between the 8CH CAN gateway terminals.

    • With type B meter

      8CH CAN gateway Resistance (Ω)
      Terminal No.
      7 6 Approx. 108 – 132

    • With type A meter

      8CH CAN gateway Resistance (Ω)
      Terminal No.
      43 42 Approx. 108 – 132

  3. Check the resistance between the ECM.

    ECM Resistance (Ω)
    Terminal No.
    132 131 Approx. 108 – 132

Is the measurement value within the specification?

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.

  1. Turn the ignition switch OFF.

  2. Disconnect the battery cable from the negative terminal.

  3. 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.

  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.

CHECK WARNING LAMP

  1. Turn the ignition switch ON.

  2. Check the engine oil pressure warning lamp.

Is the inspection result normal?

YES>>

INSPECTION END

NO>>

Replace the 8CH CAN gateway.
