    Connector No. Terminal No.
    B26 87 86 Not existed

  • With type A meter

    BCM harness connector Continuity
    Connector No. Terminal No.
    B123 104 103 Not existed

Is the inspection result normal?

YES>>

GO TO 5.

NO>>

Check the harness and repair or replace the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the BCM and the ground.

  • With type B meter

    BCM harness connector Ground Continuity
    Connector No. Terminal No.
    B26 87 Not existed
    86 Not existed

  • With type A meter

    BCM harness connector Ground Continuity
    Connector No. Terminal No.
    B123 104 Not existed
    103 Not existed

Is the inspection result normal?

YES>>

GO TO 6.

NO>>

Check the harness and repair or replace the root cause.

CHECK BCM TERMINATION CIRCUIT

  1. Remove the BCM.

  2. Check the resistance between the BCM terminals.

    • With type B meter

      BCM Resistance (Ω)
      Terminal No.
      87 86 Approx. 108 – 132
      118 117 Approx. 108 – 132

    • With type A meter

      BCM Resistance (Ω)
      Terminal No.
      104 103 Approx. 108 – 132
      106 107 Approx. 108 – 132

Is the measurement value within the specification?

YES>>

GO TO 7.

NO>>

Replace the BCM.

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 Nissan Ariya vehicle CAN communication circuit 2.

    NOTE:

    BCM has two 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.
