  • With type B meter

    BCM Continuity
    Connector No. Terminal No.
    M18 26 27 Not existed

  • With type A meter

    BCM Continuity
    Connector No. Terminal No.
    M62 162 163 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 Ground Continuity
    Connector No. Terminal No.
    M18 26 Not existed
    27 Not existed

  • With type A meter

    BCM Ground Continuity
    Connector No. Terminal No.
    M62 162 Not existed
    163 Not existed

Is the inspection result normal?

YES>>

GO TO 6.

NO>>

Check the harness and repair or replace the root cause.

CHECK BCM AND IPDM E/R TERMINATION CIRCUIT

  1. Remove the BCM and the IPDM E/R.

  2. Check the resistance between the BCM terminals.

    • With type B meter

      BCM Resistance (Ω)
      Terminal No.
      26 27 Approx. 108 – 132

    • With type A meter

      BCM Resistance (Ω)
      Terminal No.
      162 163 Approx. 108 – 132

  3. Check the resistance between the IPDM E/R terminals.

    IPDM E/R Resistance (Ω)
    Terminal No.
    24 22 Approx. 108 – 132

Is the measurement value within the specification?

YES>>

GO TO 7.

NO>>

Replace the BCM and/or the IPDM E/R.

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 1 circuit.

    NOTE:

    BCM and IPDM E/R 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.

    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.
