Nissan Rogue (T33) 2021-Present Service Manual: Vehicle Can Communication 1 Circuit

Diagnosis Procedure

CHECK NETWORK DIAGNOSIS

Check the "Network diagnosis" results from CONSULT to see that the Nissan Ariya vehicle CAN communication 4 circuit and diagnostic CAN communication circuit have no malfunction.

Are the Nissan Ariya vehicle CAN communication 4 circuit and diagnostic CAN communication circuit normal?

GO TO 2.

Check and repair Nissan Ariya vehicle CAN communication 4 circuit and/or diagnostic CAN communication 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 Nissan Ariya vehicle CAN communication 1 circuit.

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

Is the inspection result normal?

GO TO 3.

Repair the terminal and connector.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the BCM harness connector and the IPDM E/R harness connector

• With type B meter

  BCM harness connector		IPDM E/R harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  M18	26	E120	24	Existed
  	27		22	Existed

• With type A meter

  BCM harness connector		IPDM E/R harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  M62	162	E120	24	Existed
  	163		22	Existed

Is the inspection result normal?

GO TO 4.

Check the harness and repair the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the BCM terminals.

• 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?

GO TO 5.

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?

GO TO 6.

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?

GO TO 7.

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

GO TO 8.

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

Connect the connector. Check other units as per the above procedure.

Replace the unit whose connector was disconnected.
