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

Diagnosis Procedure

CHECK CAN DIAGNOSIS

Check the CAN diagnosis results from CONSULT to see that the chassis CAN communication 4 circuit have no malfunction.

Are the chassis CAN communication 4 circuit normal?

GO TO 2.

Check and repair chassis CAN communication 4 circuit.

CONNECTOR INSPECTION

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect all the control unit connectors on chassis CAN communication 1 circuit.

4. Check the 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 chassis control module harness connector and power steering control module harness connector.

• Without ProPILOT Assist 2.1

  Chassis control module harness connector		Power steering control module harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  B36	3	E31	2	Existed
  	16		1	Existed

• With ProPILOT Assist 2.1

  Chassis control module harness connector		Power steering control module harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  M32	18	E111	2	Existed
  	2		1	Existed

Is the inspection result normal?

GO TO 4.

Check the harness and repair or replace the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the chassis control module harness connector terminals.

• Without ProPILOT Assist 2.1

  Chassis control module harness connector			Continuity
  Connector No.	Terminal No.
  B36	3	16	Not existed

• With ProPILOT Assist 2.1

  Chassis control module harness connector			Continuity
  Connector No.	Terminal No.
  M32	18	2	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 chassis control module and the ground.

• Without ProPILOT Assist 2.1

  Chassis control module harness connector		Ground	Continuity
  Connector No.	Terminal No.
  B36	3		Not existed
  	16		Not existed

• With ProPILOT Assist 2.1

  Chassis control module harness connector		Ground	Continuity
  Connector No.	Terminal No.
  M32	18		Not existed
  	2		Not existed

Is the inspection result normal?

GO TO 6.

Check the harness and repair or replace (if shield line is short) the root cause.

CHECK CHASSIS CONTROL MODULE AND POWER STEERING CONTROL MODULE TERMINATION CIRCUIT

1. Remove the chassis control module and the power steering control module.

2. Check the resistance between the chassis control module terminals.

   • Without ProPILOT Assist 2.1

     Chassis control module		Resistance (Ω)
     Terminal No.
     3	16	Approx. 108 – 132

   • With ProPILOT Assist 2.1

     Chassis control module		Resistance (Ω)
     Terminal No.
     18	2	Approx. 108 – 132

3. Check the resistance between the power steering control module terminals.

   Power steering control module		Resistance (Ω)
   Terminal No.
   2	1	Approx. 108 – 132

Is the measurement value within the specification?

GO TO 7.

Replace the chassis control module and/or the power steering 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

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 chassis CAN communication 1 circuit.

   NOTE:

   Chassis control module and power steering control module 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

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

Replace the unit whose connector was disconnected.
