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

Diagnosis Procedure

CHECK CAN DIAGNOSIS

Check the CAN diagnosis results from CONSULT to see that the drivetrain CAN communication 2 circuit has no malfunction.

Is the drivetrain CAN communication circuit 2 normal?

GO TO 2.

Check and repair drivetrain CAN communication 2 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 drivetrain 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 ECM harness connector and the chassis control module harness connector.

• Without ProPILOT Assist 2.1

  ECM harness connector		Chassis control module harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  F72	30	B36	17	Existed
  	31		4	Existed

• With ProPILOT Assist 2.1

  ECM harness connector		Chassis control module harness connector		Continuity
  Connector No.	Terminal No.	Connector No.	Terminal No.
  F72	30	M32	20	Existed
  	31		3	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 ECM harness connector terminals.

Is the inspection result normal?

GO TO 5.

Check the harness and repair the root cause.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the ECM harness connector and the ground.

Is the inspection result normal?

GO TO 6.

Check the harness and repair the root cause.

CHECK TERMINATION CIRCUIT

1. Remove the ECM and the chassis control module.

2. Check the resistance between the ECM terminals.

   ECM		Resistance (Ω)
   Terminal No.
   30	31	Approx. 108 – 132

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

   • Without ProPILOT Assist 2.1

     Chassis control module		Resistance (Ω)
     Terminal No.
     17	4	Approx. 108 – 132

   • With ProPILOT Assist 2.1

     Chassis control module		Resistance (Ω)
     Terminal No.
     20	3	Approx. 108 – 132

Is the measurement value within the specification?

GO TO 7.

Replace the ECM and/or the chassis 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 drivetrain CAN 1 communication circuit.

   NOTE:

   ECM and chassis 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.
