Nissan Rogue (T33) 2021-Present Service Manual: Chassis Can Communication 3 Circuit

Diagnosis Procedure

CHECK CAN DIAGNOSIS

Check the "Network Diagnosis" results from CONSULT to see that the ITS CAN communication 1 circuit, ITS CAN communication 4 circuit and diagnostic CAN communication circuit have no malfunction.

Are the ITS CAN communication 1 circuit, ITS CAN communication 4 circuit and diagnostic CAN communication circuit normal?

GO TO 2.

Check and repair ITS CAN communication 1 circuit, ITS CAN communication 4 circuit and/or diagnostic CAN communication circuit.

CONNECTOR INSPECTION

1. Ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect all the control unit connectors on chassis CAN communication 3 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 ADAS control unit 2 harness connector and power steering control module.

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 ADAS control unit 2 harness connector terminals.

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 ADAS control unit 2 and the ground.

Is the inspection result normal?

GO TO 6.

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

CHECK ADAS CONTROL UNIT 2 AND POWER STEERING CONTROL MODULE TERMINATION CIRCUIT

1. Remove the ADAS control unit 2 and the power steering control module.

2. Check the resistance between the ADAS control unit 2 terminals.

   ADAS control unit 2		Resistance (Ω)
   Terminal No.
   14	34	Approx. 108 – 132

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

   Power steering control module		Resistance (Ω)
   Terminal No.
   10	9	Approx. 108 – 132

Is the measurement value within the specification?

GO TO 8.

Replace the ADAS control unit 2 and/or the power steering control module.

• ADAS control unit 2: Removal and Installation

• Power steering control module (steering gear and linkage): Removal and Installation

CHECK CAN DIAGNOSIS

Check the CAN diagnosis results from CONSULT to see that the chassis CAN communication 4 circuit, chassis CAN communication 6 circuit and diagnostic CAN communication circuit have no malfunction.

Are the chassis CAN communication 4 circuit, chassis CAN communication 6 circuit and diagnostic CAN communication circuit normal?

GO TO 8.

Check and repair chassis CAN communication 4 circuit, chassis CAN communication 6 circuit and/or diagnostic CAN communication circuit.

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 9.

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. Ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect one of the unit connectors of chassis CAN communication 3 circuit.

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.
