This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Please discard previous versions of this bulletin.
APPLIED VEHICLE:
2021 Rogue (T33)
IF YOU CONFIRM
Any of the following DTCs are stored:

B2740-87 (TCU)

B2744-87 (BCM)

B274D-87 (Combination Meter)
ACTION
Reprogram the Sonar Control Unit, if applicable.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
Sonar Control Unit Reprogramming
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current
date.

All C-III plus software updates (if any) have been installed.

The CONSULT PC is connected to the internet via a cable or Wi-Fi.
 Later in the procedure you will be required to enter your username and
password.
 The CONSULT PC must be connected to the internet.
 If you do not know your username and password, contact your service
manager.

A screen print for warranty documentation can be done from the C-III plus during
this service procedure while still connected to the vehicle.

No Diagnostic Trouble Codes (DTCs) are stored.
 Use C-III plus to perform Self Diagnosis for all systems.
 If there are any DTCs, other than B2740-87, B2744-87 and/or B274D-87,
diagnose, perform repairs, and erase DTCs before continuing.
1.
Connect the VI to the vehicle.
Make sure the VI is securely connected. If the VI connection is loose during
reprogramming, the process will be interrupted and the control unit may be
damaged.
2.
Connect the AC Adapter to the CONSULT PC.
Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops
during reprogramming, the process will be interrupted and the control unit may be
damaged.
3.
Connect a battery maintainer/smart charger set to reflash mode or a similar setting.
To avoid damage to the control unit, ensure a battery maintainer or smart charger is
connected. The battery voltage must be between 12.0V and 15.5V during
reprogramming.
2/27
NTB21-040A
4.
Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range
of the CONSULT PC and VI.
Make sure to turn OFF all external Bluetooth® devices. If Bluetooth® signal waves
are within range of the CONSULT PC and the VI during reprogramming,
reprogramming may be interrupted and the control unit may be damaged.
5.
Turn the ignition ON with the engine OFF.
To avoid damage to the control unit, the engine must not start or run during the
reprogramming procedure.
6.
Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC,
blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
7.
Turn ON the hazard warning lamps.
8.
Turn ON the CONSULT PC.
9.
Start C-III plus.
