APPLIED SYSTEMS:
2020-2023 Titan/Titan XD (A61)
Automatic Emergency Braking/Forward Collision Warning
IF YOU CONFIRM
The customer states they have experienced false activation and/or unexpected braking of
the Automatic Emergency Braking (AEB) or Forward Collision Warning (FCW) system,
AND
There are no related DTCs stored.
ACTION
Follow the SERVICE PROCEDURE in this bulletin to:
1. Confirm the current ICC/ADAS part number.
2. Reprogram the ICC/ADAS, if applicable.
3. Configure the ICC/ADAS
4. Erase the DTCs.
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.
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
ICC/ADAS Reprogramming
IMPORTANT: Before beginning the following procedure, 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.
o Later in the procedure you will be required to enter your username and
password.
o The CONSULT PC must be connected to the internet.
o If you do not know your username and password, contact your service
manager.
1.

A screen print for warranty documentation can be done from the CONSULT PC
during this SERVICE PROCEDURE while still connected to the vehicle.

No diagnostic trouble codes (DTCs) are stored.
Connect the Vehicle Interface (VI) to the vehicle.

Make sure to use the correct VI for the CONSULT PC.
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 or 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.
4.
Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range
of the CONSULT PC and the VI.
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.
Start CONSULT-III plus on the CONSULT PC.
9.
If prompted, select USA/CANADA Dealers from the drop-down menu, and then
select OK.
10.
Login using your NNAnet credentials.
IMPORTANT: If not prompted to enter your username and password, the CONSULT
PC may not be connected to Wi-Fi. Close C-III plus, confirm the CONSULT PC is
connected to Wi-Fi, and then reopen C-III plus.
11.
Wait for the VI to be recognized (Figure 1).

The serial number will be displayed when the VI is recognized.
