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
1.

Confirm the current ICC/ADAS 2 part number.

2.

Reprogram the ICC/ADAS 2, 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
Reprogram the ICC/ADAS 2
IMPORTANT: Before starting, make sure:

1.



ASIST on the CONSULT PC has been synchronized (updated) to the current date.



All CONSULT-III plus software updates (if any) have been installed.



During the reprogramming process, you will receive some errors. These errors are
expected. Please follow all of the steps in this procedure to successfully complete
the reprogramming process.



Connect a battery maintainer or smart charger set to reflash mode or a similar
setting. If the vehicle battery voltage drops below 12.0V or rises above 13.5V
during reprogramming, the ICC/ADAS 2 control module may be damaged.



Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains
ON, the ICC/ADAS 2 control module may be damaged.



Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops
during reprogramming, the process will be interrupted and the ICC/ADAS 2 control
module may be damaged.



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 or VI during reprogramming, reprogramming may be
interrupted and the ICC/ADAS 2 control module may be damaged.

Connect the Vehicle Interface (VI) to the vehicle.


Make sure to use the correct VI for the CONSULT PC.

2.

Turn the ignition ON with the engine OFF.

3.

Turn ON the hazard warning lamps.

4.

Start C-III plus.

5.

If prompted, select USA/CANADA Dealers from the drop down menu, and then
select OK.

6.

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.
