DTC C1E11-97 or C1E91-97 (SENSOR BLOCKAGE, SOW DETECTS A BLOCKAGE)
may be stored as a past DTC. If any DTCs other than C1E11-97 or C1E91-97 are stored,
diagnose those DTCs before proceeding with this bulletin.
ACTION
1. Confirm the current ICC/ADAS 2 part number.
2. Reprogram the ICC/ADAS 2 and perform the blind spot warning action test, 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
ICC/ADAS 2 Reprogramming
IMPORTANT: Before starting, make sure:

ASIST on the CONSULT PC has been synchronized (updated) to the current date.

All CONSULT–III plus (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 CONSULT PC
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 C1E11-97 or C1E91-97, diagnose,
perform repairs, and erase DTCs before continuing.
1.
Connect the plus Vehicle Interface (plus VI) to the vehicle.

Make sure to use the correct VI for C-III plus (plus VI).
Make sure the plus VI is securly connected. If the plus 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.
2/20
NTB20-048a
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.
Make sure to turn OFF all external Bluetooth® devices. If Bluetooth® signal waves are
within range of the CONSULT PC and the plus 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.

The serial number will display when the plus VI is recognized.
