SERVICE INFORMATION
The vehicles listed under APPLIED VEHICLES that come equipped with a factory installed
SOS switch, located near the overhead map lamp, also come equipped with a wireless
communication device called a Telematics Communication Unit (TCU). With an active
NissanConnect Services™ subscription, the TCU communicates with the Nissan Data
Center to provide various security and convenience services.
This bulletin contains important service procedures that must be performed properly in
order to set up and maintain the telematics/in-vehicle communications (IVC) system for the
vehicles listed under APPLIED VEHICLES.

A table has been provided, on the next page, that lists the steps required to
successfully configure a TCU after it has been replaced.

A check-off sheet has been provided in this bulletin to print and check off steps as
they are completed. Staple the completed check-off sheet to the repair order.
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.

TCU REPLACEMENT
To avoid damage to the vehicle, only install new, unused TCUs into a vehicle. Each TCU is
registered to a specific VIN and will not function if swapped into another vehicle.
IMPORTANT:

During this procedure, Intelligent Key registration must be performed. You MUST
have ALL customer Intelligent Keys collected.

The new/replacement TCU must come from Nissan North America parts supply.

TCU configuration is required after replacement. Refer to step 13 on page 7.
Configuration must be done prior to performing Write VIN. If Write VIN is performed prior to
configuration, the TCU may not function properly and might need replacement.
NOTE: The warranty claim will be denied if this is not followed correctly.
Perform the following before saving the VIN data and configuration to prevent damage to
the TCU.

Connect the AC Adapter to the CONSULT PC.

Connect the CONSULT PC to the Internet via Wi-Fi or a network cable.

Ensure ASIST on the CONSULT PC has been synchronized (updated) to the current
date and all C-III plus software updates (if any) have been installed.

Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.) within
range of the CONSULT PC and the plus VI. If Bluetooth® signal waves are within
range of the CONSULT PC or plus VI during reprogramming, the reprogramming
may be interrupted.

Turn OFF all vehicle electrical loads.

Turn ON the hazard warning lamps.

Connect a battery maintainer or smart charger, set to reflash mode or a similar
setting, to ensure the battery voltage stays between 12.0 V and 15.5 V.
