SERVICE INFORMATION
The APPLIED VEHICLES are equipped with a wireless communication device called a Telematics
Communication Unit (TCU). The TCU communicates with the Infiniti 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 system for the APPLIED VEHICLES.

An Order of Completion 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 on page 16. Print and check off steps as they are
completed. Staple the completed CHECK-OFF SHEET to the repair order.
Infiniti 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 Infiniti retailer to determine if this
applies to your vehicle.

TCU REPLACEMENT
HINT: Each TCU is registered to a specific Vehicle Identification Number (VIN). TCUs cannot be “swapped”
between vehicles. Once a TCU is registered to a vehicle, the TCU cannot be used in another vehicle.
IMPORTANT:

During this procedure, Intelligent Key Registration must be performed. You MUST have ALL client
keys collected.

The new/replacement TCU must come from Nissan North America parts supply.

TCU configuration is required after replacement. Refer to step 15 on page 6.
Configuration must be completed prior to performing the Write the VIN to the TCU procedure. If performed
prior to configuration, the TCU may not function properly and might need replacement. The warranty claim will
be denied if this is not followed correctly.

The Write the VIN to the TCU procedure must be performed after the new/replacement TCU is
installed in the vehicle.
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 VI. If Bluetooth® signal waves are within range of the CONSULT PC or VI
during reprogramming, the reprogramming may be interrupted.

Turn OFF all vehicle electrical loads.

Turn ON the hazard warning lights.

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.
