SERVICE INFORMATION
The Applied Vehicles are equipped with a wireless communication device called a Telematics Communication
Unit (TCU). With an active Infiniti InTouch Services™ 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.
 A table has been provided on the next page that lists the model and year-specific steps required to
successfully configure a TCU after it has been replaced.
 A check OFF sheet has been provided on page 13 to print and check off steps as they are performed.
Please 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
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
customer keys collected.

The new/replacement TCU must come from Nissan North America parts supply.

TCU Configuration is required after replacement. Refer to step 14 on page 6.
Configuration must be done prior to performing Write VIN. If VIN is written 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.

Write VIN must be performed after the new/replacement TCU is installed in the vehicle.
