SERVICE INFORMATION
The Applied Vehicles are equipped with a wireless communication device called a Telematics Communication
Unit (TCU). With an active Infiniti Connection® or 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 21 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. HINT: 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.
