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™ subscription, 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.
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.

TURNING ON THE TCU DURING PDI
NOTE:

This procedure is for 2013-2017 Applied Vehicles ONLY.

In most instances, the TCU is ON when delivered to the dealership. See the steps below to determine if
the TCU is ON or OFF.
1. With the vehicle in an area of known good reception, turn the ignition ON
and check whether or not the green light on the SOS button is illuminated
(see Figure 1a).
Light not
illuminated
NOTE: It may be difficult to tell if the green light is illuminated if the
vehicle is outside in bright sunlight.

If the green light is illuminated, the process to turn ON the TCU is
complete and no further action is needed.

If the green light is not illuminated, go to Turn ON TCU on the next
page.
Figure 1a
2. After the TCU is turned ON, check whether or not the green light on the SOS button is illuminated.

If the green light is still not illuminated, verify the vehicle is unsold.
 If the vehicle has been sold, the customer will need to be enrolled in Infiniti Connection® or
Infiniti InTouch Services™ for the SOS light to be illuminated and for Infiniti Connection® or
Infiniti InTouch Services™ to be enabled.
 Refer to SOS Light Diagnosis Information on page 23.
3. Perform steps to Check TCU Cellular Reception - see page 7.
4
Turn the ignition OFF.
5. Pull OUT the extended storage switch to return the vehicle to shipping mode.
NOTE: If the “Turning ON the TCU During PDI” procedure is not followed correctly, the vehicle cannot be used
in Dealer Demo mode or enrolled in Infiniti Connection® or Infiniti InTouch Services™. Should this occur, the
“Turning ON the TCU During PDI” process will need to be performed again.
