SERVICE INFORMATION
On February 26, 2016 Nissan announced that it was sending a reminder notification to
owners affected by AT&T’s planned discontinuation of the 2G cellular network. At this time,
Nissan is beginning the process of making 3G compatible hardware available to owners of
affected vehicles as identified above. This upgrade may require an owner to make a copayment in order to receive the 3G hardware update. Please refer to the CLAIMS
INFORMATION below to determine if an owner co-pay is required. This customer
satisfaction initiative will cover some or all of the parts and labor cost required to upgrade
the vehicle’s telematics hardware to be 3G compatible.
You MUST use Service Comm to confirm bulletin Applicability.
Dealer’s Responsibility
It is the dealer’s responsibility to check SERVICE COMM using the appropriate Service
Comm I.D. for the status on each vehicle falling within the range of this customer
satisfaction initiative which for any reason enters the service department. If a vehicle
subject to this customer satisfaction activity was part of a dealer trade, the letter associated
with that vehicle should be forwarded to the appropriate dealer for upgrade completion.
NOTE:


Vehicle eligibility will be viewed on the second page of Service Comm. This activity
is not displayed on the main page of Service Comm because it is optional for
customers to participate.



Vehicles without Navigation are ineligible as they are not equipped with TCUs.

3. The notice for PC449 and PC450 on page 2 of Service Comm is not VIN specific and
does not disappear after a vehicle has been upgraded.
 Service Advisors should verify if the vehicle is still eligible for an upgrade before
informing a customer as follows:
Verify applicability using one of the following methods:
1. Check vehicle service history for previous repair (PC449 or PC450).
2. Check the TCU ID number on the vehicle information screen.
a. Press the hard button labeled Menu.
b. Press the “CARWINGS” soft button on the center display screen.
c. Press the “CARWINGS Settings” soft button on the center display screen.
d. Select the down arrow on the center display screen.
e. Press “Unit ID information” soft button on the center display screen.
f.

Look at the digit in the 5th position of the TCU ID number.


If the digit in the 5th position in the TCU ID is a “1” then it is a 3G TCU and
does not require an update



If the digit in the 5th position in the TCU ID is a number other than 1, it is a
2G TCU and requires replacement.

Figure 1

4. If applicable, dealers should ensure customers are informed of the 3G upgrade option
when bringing their vehicle in for service and that customers understand a co-pay
may be involved.
