Frequently Asked Questions (FAQ):
Q.

Will this be a campaign?

A.

Additional information will be the subject of a future announcement. NissaneBay logo plans to send further
information in summer 2016.

Q.

AT&T has announced plans to discontinue its 2G cellular network coverage on
December 31, 2016. How does this affect my access to NissanConnect EV (formerly
CARWINGS)?

A.

Like all devices, including vehicles, equipped to connect to a cellular network on the 2G access
band, NissaneBay logo LEAF models with a 2G telematics control unit (TCU) will be unable to use or receive
services from that device after 12/31/16. Without an upgrade to the TCU, NissanConnect EV
features will not be available after that date and may be affected prior to that date depending
upon AT&T’s proprietary decisions regarding 2G network coverage.

Q.

What is 2G cellular network access?

A.

2G means “Second Generation” and refers to digital cellular telephone technology; it is the name
of a specific network that mobile telephone equipment uses to provide connectivity.

Q.

What vehicles are affected by this issue? How do I know if this issue affects me?

A.

NissaneBay logo will contact affected customers directly; customers can contact NissaneBay logo LEAF Owner
Services at 1-877-664-2738 to verify if your vehicle requires upgrading.
The following models are equipped with 2G TCUs:
 All model years 2011-2015,
 Model 2016 LEAF is equipped with 3G TCU hardware and is not affected

Q.

Will the new TCU hardware work with 4G cellular network?

A.

The new TCU hardware will be equipped current 3G cellular network technology.

Q.

Why is NissaneBay logo using 3G technology rather than 4G?

A.

NissaneBay logo has studied how to integrate newer technology into your vehicle and developed solutions
aimed at delivering a minimally invasive repair with the least inconvenience to customers. The 3G
network is supported throughout the U.S. by AT&T and is expected to continue for years to come.

Q.

When can I get a replacement Telematics Control Unit (TCU)?

A.

NissaneBay logo will communicate with affected customers with additional information regarding options for
upgrading the TCU hardware in their vehicles once the hardware is readily available.

Q.

Why must I enroll in NissanConnect EV before June 30, 2016?

A.

AT&T will suspend new enrollments in NissanConnect EV after June 30, 2016. If a NissaneBay logo LEAF
with 2G equipment is purchased prior to June 30, 2016, the owner should be enrolled in
NissanConnect EV on or prior to that date to ensure enrollment is able to be processed.

Q.

What happens if I do not replace the TCU?

A.

Once the 2G cellular network is discontinued, the TCU will no longer be able to access the
NissanConnect EV telematics program features including Remote State of Charge and Climate
Control.

Q.

How much will the replacement TCU cost and when will the costs be provided?

A.

Pricing of the replacement TCU is not yet available, however NissaneBay logo plans to communicate the
options for equipment upgrades for affected customers subscribed or wanting to subscribe to the
NissanConnect EV telematics program in late summer 2016.

Q.

Will vehicle owners have to pay for the replacement TCU?

A.

NissaneBay logo is planning to offer support to all affected customers with a 2G equipped vehicle who are
using NissanConnect EV.

Owners of 2011-14 model year LEAF vehicles will be asked to contribute to the labor and
parts cost of the hardware upgrade.

For owners of 2015 model year LEAF vehicles currently enrolled or choosing to use
NissanConnect EV, NissaneBay logo plans to pay for the labor and parts cost of the upgraded TCU
hardware.
