VOLUNTARY SERVICE CAMPAIGN
2011-2015 LEAF; 2G TELEMATICS HARDWARE DEACTIVATION
This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Discard all previous versions of this bulletin.

CAMPAIGN ID #:

P7332

APPLIED VEHICLES: 2011-2015 LEAF (ZE0)
Refer to Service COMM to confirm campaign eligibility.

INTRODUCTION
Nissan is conducting a Voluntary Service Campaign (in the U.S. ONLY) on certain specific
2011-2015 LEAF vehicles equipped with 2G Telematics Hardware to disable the 2G
Telematics Control Unit (TCU). The 2G cellular service is no longer active in the United
States and the subject TCUs are no longer connected to telematics services (Nissan
Connect EVTM) and no longer perform any function in the affected vehicles. This campaign
is being performed out of abundance of caution to help prevent potential cybersecurity
issues.


Applied vehicles equipped with the 2G Telematics Control Unit (TCU) that enter the
service department for any reason should have the subject TCU deactivated. This
campaign will be performed at no charge to the customer for parts or labor.



For customers interested in the TCU update as opposed to deactivation, please refer
to NTB17-015.

IDENTIFICATION NUMBER
Nissan has assigned identification number P7332 to this campaign. This number must
appear on all communications and documentation of any nature dealing with this campaign.

DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.
Nissan 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 Nissan dealer to determine if this applies to your vehicle.
