System 2 (SPS2) for programming or reprogramming a module.
IMPORTANT: Failure to follow all notes and cautions within the programming and setup document may result in
programming errors.
Caution: Before downloading the update files, be sure the computer is connected to the internet through a network
cable (hardwired). DO NOT DOWNLOAD or install the files wirelessly. If there is an interruption during programming,
programming failure or control module damage may occur.

Dealer Responsibility
All new, used, GM Certified Pre-Owned (CPO), courtesy transportation vehicles, dealer shuttle vehicles, CarBravo, etc.
in dealers' possession and subject to this field action must be held and inspected/repaired per the service procedure of
this bulletin before customers take possession of these vehicles. Involved vehicles must be held and not delivered to
customers, dealer-traded, released to auction, used for demonstration, or any other purpose.
All GM Certified Pre-Owned (CPO) vehicles currently in the dealers’ inventory within the SHIFT Digital system will be
de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid
warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within
the SHIFT Digital system, or once again be used in the Courtesy Transportation Program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through the end date as noted in the Attention box. Customers who have recently purchased vehicles sold
from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle listing, are
to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions
contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers.
Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the
notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service
through the end date as noted in the Attention box, you must take the steps necessary to be sure the program correction
has been made before selling or releasing the vehicle.
Dealer Reports – For USA
For dealers with involved vehicles, a listing has been prepared and will be available through GM Global Connect Maxis
Field Action Reports or GWM Field Action Batch Search Report. The Inventory tab of the dealer reports will contain
VINs that apply to this field action. This information is intended to assist dealers with the PROMPT COMPLETION of
these vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle
Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary
to complete this field action may be a violation of law in several states.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT

vehicle may benefit from the information.
