Revision:

For EV Involved Vehicles: The repairs outlined in this bulletin must only be completed at an authorized
EV dealer and repairs must be performed by a technician who has successfully completed the
applicable technical training required to perform this repair.
Involved vehicles will be repaired either through dealer repairs as described in this bulletin or through
over the air (OTA) programming. Dealers can and should perform the procedure in this bulletin on any
vehicle with an “open” status on the Investigate Vehicle History (IVH) screen in GM Global Warranty
Management system. Due to the fact that vehicles will be closed in IVH through successful OTA
programming, dealers should always check the status in IVH before performing any vehicle repairs.
Refer to Technical Service Bulletin 21-NA-043 for properly maintaining vehicles in dealer inventory.
This program is in effect until June 30, 2027.

* To avoid warranty transaction rejections, carefully read and follow the instructions below:

• The Warranty Claim Code from the programming event must be accurately entered in the “Warranty Claim
Code” field of the transaction.

•

When more than one Warranty Claim Code is generated for a programming event, it is required to document all
Warranty Claim Codes in the “Correction” field on the job card. Dealers must also enter one of the codes in the
“Warranty Claim Code” field of the transaction, otherwise the transaction will reject. It is best practice to enter
the FINAL code provided by SPS2.

Service Procedure
IMPORTANT: The following diagnostic verification MUST be performed before proceeding to programming.
1.

Using GDS2, verify U018B is NOT set current in any module.
1.1 If U018B is NOT set current, proceed immediately to the Programming section of this field action bulletin. After
programming, no further action is required.
1.2 If U018B IS set current, proceed to step 2.

6936331
2.

Perform a K183 UHF reset by removing Fuse 22DA in the X51 Instrument Panel Harness Junction Block. Refer to
Master Electrical Component List for fuse block location and information. While the fuse is removed, allow 30 minutes
for the K183 UHF to fully reset.

3.

Reinstall Fuse 22DA into the X51 Instrument Panel Harness Junction Block.

4.

Proceed to the Programming section of this bulletin.

Programming
Note: Carefully read and follow the instructions below.

•

Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector.
If there is an interruption during programming, programming failure or control module damage may occur.

•

Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will
interrupt programming. Install a GM Authorized Programming Support Tool to maintain system voltage. Refer to
www.gmdesolutions.com for further information. If not available, connect a fully charged 12 V jumper or booster
pack disconnected from the AC voltage supply. DO NOT connect a battery charger.

•

Follow the on-screen prompts regarding ignition power mode, but ensure that anything that drains excessive power
(exterior lights, HVAC blower motor, etc) is off.

•

Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.

Important: The service technician always needs to verify that the VIN displayed in the TLC left side drop down menu and
the top center window match the VIN plate of the vehicle to be programmed prior to using Service Programming System
2 (SPS2) for programming or reprogramming a module.

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 & Export
For dealers with involved vehicles, a listing has been prepared and will be available through GM Global Connect Maxis
Field Action Reports or sent directly to export dealers. 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.
Courtesy Transportation – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation
program details.
Customer Notification
USA & Canada - General Motors will notify customers of this program on their vehicle (see copy of sample customer letter
included with this bulletin).
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

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
assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your
vehicle may benefit from the information.

Your satisfaction with your vehicle is very important to us, so we are announcing a program to prevent this condition or,
if it has occurred, to fix it.
What We Will Do: Your GM dealer will reprogram the VKM with updated software to correct the condition. Owners
who have accepted the applicable terms and conditions may have already received the update with wireless over-theair OTA technology and will not have to bring their vehicle to a dealership. If you have not completed the update, follow
the in-vehicle radio prompts. Any owner having received this update through OTA technology will not have to bring their

service will be performed for you at no charge until June 30, 2027. After that, any applicable warranty will apply.
What You Should Do: To limit any possible inconvenience, we recommend that you contact your dealer as soon as
possible to schedule an appointment for this repair. When scheduling your appointment, confirm with the dealer that
they are an EV certified dealer.
