• The Warranty Claim Code and Total Time 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.

Warranty Claim Code Information Retrieval

6693878

If the Warranty Claim Code was not recorded on the Job Card, the code can be retrieved in the SPS2 system as
follows:
1.
2.
3.
4.

Open TLC on the computer used to program the vehicle.
Select and start SPS2.
Select Settings (1).
Select the Warranty Claim Code tab (2).

The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is
retrievable, dealers should resubmit the transaction making sure to include the code in the SPS Warranty Claim Code
field.
Service Procedure
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.
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 Vehicle Wide 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.

•

For the TLC application, service technicians need to always ensure that the power mode (ignition) is “ON” before
reading the VIN from the vehicle’s VIN master module and that they do not select a VIN that is already in the TLC
application memory from a previous vehicle.

•

If the VIN that shows up in the TLC top center window after correctly reading the VIN from the vehicle does not match
the VIN plate of the vehicle, manually type in the VIN characters from the vehicle VIN plate into the TLC top center

Customer Satisfaction Program
N242436170 Multiple Module Reprogramming
window and use these for programming or reprogramming the subject module with the correct vehicle VIN and
software and/or calibrations.

•

The Body Control Module (BCM) is the primary module (for VIP EV vehicles) that TLC reads to determine the VIN of
the vehicle. If the VIN read from the vehicle by TLC does not match the VIN plate of the vehicle, the BCM also needs
to be reprogrammed with the correct VIN, software and calibrations that match the vehicle’s VIN plate.

Caution: Be sure the VIN selected in the drop-down menu (1) is the same as the vehicle connected (2) before beginning
programming.

5743643

Important: If the vehicle VIN DOES NOT match, the message below will be shown.

5877000

5644477

Important: Techline Connect screens shown above.
Important: Vehicle Wide Programming will only work with a wired MDI2 connection. It is also necessary to
remove any wireless dongles from the computer being used as these will not allow the Vehicle Wide

Customer Satisfaction Program
N242436170 Multiple Module Reprogramming
Programming to be selectable. If the Vehicle Wide Programming is not selectable with a wired MDI2,
confirm it shows disconnected in SPS2 and then (if needed) exit out of TLC and log-in again.
Important: It is critical to remove ALL aftermarket devices connected to the DLC and all USB devices
connected to the vehicle USB ports. Additionally, all wireless Bluetooth USB connectors (mouse,
keyboard,etc) MUST be disconnected from the computer prior to opening Techline Connect.
Important: After Radio USB programming is complete, verify the software version on Radio Screen
matches the current version shown on the Warranty Claim Code (WCC) screen in Techline Connect (TLC).
Refer to the WCC screen for instructions on how to navigate to the software version within the Radio menu.
1.

Within SPS, perform the following steps for the A11 Radio. Refer to A11 Radio Programming and Setup in SI:
1.1 Prepare for USB File Transfer
1.2 USB File Transfer

2.

Perform Vehicle Wide Programming. Refer to: 24-NA-113 in SI. Please read the bulletin in its entirety prior to
programming the vehicle.

3.

Verify all applicable modules display “SUCCESS” or “SKIPPED”, excluding the A11 Radio which is NOT supported
by Vehicle Wide Programming and was manually updated in the previous steps.
•

If any applicable module does NOT display “SUCCESS” or “SKIPPED”:
3.1 Attempt Vehicle Wide Programming a second time.
3.2 If any applicable module fails the second attempt, attempt to program the module
individually through SPS. If the failure continues, contact Techline Customer Service Center.
3.3 Perform Vehicle Wide Programming an additional time to receive a “Status Completed” or
“Status Blocked” message, allowing the field action to be closed. Proceed to step 4.

•

If all modules have successfully updated, proceed to step 4.

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

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 GlobalConnect 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.
