Condition
Some customers may receive a field action indicating the use or programming.
GM’s latest electrical architecture design contains a significant number of Electronic Modules that may
require software updates.
These software updates are important to not only fix issues, but also enhance the vehicle functions.
As opposed to programming modules individually, Vehicle Wide Programming (VWP) allows technicians to
select a single button to program all modules to their latest version in parallel reducing overall programming
time.
Cause
The cause of the condition may be software anomalies.
Correction
Technicians are to utilize SPS2/SPS3 on Techline Connect to check for updates.
Service Procedure
Note: The use of Vehicle Wide Programming (VWP) should only be attempted at the direction of Field Action unless the vehicle is specifically covered by the
latest version of 24-NA-143 (Software Update on Ultium Vehicles).
Important: If there needs to be a Module Replacement then program the single module first prior to Vehicle Wide Programming.
Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws applicable to the activities it performs
under this bulletin, including but not limited to handling, deploying, preparing, classifying, packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you must
follow those applicable laws.
Important: This technical service bulletin (TSB) can only be completed by certified repair facilities who have met all specific training, tool and equipment
requirements pertaining to the vehicle Brand and Model serviced. Repairs must be performed by a technician who has successfully completed the required
training.
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.
Description:
Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to
first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in
parallel instead of forcing the technician to update one module at a time. This allows a more streamlined approach reducing technician time and number of
required steps.
•
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.
Note: 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 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 SPS2 and log-in again.
•
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 12V 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.
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 window and use these for programming or reprogramming the
subject module with the correct vehicle VIN and software and/or calibrations.
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.
2
1.
Prior to starting any programming, all aftermarket devices should be removed from the DLC and USB devices disconnected from the USB ports. Open
SPS2 and enter job card number, then click next.
2.
To complete a VWP event, click on the blue button on the right side. If unable to select, verify wired MDI2 connection and that there are no wireless
dongles in the computer as stated above.
3
3.
A SPS3 page will open and VWP will begin.
Below is a description of each Techline Connect bar.
•
•
•
•
Retrieving Data from Vehicle: During this step, Techline Connect is retrieving current software information from the vehicle.
Retrieving Data from Sever: Utilizing the VIN information, Techline Connect is retrieving the latest software information from General Motors.
Downloading: Performs comparison and downloads required files for installation.
Programming: Installing updated software into the modules.
4
4.
Once complete, a Vehicle-Wide Programming Summary screen will appear. This will list all modules that are up to date or may require to updated still. It
will also advise of any failures. While it is saved automatically, it is recommended for the tech to print/capture anything noted as failed or out of date
before exiting the screen. It will also advise to check the VCU separately as it is not included in VWP today.
5
5.
Once complete, the warranty claim code page will populate with details of a completed, partial, or failed programming event. Any failures will be shown at
the top highlighted in red. Any successful or skipped modules will be collapsed but are viewable in a printout or clicking on an individual carrot.
6
Programming Status:
•
Completed: Event indicates that all control modules were successfully programmed (Some of the modules could show skipped if the module
already had the latest software).
•
•
•
•
Blocked: An overall status of blocked will appear if all modules were already up to date and no actual programming was attempted.
Partial: Status indicates that at least one control module failed to program. Failed control modules will be highlighted in red.
Failed: Indicates that all control modules failed to program.
Skipped: Individual control modules indicate that the module is up to date and no further programming needed.
Important: If a failed programming event happens, VWP should be repeated one time prior to utilizing SPS 2 to program the affected Module(s). A
separate warranty code will be displayed.
6.
For all Modules that are not supported by VWP (see step #4), complete their programming utilizing SPS2 application.
7.
Use GDS2 to clear any DTCs after successfully programming.
Note: The screenshots above are an example of module programming and may not be indicative of the specific module that is being programmed.
Module selection and VIN information have been blacked out.
Important: To avoid warranty transaction rejections, you MUST record the warranty claim code provided on the Warranty Claim Code (WCC) screen
shown above on the job card.
Note: If either of the following errors are received, this indicates a Techline connection concern. The recommended course of action is to exit from TLC
completely and try again. If either failure persists, reboot the machine.
7
Performing a Field Action
Important: A "Status Completed" or "Status Blocked" message must be displayed in order to close out the Field Action. Any other status will NOT satisfy the
Field Action and the Field Action will NOT close out.
When performing a field action, the following steps should be performed.
1.
Update the radio through standalone update through SPS2 ONLY if instructed by the Field Action bulletin. NOT all Vehicle-Wide Programming
(VWP) Field Action bulletins require radio programming.
2.
Perform Vehicle-Wide Programming (VWP) process as outlined.
8
•
•
If all modules are up to date, please follow the warranty claim code retrieval process as outlined in the Warranty Information section.
If any module (outside of radio) did not program or is not up to date, attempt Vehicle-Wide Programming a second time.
–
If all modules are up to date, please follow the warranty claim code retrieval process as outlined in the Warranty Information section.
–
If a module still has a failure or is not up to date after this second try, use SPS2 to attempt to program and diagnose as needed. Once
completed, please follow the warranty claim code retrieval process as outlined in the Warranty Information section.
Important: A field action will only close if all modules are shown as up to date through a programming attempt.

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 equipment, tools,
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 GM dealer for information on whether your vehicle may benefit from the information.
