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.

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.

• Prior to starting any programming, all aftermarket

devices should be removed from the DLC and

USB devices disconnected from the USB ports.

• 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 discon-
Bulletin No.: 24-NA-113

nected 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.

• 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.

1. 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.

done. The Vehicle-Wide Programming Summary report

will indicate any other modules needing separate

programming once VWP is complete.

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 fields for installation.
• Programming: Installing updated software into the modules.

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.

Programming Status:
Warranty Information
• 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).
For information on submitting Vehicle Wide

Programming field action claims, please refer to

Warranty Administration Bulletin (24-NA-132).
• Blocked: An overall status of blocked will appear

if all modules were already up to date and no

actual programming was attempted.
Warranty Claim Code Information Retrieval
• 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.
6693763
If the Warranty Claim Code was not recorded on the

Job Card, the code can be retrieved in the SPS2

system as follows:

1. Open TLC on the computer used to program the

vehicle.

2. Select and start SPS2.

3. Select Settings (1).

4. 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.
Potential New Techline Errors

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.

Performing a Field Action

Important: A field action is not considered complete

until all modules have been noted as up to date.

When performing a field action, the following steps

should be performed.

1. Perform Vehicle-Wide Programming (VWP)

process as outlined.

• If all modules are up to date, proceed to step 2.

• If any module (outside of radio) did not program

or is not up to date, attempt Vehicle-Wide

Programming a second time.
− 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, proceed to Step 2.

2. Update the radio through standalone update

through SPS2 (as needed).

Important: A field action will only close if all modules

are shown as up to date through a programming

attempt.
− If all modules are up to date, proceed to step

2.
