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-

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.

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.
