This Ultium Software Update bulletin is being suspended. Many of the above
vehicles now fall under different Customer Satisfaction Field Actions that will
improve the customer experience and optimize future Over-The-Air updates.
The Labor Operations below will only be valid for Repair Orders dated June 14th,
2024 and prior.
Condition

This direction outlined in this PIT regarding updating all modules should no
longer be practiced. Updating specific modules should be the result of following
Service Information or a Bulletin/PI when addressing a customer complaint.
In the near future, a new programming process will be rolled out that will provide
a more streamlined procedure for updating all modules when customers come to
the dealership for specific vehicle issues. When that process is available,
additional direction will be provided on whole vehicle modules updates.

Review Open Field Actions for affected vehicles before continuing diagnosis:
2024 Silverado EV - Refer to N242435430: Customer Satisfaction Program Multiple Module Reprogramming.

Correction

2023 Cadillac LYRIQ - Refer to N232428540: Customer Satisfaction Program Multiple Module Reprogramming.
2024 Cadillac LYRIQ - Refer to N232425350: Customer Satisfaction Program Image Processing Module Software Update
*For 2024 LYRIQ's, please review PIE0768 prior to performing any software
updates.

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.
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 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.
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 window and use these for programming or reprogramming the subject
module with the correct vehicle VIN and software and/or calibrations.
The Engine Control Module (ECM) is the master module (for VIP 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 ECM also needs to be reprogrammed with the correct VIN, software and calibrations that
match the vehicle’s VIN plate.
The Body Control Module (BCM) is the master module (for GEM 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.

1. Start programming the first module listed on the SPS2 supported controllers table (3).

Important: If the same calibration/software warning is noted on the TLC Summary screen like the example
below. Select OK and follow screen instructions.

After a successful programming event, the WCC is located in the Service Programming System dialogue box
of the SPS Summary screen.
Document the WCC on the job card and proceed to the next module.
Refer to the Warranty Information section of this bulletin.

Note: The screenshot above is 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.
2. Record the SPS Warranty Claim Code on the job card for warranty transaction submission.
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. Refer to callout 1 above for the
location of the WCC on the screen.
3. After successfully programming the module select “Proceed with same VIN” to continue
programming the rest of the vehicle.
4. Repeat the steps above for the next modules to verify all have the latest software going down the
list (4).

5. Use GDS2 to clear any DTCs after successfully programming.

Warranty Claim Code Information Retrieval

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.

Warranty Information
Important: The following Labor Operations will only be valid for Repair Orders dated June 14th, 2024 and
prior.
For vehicles repaired under the Bumper-to-Bumper coverage (Canada Base Warranty coverage), use the
following labor operations. Reference the Applicable Warranties section of Investigate Vehicle History (IVH)
for coverage information.
If a module requires updating, utilize the following labor operations and time for claim payment. Only
modules requiring an update should be claimed. Claim payment for the Software Maintenance
Reprogramming labor operation will be based on .3 hours base time plus the add time for each additional
module that requires programming.
If the Image Processing Module requires programming, a separate labor operation should be submitted
utilizing straight time for the base time.
Note: The following Add times are for normal programming events. If there are issues with programming,
Other Labor Hours should be utilized for the additional time.
Important: The following Labor Operations will only be valid for Repair Orders dated June 14th, 2024 and
prior.
