Involved Region or Country All Regions
Electric Vehicles (EV) contain signi cant number of Electronic Modules that may require software
updates.
Condition

These software updates are important to not only x issues, but also enhance the vehicle functions.
For the e ected customer owned vehicles above, GM is recommending that dealers check each module
for software updates and perform updates anytime a ected vehicles are brought in for service.
Technicians are to utilize SPS2 on Techline Connect to check for updates on every module.

Correction

*For 2023 LYRIQ's, please review PIE0779 prior to performing any software updates.
*For 2024 LYRIQ's, please review PIE0768 prior to performing any software updates.

Service Procedure
Caution: Before downloading the update les, be sure the computer is connected to the internet through a network cable
(hardwired). DO NOT DOWNLOAD or install the les 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 uctuation, 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 o .
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 rst 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 speci c 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. 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
eld.

Warranty Information

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.
