Service Procedure
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 con ict between the procedures set
forth in this bulletin and the laws that apply to your dealership, you must follow those applicable laws.
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 12 V 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.
Important: If the vehicle VIN DOES NOT match, the message below will be shown
Important: Techline Connect screens shown above.
Important: If the same calibration/software warning is noted on the TLC Summary screen, 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. No further action is required. Refer to the Warranty section of the bulletin.
1. Reprogram the Engine Control Module. Refer to K20 Engine Control Module: Programming and Setup.
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.
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.
2. Record SPS Warranty Claim Code on job card for warranty transaction submission.
Warranty Information
For vehicles repaired under the Emission coverage, use the following labor operation. Reference the Applicable
Warranties section of Investigate Vehicle History (IVH) for coverage information:
Labor Operation
2889348
Description
Reprogram ECM for Turbocharger Calibration
*This is a unique Labor Operation for Bulletin use only.
Labor Time
0.3 Hr.
Important: Warranty coverage code E2 applies for this module programming event. ECM reprogramming is covered
for 8 years/80,000 miles (U.S.) or 8 years/130,000 km (Canada).
Important: **To avoid warranty transaction rejections, carefully read and follow the instructions below:
• The Warranty Claim Code must be accurately entered in the “Warranty Claim Code” eld of the transaction.
• When more than one Warranty Claim Code is generated for a programming event, it is required to document all
Warranty Claim Codes in the “Correction” eld on the job card. Dealers must also enter one of the codes in the
“Warranty Claim Code” eld of the transaction, otherwise the transaction will reject. It is best practice to enter the
FINAL code provided by SPS2.
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
