Service Procedure
Caution: Carefully read and follow the instructions below.
• MDI2 is required to complete this programming event. To avoid module errors do NOT use MDI1.
• Programming the front camera module is required BEFORE completing the sequential module programming event.
There will be a “Successfully completed, press Finish!” pop up screen during the front camera module programming
event.
• Before completing the procedure, there will be a “Successfully completed, press Finish!” pop up screen. Disconnect the
front view camera module electrical connector for 10 seconds then reconnect the module and click “Finish” BEFORE 3
seconds have passed, or errors may occur. There is a small 3-5 second window of communication upon reconnect
therefore this may take multiple attempts.
• Contact TCSC if programming assistance is required.
Note: Carefully read and follow the instructions below.
• 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 12 V jumper or booster pack
disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including
daytime running lights), HVAC, etc.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system
status indicators to NO.
1. Remove the windshield multifunction sensor mount bracket. Refer to Windshield Multifunction Sensor Mount Bracket
Cover Replacement in SI.
Important: Important: Programming requires MDI2 ONLY. Using MDI WILL result in errors

* Important: To avoid warranty transaction rejections, carefully read and follow the instructions below:
• The SPS Warranty Claim Code must be accurately entered in the “SPS Warranty Claim Code” field 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” field on the job card. Dealers must also enter one of the codes in the “SPS
Warranty Claim Code” field of the transaction, otherwise the transaction will reject. It is best practice to enter the FINAL
code provided by SPS.
Warranty Claim Code Information Retrieval
If the SPS Warranty Claim Code was not recorded on the Job Card, the code can be retrieved in the SPS system as
follows:
1. Open TIS on the computer used to program the vehicle.
2. Select and start SPS.
3. Select Settings.
4. Select the Warranty Claim Code tab.
The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is

Reprogramming
GM Diagnostic/Programming (TIS2Web)
Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.
To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.
You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.
The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.
The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.
The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
