For equivalent regional tools, refer to Special Tools .
For step-by-step control module programming instructions, please refer to the techline information system (TIS) terminal.
Review the information below to ensure proper programming protocol.
Note. DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors service bulletin. Programming a control module at any other time will not permanently correct a customers concern. It is essential that the TIS terminal, MDI, and/or Scan Tool, is equipped with the latest software before performing service programming. Due to the time requirements of programming a controller, install EL-49642 SPS Programming Support Tool to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. If the above tool is not available, DO NOT connect a battery charger, connect a fully charged 12V jumper or booster pack disconnected from the AC voltage supply. Some modules will require additional programming/setup events to be performed before or after programming. Some vehicles may require the use of a CANDi or MDI module for programming. Review the appropriate service information for these procedures. DTCs may set during programming. Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.
Ensure the following conditions are met before programming a control module
- Vehicle system voltage: There is not a charging system concern. All charging system concerns must be repaired before programming a control module. Battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully charged before programming the control module.

- The ignition switch must be in the proper position. SPS prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
- Make certain all tool connections are secure, including the following components and circuits: Scan Tool The RS-232 communication cable port The connection at the data link connector (DLC) The voltage supply circuits MDI The USB, Ethernet or Wireless communication port The connection at the data link connector (DLC)
- DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
In the event of an interrupted or unsuccessful programming event, perform the following steps
- DO NOT turn the ignition OFF. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date.
- Attempt to reprogram the control module.
- If the control module can still not be programmed, turn the ignition OFF for at least one minute.
- Turn the ignition ON and attempt to reprogram the control module. The control module should program. If the control module still cannot be programmed, replace the control module.
