Service Programming System (SPS)
For step by step programming instructions, please refer to the techline information system (TIS) terminal.
Review the information below to ensure proper programming protocol.
| IMPORTANT | DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customers concern. It is essential that the Tech 2 and the TIS terminal are both equipped with the latest software before performing service programming system (SPS). Due to the time requirements of programming a controller, it is recommended that an external power source be used to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. To ensure trouble-free programming, GM recommends using one of the following external power sources: Midtronic PCS charger A fully charged 12V jumper or booster pack disconnected from the AC voltage supply Some modules will require additional programming/setup events performed before or after programming. Some vehicles may require the use of a CANDi 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. Turn OFF or disable any system that may put a load on the vehicles battery, such as the following components: Twilight sentinel Interior lights Daytime running lights (DRL)-Applying the parking brake, on most vehicles, disables the DRL system Heating, ventilation, and air conditioning (HVAC) systems Engine cooling fans, radio, etc.
- The ignition switch must be in the proper position. The Tech 2 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: The RS-232 communication cable port The connection at the data link connector (DLC) The voltage supply circuits
- DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
- DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. 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 cannot be programmed, replace the control module.
