For step by step programming instructions, please refer to the techline information system (TIS) terminal.

Review the information below to make sure correct programming protocol.

Important: 

   • DO NOT program a control module unless you are directed by a service procedure or you are directed by a service bulletin. Programming a control module at any other time will not permanently correct a customer's 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, it is recommended to use one of the following external power sources:
      - A Midtronic PCS charger
      - A fully charged 12V jumper or booster pack disconnected from the AC voltage supply
   • Input requests across the GMLAN serial data circuits during recalibration can cause calibration issues. Due to the control modules common architecture, an inadvertent input may, in a rare instance, activate other control modules that have been commanded to remain silent during the recalibration of another control module possibly causing a programming event to fail.
   • Refrain from altering vehicle controls, opening and closing doors etc. while a control module is being recalibrated.
   • After a vehicle is shut down and the door is closed the vehicle will begin a power shut down process and it may take up to 40 minutes for all control modules to enter sleep mode, whereby the vehicle is drawing 35 - 40 ma of sleep power.
   • It is essential that the scan tool and the TIS terminal are both equipped with the latest software before performing service programming system (SPS).
   • 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.

Make sure the following conditions are met before programming a control module:

    • Vehicle system voltage
       - There is not a charging system concern, i.e battery voltage is greater than 12 volts but less than 16 volts. All charging system concerns must be repaired before programming a control module.
       - Battery voltage is greater than 12 volts but less than 16 volts.
       - Turn OFF or disable any system that may put a load on the vehicle's battery, such as the following components:
   • Twilight sentinel
   • Interior lights
   • Heating, ventilation, and air conditioning (HVAC) systems
   • Engine cooling fans, radio, etc.
    • The ignition switch must be in the correct position. The scan tool 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 scan 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 scan 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. Make sure 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.
