Reprogram Control Module

To reprogram an existing control module, perform the following procedure:

  1. Delete any paired devices in the Paired Phones List (Home>> Config>> Phone Settings>> Bluetooth) to prevent potential interruptions during the USB and SPS programming events outlined below.
  2. Install the EL-49642  SPS Programming Support Tool.
  3. Connect a USB drive to the computer.
    NOTE:

    If using a pre-configured USB drive supplied by General Motors, proceed to step 6.

  4. Access the Service Programming System (SPS) and follow the on-screen instructions.
  5. On the SPS Supported Controllers screen, select A11 Radio - USB File Transfer, and follow the on-screen instructions.
    NOTE:
    • If there are no files available for USB transfer via SPS, proceed to step 11.
    • All existing files on the USB drive will be erased when the new files are copied.
  6. Upon completion of the file transfer, remove the USB drive from the computer.
  7. Turn ON the ignition and radio so audio is playing with the engine OFF.
  8. Connect the USB drive to the USB port in the vehicle.
  9. If a "No Music Files Found" message is displayed, press OK.
  10. Using the radio controls, select the following: Config>Radio Settings>Software Versions Menu>Update Radio Software. Follow the infotainment display on-screen instructions and select Update when prompted.
    NOTE:
    • A "Searching and verifying" message will be displayed for up to 20 minutes, this is normal. Once the searching and verifying message is gone, a "Press the Key Sequence" screen may be displayed, DO NOT press Cancel if displayed. It is important to press the displayed button press sequence on the screen to start the update. This requires the displayed button press sequence to be followed in proper order. Please note that each button press requires a momentary press of the right "seek up" or left "seek down" button. If any wrong key presses occur, it may be necessary to start the USB programming process over again by removing the USB stick and reinserting it in order to do a Search & Verify again. If this does not restart the Search & Verify process, it may be necessary to remove the radio fuse for 30 seconds, re-insert the fuse, and start the USB programming process again.
    • Once the USB programming starts, a series of files will be installed as evidenced by a progress bar and "file 1 of 5, file 2 of 5, etc." messages or similar messages depending on year, model, and software. As these files are installing, it is normal to experience a momentary blank screen, loss of audio, and/or "splash screen" after/during installation of file 4 of 5. Do not interrupt programming if this is noted - please be patient and allow programming to completely finish. Typically this step will take 30-60 minutes to complete as USB files 1-5 are installed into the radio.
  11. When programming is complete, remove the USB device from the vehicle USB port.
  12. Access the Service Programming System (SPS) and follow the on-screen instructions.
  13. On the SPS Supported Controllers screen, select A11 Radio - Programming, and follow the on-screen instructions.
  14. At the end of programming, choose the "Clear DTCs" function on the SPS screen. The radio must be reset as well by pressing the following radio buttons: Config>Radio Settings>Software Versions Menu>Clear and Reset Radio. Select "Yes" to reset the radio. Upon completion of this step, the radio will restart and you can allow the radio to resume normal operation again.
