WARNING: This page is about a different car, the 2024 GMC Terrain and 2024 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

To program a replacement or an existing ECU, perform the following procedure:

  1. Access the Service Programming System (SPS) and follow the on-screen instructions.
  2. On the SPS Supported Controllers screen, select P16 Instrument Cluster - Programming and follow the on-screen instructions.
  3. On the SPS Supported Controllers screen, select P16 Instrument Cluster - Setup and Configuration and follow the on-screen instructions.
    4. NOTE:
    • The USB File Transfer procedure requires the use of a USB memory stick. The radio must be on during this procedure. The USB File Transfer procedure is not required for vehicles with UDC.
    • Software currently loaded on the USB Drive will be verified and if files are incorrect they will be deleted and correct files will be loaded. If files residing on the USB Drive are correct for the vehicle being serviced, the Techline terminal will not delete those files and allow the drive to be re-used.
    • The USB File Transfer procedure is normally performed with the Ignition ON/Vehicle in Service Mode. If USB File Transfer fails in Ignition ON/Vehicle in Service Mode, attempt USB File Transfer again with the engine running.
  4. On the SPS Supported Controllers screen, select P16 Instrument Cluster - USB File Transfer and follow the on-screen instructions.
  5. At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
