Programming an Existing or New Control Module

WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

To program an existing or new control module, perform the following procedure:

  1. Install the special tool: EL-49642 SPS Programming Support Tool
  2. Ignition On/Vehicle In Service Mode
  3. Access SPS and follow the on-screen instructions for the control module: K71 Transmission Control Module - Programming
  4. After the programming is complete, select: Setup - If available

    If Setup is not available in SPS - Perform the appropriate learn/reset procedure with the scan tool

  5. Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to No.
