Replace and Program Control Module or Reprogram Control Module

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 GMC Yukon XL, 2015 GMC Yukon, 2015 Chevrolet Tahoe, 2015 Chevrolet Suburban, and 2015 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.

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

Install EL-49642 SPS Programming Support Tool.
Access the Service Programming System (SPS) and follow the on-screen instructions.
On the SPS Supported Controllers screen, select K4 Assist Step Control Module - Programming and follow the on-screen instructions.
NOTE:
If during programming a message is displayed that the same calibration is attempting to be installed, select OK to proceed - this process will also program the VIN.
At the end of programming, choose the "Clear All DTCs" function on the SPS screen.
Open and close both the driver and passenger door to verify operation. Doors may need to opened and closed two times for the assist step control module to learn the board home positions.
