Incorrect Control Module

WARNING: This page is about a different car, the 2017 GMC Acadia Limited, 2017 Chevrolet Traverse, and 2017 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

There are only a few situations where reprogramming a control module is appropriate:
- A new service control module is installed.
- A control module from another vehicle is installed.
- Revised software/calibration files have been released for this vehicle.

NOTE:

DO NOT re-program the control module with the SAME software/calibration files that are already present in the control module. This is not an effective repair for any type of concern.

Verify that the control module contains the correct software/calibration. If incorrect programming is found, reprogram the control module with the most current software/calibration. Refer to Control Module References for replacement, setup, and programming.
