Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means the module is delivered ready to install right out of the box. We flash the unit with your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software before shipping. This ensures it communicates perfectly with your truck’s other computers, like the ECU and instrument cluster, eliminating the need for a costly programming service at a dealership.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back.
My airbag light is on after installation. What should I do?
This can happen occasionally. If the airbag warning light is on, a procedure called “Setup SDM Primary Key in BCM” needs to be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and will turn off the light.
Is this a difficult part to install myself?
For most models, this is a very straightforward installation. The BCM is typically located under the steering column. The process usually involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors to the new module. Most people can complete the job in under 10 minutes with basic hand tools.
Will this BCM fix my specific electrical problem?
This module is the central hub for all body-related electronics. If you are experiencing issues with multiple systems like power locks, windows, radio, and interior lights simultaneously, the BCM is the most likely culprit. This VIN programmed 15116066 body control module is designed to resolve those exact issues.
How can I be sure my BCM is the problem?
While the symptoms listed are strong indicators, the best way to be 100% certain is a professional diagnosis with a high-end scan tool that can communicate with the BCM and check for specific trouble codes. Common codes pointing to a faulty BCM include B1001 or various “U” codes indicating a loss of communication.
