Expert Technician’s Tip: Before you install your new 2013 GMC Sierra 2500 body control module, take a moment to inspect the main ground connections under the driver’s side door and on the engine block.

A little preventative maintenance goes a long way in ensuring the long-term health of your vehicle’s electrical system.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This allows for a straightforward, plug-and-play installation without the need for any additional dealership tools or fees.
What if my airbag light is on after installation?
If the airbag light persists (often with code B1001), it means the BCM needs to be synced with the airbag system’s SDM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool. It is not a sign of a defective part.
Where is the BCM located on my truck?
On most compatible models like the Silverado, Sierra, and Tahoe, the Body Control Module is located under the driver’s side of the dashboard, near the steering column. Installation typically takes less than 15 minutes.
Is this a reliable fix for my vehicle’s electrical issues?
Absolutely. A failing BCM is the root cause of many seemingly unrelated electrical problems. Replacing it with a properly programmed, high-quality unit like this one is the correct and definitive repair. This is the solution for a faulty 2013 GMC Sierra 2500 body control module.
Do I need to return my old part?
No, there is no core charge for this part. You can keep your old module without any hassle or extra fees.
