Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, these systems can become unreliable.
Is this BCM difficult to install?
No, the physical installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column and can often be swapped in under 5 minutes with basic tools. Since our module comes pre-programmed, no complex computer work is needed for most vehicles.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and configurations onto the BCM. This ensures all features and options your truck or SUV came with from the factory work correctly. Without it, the module won’t be able to communicate properly with other computers in the vehicle, leading to system malfunctions.
What if my airbag light is still on after installation?
In some cases, particularly if you had an airbag code like B1001, a final sync procedure is required. This is called an ‘SDM Primary Key Setup’ and must be performed with a professional-grade scan tool. It’s a quick procedure for a mechanic to complete and syncs the new BCM with the airbag system.
How do I know if this will fit my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs like the Silverado, Sierra, Tahoe, and Escalade. The best way to confirm is to match your original part number to one of the many interchangeable numbers listed in the description, such as 25971916, 25844480, or 22860591. You can also use our website’s fitment tool for verification.
Is there a core charge for this part?
No, there is absolutely no core charge. You are not required to send your old BCM back to us, which simplifies the repair process for you.
