Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls a wide variety of electronic functions not related to the engine. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and sometimes even the radio and climate controls. It acts as a central hub for these systems.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the installation is straightforward. The BCM is typically located under the dashboard, either in the center or under the steering column. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, please note that post-installation procedures, like an airbag system sync or brake pedal position relearn, may be required and need a professional scan tool.
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it. This ensures the module is a perfect match for your vehicle’s specific configuration.
Do I need to send my old part back?
No. This product has no core charge. You can keep, recycle, or dispose of your original module as you see fit. This simplifies the process for you.
What if my airbag light is on after installation?
If the airbag warning light is on after you install the new BCM, it means the module needs to be synchronized with the vehicle’s airbag system (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a standard security step on many GM vehicles.
