Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this BCM truly plug-and-play?
Because we program it to your VIN, it is as close to plug-and-play as possible and will not require a trip to the dealer for initial programming. However, on some vehicles, secondary procedures like an airbag system sync or brake pedal position relearn may be necessary using a professional scan tool to ensure all systems function correctly.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. Your VIN can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What if my airbag light is on after installation?
If the airbag light illuminates after installing the new BCM, it simply means the BCM and the airbag system (SDM) need to be synchronized. A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep or dispose of your original module.
How do I know this fits my vehicle?
This module fits a wide variety of GM vehicles like the Chevy Impala, GMC Acadia, Cadillac DTS, and many more. The best way to confirm fitment is to match the part number from your original BCM to one of the numbers listed in our description.
