Replacing the BCM is a straightforward process for a DIY mechanic or any professional technician. This module is designed as a direct-fit replacement for the original unit. After installation, some vehicles may require additional relearn procedures. For instance, if your airbag light illuminates, a ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control operation. These procedures are model-dependent but are standard for any BCM replacement.
This module is a direct replacement for a wide range of part numbers, including: 10382479, 15299986, 15828601, 15921352, 20815898, 22860591, 25892622, 25934763, and many more listed in the fitment data.

Frequently Asked Questions
What is a Body Control Module (BCM) and what does it do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic functions not related to the engine. This includes power windows, locks, lights, security system, wipers, and more. It acts as a central hub for these convenience and safety features.
Is this BCM truly plug-and-play?
Yes, for most vehicles. We program it to your VIN before shipping, which handles the most difficult part of the installation. In some cases, simple relearn procedures for systems like the airbag or brake pedal sensor may be required after installation, which can be done with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A technician with a professional diagnostic 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 your original module.
