Don’t let these electrical gremlins ruin your driving experience. This is your direct, plug-and-play solution.

Installation & Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the steering column or in the center dash area. After installation, no core return is necessary, so you can keep your original module. In some cases, minor post-installation procedures may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
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, such as power windows, locks, lights, wipers, security system, and interior chimes.
Is this part ready to install when I receive it?
Yes! This BCM comes fully programmed to your vehicle’s VIN. Simply provide your VIN after purchase, and we’ll flash the module with the latest GM software so it’s ready for installation upon arrival.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
What if my airbag light comes on after I install the BCM?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s SDM. A qualified technician with a professional diagnostic tool can 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.
