Installation and Post-Install Notes
Replacing the Savana 2500 Body Control Module is straightforward for a seasoned DIYer or any professional technician. After installation, some vehicles may require additional relearn procedures. For instance, if the airbag light is illuminated, 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. Always consult a factory service manual for your specific model’s requirements.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Do I need to have this module programmed?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN during checkout, and it will arrive ready to install with the latest software from GM.
Where is the BCM located on my 2010 Savana 2500 Van?
On most GMC Savana and Chevrolet Express vans from this era, the BCM is located behind the dashboard, typically in the center area, sometimes near the junction block.
What happens if I forget to provide my VIN?
We cannot program and ship your BCM without a valid VIN. The order will be placed on hold, and our team will contact you to retrieve the information needed to proceed with programming.
Will this fix my airbag light?
A faulty BCM can cause a false airbag light. Replacing it may resolve the issue, but some vehicles require an ‘Airbag System Sync’ procedure with a professional scan tool after installation to clear the light.
