Installation and Post-Install Steps
Installation is typically straightforward. On Silverado and Sierra pickups, the BCM is located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s found in the center of the dash. While the module is plug-and-play for most functions, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the instrument cluster.
Do I need to take this part to a dealer for programming?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you a trip to the dealership and additional programming fees.
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 ship your order until we receive this information for programming.
What if my airbag light comes on after I install the BCM?
This can happen on some vehicles. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Where is the BCM located on my vehicle?
On 2003-2007 Silverado and Sierra pickups, it is typically found under the dashboard on the driver’s side. On Express and Savana vans, it’s usually located behind the center dash panel.
