Installation and Post-Install Considerations
Installation is straightforward for most DIY mechanics. The BCM is typically located under the driver’s side dashboard, near the steering column. In most cases, the process takes less than 15 minutes. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light appears after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This re-establishes the security handshake between the BCM and the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and stability control function.

Frequently Asked Questions
Is this BCM ready to install right out of the box?
Yes. We pre-program the module using the VIN you provide during checkout. This ensures it is plug-and-play and requires no additional programming from a dealership for standard operation.
Where is the BCM located on my 2013 Sierra?
The Body Control Module is typically found under the driver’s side dashboard, often attached to a bracket near the steering column or the main fuse panel.
What does the ‘Setup SDM Primary Key’ procedure do?
This is a security procedure that syncs the new BCM with your vehicle’s existing airbag control module (SDM). It’s only necessary if the airbag warning light comes on after you’ve installed the new BCM.
Will this fix my intermittent power window and door lock issues?
A failing BCM is one of the most common causes of these specific issues. If you’ve already checked fuses and wiring, replacing the BCM is the most likely solution to restore proper function to your power accessories.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module without any extra fees or hassle.
