Post-Installation Information
After installing your new 2001 Sierra BCM, some vehicles may require additional steps to ensure all systems are synchronized. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on 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: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How do I provide my VIN for programming?
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, as we program the module specifically for your vehicle.
Is this part difficult to install?
The BCM is typically located under the driver’s side dashboard. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It is a manageable job for a DIYer with basic tools, but you must be aware of the potential post-installation procedures.
Will this fix my specific electrical problem?
A faulty BCM is the cause of many common electrical issues. While this part will resolve problems caused by a failed BCM, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module.
What if my airbag light comes on after I install it?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
