Restore Full Control Over Your Truck’s Electronics
Are you dealing with frustrating and unpredictable electrical problems in your GM truck or SUV? One moment the power windows work, the next they don’t. Maybe the security light is flashing for no reason, or the interior lights have a mind of their own. These are classic signs of a failing Body Control Module (BCM), the central computer for your vehicle’s body electronics. Instead of dealing with the high costs and programming hassles at a dealership, get the simple, reliable solution that gets your truck back to work.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of confusing issues. If you’re experiencing any of the following, this module is the definitive fix:

- Erratic interior or exterior lighting behavior.
- A flashing security light that may prevent the vehicle from starting (PassLock issues).
- Problems with the radio or instrument cluster functions.
- False warning lights on the dashboard.

An Expert’s Insight on Early 2000s GM BCMs
As a technician, I’ve seen countless GMT800 platform trucksโthe Silverados, Sierras, Tahoes, and Suburbans of this eraโcome into the shop with bizarre electrical issues. The original BCMs were susceptible to failure from thermal stress on the circuit board and sometimes moisture intrusion. A common mistake is grabbing a used BCM from a salvage yard. While it might plug in, it won’t work correctly because it’s programmed for the donor vehicle’s options and security system. Our Programmed BCM 9371990 completely bypasses that problem, giving you a part that is not only tested and reliable but is also digitally matched to your specific truck before it even leaves our facility. It’s the smart, professional way to do the job right the first time.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require one or more of the following procedures to sync all systems perfectly:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
Please Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your truck’s specific options, such as power windows, keyless entry, and security system. This makes the installation plug-and-play.
Is this a difficult part to replace?
For most of the compatible vehicles, the BCM is located under the driver’s side of the dashboard. It typically requires removing a lower dash panel for access. Basic hand tools are all that’s needed for the physical swap, which usually takes less than an hour.
What happens if the airbag light comes on?
If the airbag light illuminates after installation, it means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This requires a professional-grade scan tool with GM-specific functions to perform the ‘Setup SDM Primary Key’ procedure. Many independent repair shops can perform this service.
Will this fix my ‘Security’ light issue?
Yes, a faulty BCM is a very common cause of PassLock security system problems on these GM vehicles. A properly Programmed BCM 9371990 will restore the security system to normal operation.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment part that has been expertly programmed for your vehicle. It is guaranteed to restore your vehicle’s function.
How do I send you my VIN?
After you complete your purchase, please send us a message with your 17-digit VIN. We cannot ship your order until we receive this information.
