Restore Your Vehicle’s Electrical System with a Plug-and-Programmed BCM
Are strange electrical issues turning your reliable GM truck or SUV into a source of daily frustration? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are all common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and annoying problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and security. Get back to a vehicle you can trust with our direct-replacement, VIN-programmed Body Control Module.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing BCM is the likely culprit:
- Intermittent or non-working power windows, door locks, or mirrors.
- Interior dome lights or dashboard lights staying on or not working at all.
- Erratic behavior from the anti-theft or keyless entry system.
- Warning lights on the dash such as the airbag or brake light.
- Communication errors with other vehicle modules (DTC U-codes).

We take the most difficult step out of the equation.

Expert Insight: The Diagnostic Shortcut
We often see customers who have spent hundreds of dollars chasing what they think are separate issues. For example, a 2010 Suburban came in with a non-functional driver’s side window and an intermittent no-start condition tied to the security system. The owner had already replaced the window switch. The real culprit was a single point of failure: the BCM. By replacing it with a properly flashed unit like this Programmed Body Control Module 15948439, both problems were solved at once, saving the owner from further diagnostic headaches and unnecessary part replacements.
Important Note on Installation: While this module is pre-programmed, some vehicles may require a simple ‘relearn’ procedure after installation for systems like the brake pedal position sensor or the airbag system (if the warning light is on). These procedures are outlined in your service manual or can be performed by any qualified technician with a capable scan tool. This Programmed Body Control Module 15948439 is the core of the repair, and we handle that for you.
Frequently Asked Questions
Do I absolutely have to provide my VIN?
Yes. Providing your Vehicle Identification Number (VIN) is mandatory. We cannot ship the module without it. The VIN is essential for us to load the correct, vehicle-specific software and updates, ensuring the BCM works perfectly with your truck or SUV’s options and systems.
Is this part difficult to install?
The physical installation is typically straightforward for a DIYer with moderate experience. The BCM is usually located under the driver’s side dashboard. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. Since we handle the complex programming, you’ve already bypassed the hardest part of the job.
What if my airbag light is on after I install it?
This can happen on some models. It means the new BCM needs to be synced with the airbag system’s SDM module. A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process that resolves the light.
Will this BCM fit my vehicle?
This module replaces a wide range of original GM part numbers and fits dozens of vehicles, including the Chevy Suburban, Tahoe, Express Van, GMC Yukon, Savana Van, Cadillac Escalade, and more. Please review the detailed fitment list on this page to confirm compatibility with your exact year, make, and model.
What does ‘no core charge’ mean?
A core charge is a deposit that is refunded when you return your old, failed part. We do not require a core charge for this module, which simplifies your purchase. You are free to keep or dispose of your original BCM without any penalty.
