Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, a non-responsive HVAC system, or strange security alerts in your Cadillac Escalade, Chevy Silverado, or GMC Sierra, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This genuine GM BCM, part number 15926094 (interchangeable with 25844480 and others), is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Symptoms of a Failing Body Control Module
- ✔ Unpredictable power windows, door locks, or remote keyless entry.
- ✔ HVAC controls that work intermittently or not at all.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Malfunctioning interior or exterior lights (headlights, taillights, dome lights).
- ✔ Vehicle security system faults or unexpected engine stalling.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).
Why Choose a VIN-Programmed BCM?
This isn’t just a part; it’s a complete solution. We program the module with the latest GM software updates using your vehicle’s VIN before it ships. This critical step ensures all systems communicate correctly right out of the box, eliminating the need for an expensive trip to the dealership for programming. It’s built to strict OEM standards for reliability and longevity, backed by a one-year warranty.
Installation Guide for Your 2007-2011 Escalade BCM
Installation is straightforward for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect everything and you’re done. In most cases, the vehicle will start and run perfectly. However, please note the following post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. 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.

Frequently Asked Questions
What does ‘VIN Programmed’ mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This makes it ready for installation without needing any additional programming from a dealer, saving you time and money.
Is this a difficult part to install myself?
For most people with basic tools, the physical installation is easy and takes less than 30 minutes. The module is located under the dash. The only potential complexity is if your vehicle requires a post-install procedure like an airbag system sync, which needs a professional scan tool.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of the B1001 code. Replacing the module will likely resolve the root cause, but you will still need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the light after installation.
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 hassle or extra fees.
How do I know if this BCM fits my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs, including the Escalade, Silverado, Sierra, Tahoe, and Yukon. Please verify your part number against our interchange list or use the fitment checker on our site to confirm compatibility.
