Are you battling a cascade of strange electrical issues in your Cadillac Escalade, Chevrolet Silverado, or GMC Sierra? From flickering lights and unresponsive power windows to a malfunctioning security system, these problems often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can make your truck or SUV feel unreliable. This genuine OEM-quality module, part number 15284816, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a simple, plug-and-play installation.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ HVAC system blower motor or climate controls failing to respond.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Intermittent stalling, misfires, or no-start conditions tied to the vehicle’s security system.
- ✔ Windshield wipers or exterior lights behaving unpredictably.
- ✔ A variety of communication-related diagnostic trouble codes stored in the system.

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, and can be swapped out in minutes. However, please be aware of two potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Always consult a service manual for your specific vehicle if you are unsure. By purchasing this 2007-2011 Escalade BCM, you’re getting a reliable part that solves the problem correctly the first time.
Frequently Asked Questions
What does a Body Control Module do on my Escalade?
The BCM is a computer that controls non-engine-related functions in your vehicle. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Is this a plug-and-play part?
Yes! We pre-program the module to your vehicle’s VIN before shipping. This allows for a direct installation without requiring any additional programming from a dealership.
What should I do if the airbag light stays on after I install this?
If the airbag light is on, you will need to have a technician with a professional scan tool perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync process that pairs the new BCM with your vehicle’s existing airbag module.
