Is your 2010 Cadillac Escalade ESV experiencing bizarre electrical problems? Issues like flickering lights, unresponsive power windows and locks, or a security system that acts up are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose symptoms. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
This isn’t just a part in a box. We provide a comprehensive service by programming the module specifically to your vehicle’s VIN before it ships. This critical step ensures that the BCM communicates correctly with your Escalade’s other electronic systems, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest, delivering a part that is ready for installation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Instrument cluster warning lights appearing for no reason (e.g., ‘Service Theft System’).
- ✔ A persistent battery drain that kills the battery overnight.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The 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.
Is this part ready to install out of the box?
Yes! This BCM is programmed with the latest GM software using the VIN you provide. This ensures it is ready for installation, though some vehicles may require additional relearn procedures for systems like the airbags or brakes post-installation.
How do I know if my BCM is the problem?
Common signs are listed above, including random electrical issues with lights, locks, and windows, a ‘Service Theft System’ message, or a battery that repeatedly dies. A professional diagnosis is the best way to be certain.
Do I need to send my original BCM back?
No. There is no core charge for this part. You can keep your original module.
What if the airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be synced with the airbag’s computer (SDM). A ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional scan tool to resolve this.
Will this fit other vehicles besides the 2010 Escalade ESV?
Yes, this BCM is compatible with a wide range of GM vehicles. Please review the detailed fitment list on this page to confirm it matches your specific make, model, and year.
