Restore Full Electrical Function to Your Cadillac
Are you battling frustrating electrical gremlins in your 2010 Cadillac Escalade EXT? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or a mysterious battery drain are often symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and inconvenient problems. This replacement Body Control Module is the definitive solution to restore your truck’s systems to perfect working order.
This isn’t just a generic part off the shelf. We provide a fully programmed BCM specific to your vehicle. Simply provide your VIN during checkout, and our technicians will flash the module with the latest GM factory software and calibrations for your exact Escalade EXT. This ensures a seamless installation process, eliminating the need for an expensive trip to the dealership for programming. Get your luxury truck back to functioning the way it was designed to.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or alarm randomly activating or failing to set.
- ✔ A persistent parasitic battery drain that leaves you with a dead battery.
- ✔ Inaccurate or non-functional instrument panel gauges.
- ✔ Key fob not being recognized or working intermittently.
- ✔ Warning lights appearing on the dash with no apparent cause.
From the Diagnostic Bay
We had a 2010 Escalade come into the shop with a classic “mystery problem.” The owner complained of a dead battery every two or three days. He’d already replaced the battery and the alternator, but the issue persisted. After running a parasitic draw test, we traced the power drain to the BCM. It wasn’t fully going to sleep when the truck was off, slowly draining the new battery. Swapping in a correctly programmed BCM didn’t just solve the battery issue; it also fixed his intermittently working passenger window he hadn’t even mentioned. It’s a perfect example of how a single faulty module can create multiple, seemingly unrelated headaches.
Your Solution: A Programmed 2010 Escalade EXT BCM
This module is the direct-fit, reliable repair for your vehicle. We handle the complex programming so you can focus on the installation. By matching the software to your VIN, we ensure all your vehicle’s original features and options are recognized and function correctly from the moment you plug it in. This part is compatible with a wide range of GM vehicles and supersedes numerous older part numbers, making it a versatile and dependable solution.
Installation and Post-Install Considerations
Once you receive your VIN-programmed BCM, installation is straightforward. However, in certain vehicles, additional synchronization procedures may be required to ensure all related systems communicate correctly. These are known as ‘relearn’ procedures and may include:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a recalibration of the brake pedal position sensor. This is crucial for the proper operation of your brake lights and traction control system.
Please note: Specific requirements can vary by vehicle. We always recommend consulting a factory service manual or a certified technician for guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do on my Escalade?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, keyless entry, and instrument panel warnings.
Do I need to program this BCM after I receive it?
No. This BCM comes fully programmed to your vehicle’s specific VIN. You must provide us with your VIN at the time of purchase so we can load the correct software and calibrations before shipping it to you. This makes the installation process much simpler.
How can I be sure my BCM is the problem?
While a professional diagnosis is always best, common signs of a failing BCM include multiple, unrelated electrical issues. If your power locks, windows, and lights are all acting erratically, or you have a battery drain you can’t trace, the BCM is a very likely culprit. Please review the symptom list on this page.
What else is required after I install the new module?
For most installations, the module is plug-and-play. However, as noted above, some vehicles may require additional relearn procedures for the airbag system or brake pedal position sensor, which would need to be performed with a compatible diagnostic scan tool.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
