Restore Full Electronic Control to Your 2010 Cadillac Escalade ESV
Are you battling frustrating and unpredictable electrical issues in your Cadillac? Flickering lights, malfunctioning power windows, erratic dashboard warnings, or features that work one minute and not the next are 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 make driving your luxury SUV a nerve-wracking experience. This replacement Body Control Module, part number 15880684, is the definitive solution to restore your vehicle’s functionality and your peace of mind.
Unlike a standard part from a dealership or local auto parts store, this BCM arrives at your door completely programmed and ready for installation. We take the hassle and high cost out of the equation. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures perfect communication between the BCM and all other modules in your Escalade, providing a seamless, plug-and-play repair.
From the Diagnostic Bay
We recently had a 2010 Escalade ESV in the shop with a laundry list of bizarre symptoms. The owner reported that the interior lights would stay on, the radio presets would randomly disappear, and the power liftgate would refuse to open. He had already replaced the battery and checked all the fuses with no success. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a costly and time-consuming dealer visit, we installed one of our VIN-programmed modules. After the quick installation and a simple brake pedal position relearn, every single issue was resolved. The vehicle’s electronics were stable and reliable again, saving the customer hundreds of dollars and significant downtime.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic or flickering interior and exterior lights.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ Malfunctioning climate control system.
- ✔ Key fob not working correctly or security system acting up.
- ✔ Radio or infotainment system behaving erratically.
- ✔ A vehicle that won’t start despite having a good battery and starter.
Understanding Your New 2010 Escalade ESV BCM Installation
This module is designed for a straightforward installation process. Because we handle all the programming beforehand, you eliminate the need for expensive dealer-specific scan tools. Once you install the module, some vehicles may require simple post-installation procedures to ensure all systems are synchronized. These are not complex repairs and can often be performed with common high-level diagnostic tools.
Post-Installation Procedures May Include:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This ensures the new BCM correctly communicates with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary. This is crucial for the proper function of your brake lights and the vehicle’s traction and stability control systems.
Please note: Specific requirements can vary by vehicle model and options. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Is this BCM truly plug-and-play?
Yes, for the vast majority of vehicles. We program it with your vehicle’s specific VIN and the latest GM software before shipping. This handles the most complex part of the replacement. Some vehicles may require minor, key-on relearn procedures or simple calibrations as detailed in the description, which can be performed with a capable scan tool.
Where do I find my VIN and how do I provide it?
Your 17-digit VIN can be found on your vehicle’s dashboard (visible through the driver’s side windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents. Please provide the VIN in the notes section during checkout or send it to us via email with your order number.
What if my original part number isn’t on the list?
The provided list covers a wide range of superseded and interchangeable part numbers. If your part number is not listed, please contact us with your VIN and original part number. We can verify compatibility to ensure you receive the correct module for your vehicle.
Do I need to return my old BCM?
No. We do not require you to return your original module. There is no core charge associated with this purchase, saving you the time and expense of shipping a core back.
Why is my airbag light on after installing the new BCM?
This is a normal security measure in GM vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade diagnostic tool to sync the components and turn off the light.
