Restore Full Electrical Function to Your Cadillac
Is your 2010 Cadillac Escalade ESV suffering from bizarre and frustrating electrical problems? Issues like malfunctioning power windows, flickering lights, a faulty security system, or random warning messages on your dash are classic signs of 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 cause a wide range of disruptive symptoms. This replacement Body Control Module, part number 20864767, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2010 Escalade ESV in the shop that was driving its owner crazy. The radio would change stations on its own, the interior lights would stay on after the doors were closed, and the anti-theft system would occasionally prevent the truck from starting. After hours of chasing wires, we traced all the seemingly unrelated issues back to a single point of failure: the BCM. Once we installed a VIN-programmed module like this one, every single electrical gremlin vanished. It’s a powerful reminder of how critical this single component is to the vehicle’s entire operation.
Common Symptoms of a Failing BCM
- ✔ Erratic power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ Interior dome lights, headlights, or taillights failing to turn on or off correctly.
- ✔ The vehicle’s security system engaging randomly, causing a no-start condition.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service Airbag,” “Service StabiliTrak”).
- ✔ HVAC (heating and air conditioning) controls not responding properly.
- ✔ Inconsistent or non-functional remote keyless entry.

You receive a part that is ready for installation, eliminating the need for expensive scan tools or a trip to the dealer for programming.
Post-Installation Information
While this module is a direct-fit, plug-and-play solution, some GM vehicles may require minor post-installation procedures to ensure all systems are synchronized. These are simple steps that can often be performed with a capable diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is necessary to sync the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure proper operation of the brake lights and traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN after you place your order, and we will flash the module with the correct software for your 2010 Escalade ESV. It will arrive ready to install.
How do I provide my VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot ship your part until we have the VIN to program it correctly.
What if the airbag light comes on after I install the new BCM?
This is a known possibility on some GM vehicles. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure to resolve the light.
Is this a difficult part to replace?
On most compatible vehicles, including the Escalade, the BCM is located under the driver’s side of the dashboard. It typically involves removing a few trim panels for access. While the physical replacement is straightforward for someone with basic mechanical skills, we always recommend installation by a qualified technician.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
