Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2010 Cadillac Escalade? Intermittent power windows, flickering dash lights, a security system that acts up, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM falters, it can create a cascade of confusing and unpredictable problems. This isn’t just an annoyance; it’s a matter of reliability and safety. I’ve seen it countless times in my 20+ years in the bay—a perfectly good vehicle sidelined by a faulty BCM.
This is your direct, reliable solution. We offer a replacement Body Control Module, part number 20864768, that arrives at your door pre-programmed to your vehicle’s specific VIN. We load the latest, most stable software from GM, ensuring seamless integration and performance. You get a part that’s ready to install right out of the box, eliminating the need for an expensive trip to the dealership for programming. This is the same quality and reliability I’d install in a customer’s vehicle in my own shop.
A Technician’s Notebook: The Escalade with a Mind of Its Own
A few months back, a 2010 Escalade was towed in with a list of symptoms that sounded like a poltergeist was at work. The radio would switch stations on its own, the interior lights would pulse randomly, and the remote key fob worked only half the time. The owner was convinced the vehicle was possessed. After ruling out battery and alternator issues, my scan tool pointed to a communication breakdown with the BCM (DTC U0140). The internal logic was failing. Instead of a costly diagnostic rabbit hole, we installed a VIN-programmed BCM. In under an hour, every single ghost in the machine was gone. This is a classic BCM failure, and a quality, correctly programmed module is the definitive fix.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement is likely the solution:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or keyless entry system malfunctioning.
- ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, particularly U-codes like U0140, U0155, or U0164.
- ✔ Intermittent no-start or no-crank conditions where the battery is known to be good.
- ✔ Wipers or climate control operating incorrectly.
A Straightforward Guide to Your BCM Installation
For the confident DIYer or professional technician, swapping the BCM is a manageable job. While the exact location varies (check your service manual), the process is generally similar. Here’s a typical workflow for a 2010 Escalade Body Control Module replacement:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the 2010 Escalade, the BCM is typically found under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place of the old one. Securely reconnect all electrical connectors, ensuring they click into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Perform Post-Install Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. Note that some additional steps, or ‘relearns’, may be required.
Important Post-Installation Procedures
Because this module communicates with other key systems, you may need a professional scan tool to perform certain final synchronizations:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is a critical safety step.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
- No Core Charge: We make it simple. There’s no core charge, so you don’t have to worry about the cost or hassle of sending your old, faulty module back to us.

Frequently Asked Questions
Is this BCM really plug-and-play?
Yes, for most functions. We program it with the latest GM software using your VIN, so it’s ready for installation. However, as noted above, some vehicles may require a security, airbag, or brake sensor relearn procedure with a professional scan tool to sync all systems perfectly.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module without it, so please provide it promptly to avoid delays.
Will this fix my specific problem?
This module corrects faults originating within the BCM itself. While it resolves the most common electrical issues listed in the symptoms section, proper vehicle diagnosis is always recommended. This part will not fix issues caused by bad wiring, faulty sensors, or other failing modules.
What if I have an airbag light after installation?
An airbag light is a common occurrence after a BCM swap. It simply means the new BCM needs to be electronically ‘introduced’ to the vehicle’s SDM (Sensing and Diagnostic Module). A qualified technician with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
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 time and money.
