Is Your Escalade Plagued by Electrical Gremlins?
As a technician with over two decades of experience under the hood, I’ve seen firsthand the chaos a failing Body Control Module (BCM) can cause. Your 2010 Cadillac Escalade ESV is a sophisticated machine, and the BCM is the central command for its body electronics. When it starts to fail, you’ll notice bizarre, frustrating issues that seem to have no rhyme or reason. One day the power locks work, the next they don’t. The dashboard lights up like a Christmas tree for no reason, or worse, the vehicle refuses to start. This isn’t just an annoyance; it’s a critical failure that compromises your vehicle’s reliability and safety.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We take the guesswork and extra expense out of the repair. Simply provide your vehicle’s VIN during checkout, and our experts will program this BCM with the latest GM software specific to your Escalade ESV. It arrives at your door ready for installation, allowing you to bypass a costly trip to the dealership for programming. This is the most direct way to restore full functionality to your vehicle’s essential systems.
Case Study: A Tricky Diagnosis
From the Diagnostic Bay
A customer brought in a 2010 Tahoe—which uses a similar BCM to the Escalade—with a complaint that was driving him crazy. The radio would turn off randomly, the interior lights would flicker, and occasionally the anti-theft system would engage, preventing it from starting. He’d already replaced the battery and checked the alternator. After connecting my scan tool, I saw a storm of U-codes (U0140, U0155, U0164), all indicating a loss of communication with the BCM. Instead of just throwing parts at it, we inspected the BCM’s connectors for corrosion, a common issue. They were clean. This confirmed the BCM itself had an internal failure. A new, pre-programmed BCM fixed every single issue in one go. This is a classic BCM failure scenario I’ve diagnosed hundreds of times.
Common Signs of a Failing GM BCM
If you’re experiencing any of these symptoms, a faulty BCM is the most likely cause. Don’t let these issues persist and potentially cause further damage to other electronic components.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic instrument cluster behavior (flickering gauges, warning lights).
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ “Service Stability System” or other warning messages appearing on the dash.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes.
- ✔ Complete failure to start with all other components (battery, starter) testing good.
A Straightforward Guide to Your BCM Installation
Installing your new 2010 Escalade ESV Body Control Module is a manageable job for a DIYer with basic tools. On the Escalade, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Access the Module: You may need to remove a lower dash panel or knee bolster to gain clear access to the BCM. These are usually held in by a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reinstall any panels you removed and reconnect the negative battery terminal. Start the vehicle and test all functions: lights, locks, windows, radio, etc.
Important Post-Installation Steps
Because this module is central to many systems, a couple of quick relearn procedures may be necessary after installation:
- Airbag System Sync: If your airbag warning light is on after the swap, 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control work as intended.
Please Note: There is NO CORE CHARGE for this part. You can keep your old module.

Frequently Asked Questions
Do I need to do anything after I order?
Yes. After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship your BCM without it.
Is this part really plug-and-play?
For most functions, yes. Because we program it to your VIN, it will control the basic body functions right away. However, as noted above, some vehicles may require a simple relearn procedure for the airbag system or brake pedal position sensor using a pro-level scan tool.
What if my original part number is not 15828601?
That’s okay. This BCM is a direct replacement for all the part numbers listed in the description. As long as your original number is on that list, this module will work for you.
Why is a programmed BCM better than a used one from a junkyard?
A used BCM from another vehicle is programmed with that vehicle’s options and VIN. It will not work correctly in your car and will require expensive dealer programming. Our BCMs are loaded with fresh software specific to your exact vehicle, ensuring proper function from the start.
Do I need to send my old BCM back?
No, there is no core charge on this item. You can keep your old part.
