Restore Control and Reliability to Your GM Vehicle
Is your 2010 Cadillac Escalade ESV experiencing a host of bizarre electrical issues? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or an instrument cluster that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it falters, it can make driving frustrating and unpredictable. This replacement 2010 Escalade ESV Body Control Module, part number 20815898, is the definitive solution to restore your vehicle’s proper function and your peace of mind.
Our unique cloning service makes this repair easier than ever. Forget about costly towing fees and long waits at the dealership for programming. We transfer the essential data—including your VIN, key information, and vehicle-specific settings—from your original BCM directly onto this replacement unit. This means when you receive it, it’s truly plug-and-play. Your keys and remotes will work instantly, and you’ll avoid the complex and expensive programming procedures required for a new module from the dealer.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2010 Yukon XL (which uses this exact BCM) that came into my shop with a problem that had stumped two other mechanics. The owner complained of an intermittent no-start and a battery that would be dead every few days. We checked for a parasitic draw and found a significant one, but it was inconsistent. After hours of tracing circuits, we noticed the interior lights would faintly glow long after the truck was shut off. A scan tool showed intermittent communication loss with the BCM (Code U0140). The BCM wasn’t fully going to ‘sleep,’ causing the draw. We installed a cloned 2010 Escalade ESV Body Control Module, and the problem was solved instantly. It’s a perfect example of how a failing BCM can create phantom issues that seem unrelated.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry fails to operate correctly.
- ✔ Warning lights (like Airbag or ABS) appearing on the dash for no reason.
- ✔ Instrument cluster gauges behaving erratically or going dead.
- ✔ Communication error codes, such as U0140, U0155, or other ‘U’ codes.
- ✔ Unexplained battery drain leading to a dead battery overnight.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2010 Escalade ESV, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
- ✔ Disconnect Connectors: Carefully unplug all electrical connectors from the old BCM. The levers on the connectors must be fully released before pulling.
- ✔ Swap the Modules: Remove the mounting screws or clips holding the original BCM in place. Install the new module in the same location.
- ✔ Reconnect and Secure: Plug all electrical connectors firmly into the new BCM. You should hear or feel a click. Reconnect the vehicle’s battery.
- ✔ Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note the post-installation procedures below, as some relearns may be necessary.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the systems and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the complete software profile—including the VIN, mileage, security data, and options—from your original BCM to the replacement unit. This makes the installation plug-and-play, with no additional programming required.
Will my existing keys and remotes work after installation?
Yes. Because we clone your original module’s data, the replacement BCM will recognize your existing keys and remotes immediately upon installation.
Where is the BCM located on my 2010 Escalade ESV?
The Body Control Module is typically found under the driver’s side dashboard, attached to or near the steering column assembly.
What happens to my old BCM?
We always return your original module along with the programmed replacement unit. We do not keep your original part.
Why is the airbag light on after installing the new BCM?
The new BCM may need to be electronically introduced to the vehicle’s airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool to sync the modules and turn off the light.
