Restore Full Functionality to Your GM Vehicle
Are you battling bizarre electrical issues in your Cadillac, Chevy, or GMC? Flickering lights, malfunctioning power windows and locks, a security system that acts on its own, or even a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. In my 20+ years of automotive diagnostics, I’ve seen how a bad BCM can make a perfectly good vehicle feel unreliable. This isn’t just an inconvenience; it’s a matter of safety and functionality.
This replacement Body Control Module, compatible with part number 20935349 and many others, is your direct-fit, reliable solution. Forget about expensive dealership visits and the hassle of programming. We offer a professional cloning service that makes this repair straightforward. Simply send us your original BCM, and we will transfer all the critical data—including your vehicle’s VIN, key information, and specific options—to this replacement unit. It arrives at your door ready for installation, loaded with the latest GM software updates for optimal performance.
A Technician’s Notebook: The Misleading Battery Drain
I once had a 2010 Escalade ESV in the bay with a classic ‘parasitic draw’ complaint. The owner had replaced the battery twice, convinced it was the problem. Every morning, it was dead. After checking all the usual suspects, my scan tool showed intermittent communication loss with the BCM (DTC U0140). The BCM wasn’t fully ‘going to sleep’ when the truck was off, causing a slow but steady drain. Installing a cloned BCM didn’t just fix the strange interior light behavior the customer had dismissed; it solved the battery drain for good. It’s a perfect example of how the 2010 Escalade ESV BCM is the true source of many electrical headaches.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- âś” Intermittent or non-working power windows, door locks, or mirrors.
- âś” Erratic interior or exterior lighting (flickering, staying on, or not turning on).
- âś” Instrument cluster gauges behaving abnormally or warning lights appearing without cause.
- âś” Vehicle security system faults or alarm sounding randomly.
- âś” Remote keyless entry (RKE) failure.
- âś” No-start or intermittent starting conditions.
- âś” Communication error codes, such as U0140, U0155, or B1001.
A Straightforward Guide to Your BCM Installation
Thanks to our cloning service, installing your replacement 2010 Escalade ESV BCM is a plug-and-play process. While the exact location varies by model (see fitment list), the general steps are consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: On most trucks and SUVs like the Escalade, Tahoe, and Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column. On sedans and vans, it may be in the dash or behind a kick panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reinstall any trim panels you removed, reconnect the battery terminal, and start the vehicle. Test all body functions to ensure proper operation.
Important Post-Installation Steps
In some cases, additional vehicle-specific relearn procedures may be required after installation. These are typically simple but essential for full system integration.
- Airbag System Sync: If your airbag warning light is illuminated 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: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Disclaimer: Always refer to a factory service manual for your specific vehicle for detailed instructions and torque specifications.

Frequently Asked Questions
Frequently Asked Questions
What is a ‘Cloning Service’ and how does it work?
Our cloning service is a simple and effective process. You send us your original BCM, and we use specialized equipment to extract its unique data (VIN, mileage, key codes, options). We then transfer this data to the replacement module. This makes the new BCM a perfect ‘clone’ of your original, eliminating the need for any dealership programming.
Do I need to program this module after I receive it?
No. Because we clone the data from your original unit, this BCM will arrive ready to install. It’s a true plug-and-play solution, designed to save you time and money.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this and turn off the light.
What is the process after I place my order?
After you purchase, we will provide you with shipping instructions to send your original BCM to us. Once we receive it, we will perform the cloning service and ship both your original module and the ready-to-install replacement back to you promptly.
Will this fix a no-start problem in my 2010 Escalade ESV BCM?
A failing BCM is a very common cause of no-start or intermittent start conditions in these vehicles, as it controls the anti-theft system. If your vehicle’s security light is on or flashing when it won’t start, a faulty BCM is a highly likely cause. This module will resolve that issue.
