Restore Full Functionality to Your GM Vehicle
Is your 2010 Cadillac Escalade or another GM vehicle experiencing a baffling array of electrical problems? From power windows that won’t budge to interior lights that flicker like a scene from a horror movie, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it malfunctions, it can cause chaos, making your daily drive a frustrating experience. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a straightforward, reliable solution. This is a replacement Body Control Module, compatible with part number 15819552 and many others, that arrives at your door pre-programmed for your specific vehicle. Using the Vehicle Identification Number (VIN) you provide, we flash the module with the latest GM software updates. This means you get a component that is ready for installation, bypassing the costly and time-consuming trip to the dealership for programming. Get your vehicle back to performing the way it was designed to, with all electronic features operating seamlessly.
A Technician’s Notebook
I remember a 2010 Escalade that came into my bay with a classic case of BCM failure. The customer was frustrated because the vehicle would intermittently fail to start, the radio would cut out, and the power locks were working on their own schedule. They had already replaced the battery and checked the alternator. After hooking up my diagnostic scanner, I saw multiple ‘U’ codes, indicating a loss of communication between modules. This is a tell-tale sign. The BCM acts as a gateway, and when it fails, it disrupts the entire network. We installed a VIN-programmed BCM like this one, and within an hour, every single issue was resolved. It’s a fix that brings immense relief to vehicle owners by solving a dozen problems at once.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. As a technician with over 20 years of experience, I’ve seen it all. Here are the most common signs that your BCM may need replacement:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ The horn sounding unexpectedly or not working.
- ✔ Instrument panel warning lights (like the airbag or ABS light) staying on.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
- ✔ Intermittent no-start condition where the engine cranks but won’t fire up.
Your Straightforward BCM Installation Guide
Installing your new 2010 Escalade BCM is a manageable job for a confident DIYer or a quick task for any professional. The module is typically located under the driver’s side of the dashboard.
- 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 most GMT900 trucks and SUVs like the Escalade, the BCM is mounted to the left of the steering column, often behind a lower dash panel. You may need to remove a plastic trim panel for access.
- Disconnect and Remove: Carefully 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 your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test the functions: windows, locks, lights, etc.
- Perform Relearns if Needed: Start the vehicle. If any warning lights appear (like the airbag light), you may need to perform a post-installation procedure as outlined below.
Important Post-Installation Steps
While our programming handles the heavy lifting, some vehicle systems may require a quick sync-up after the new BCM is installed. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, 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 relearn may be required to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the programming service work?
It’s simple. After you complete your purchase, you provide us with your vehicle’s 17-digit VIN. Our technicians then use this information to load the correct GM software and vehicle-specific calibration files onto the BCM before shipping it to you.
Do I need to send my original BCM to you?
No. This is a cloning service performed on our replacement module. We program the unit we send you, and your original module is always returned to you along with the programmed replacement unit. We do not keep your original part.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills and common hand tools (like a socket set and trim removal tool), this is a very manageable installation. The main challenge is typically accessing the module under the dash. Our pre-programming service removes the most difficult step, which is the software configuration.
What is a 2010 Escalade BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages a wide range of electronic systems not related to the engine. This includes power windows, locks, seats, interior/exterior lighting, the security system, and more. It acts as a central hub for these functions.
What happens if my airbag light turns on after I install it?
This is an indication that the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be completed by a mechanic or a shop with a professional-grade bidirectional scan tool.
