Restore Full Functionality to Your GM Vehicle with a Programmed BCM
Are you dealing with baffling electrical issues in your 2010 Chevrolet Equinox? Flickering lights, malfunctioning power windows, a security system that acts up, or even a no-start condition can all point to a single culprit: a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect vehicle security and safety systems. This listing offers a straightforward, reliable solution to get your vehicle back to 100%.
We provide a professionally programmed BCM that is a direct replacement for part number 13504004 and others. The process is simple: after you place your order, you ship your original BCM to us. We then transfer all the critical vehicle-specific data—like key information and security settings—to this replacement module. This cloning service means that when you receive the BCM back, it’s ready for plug-and-play installation, eliminating the need for expensive and time-consuming programming at a dealership. We handle the complex part so you can focus on the simple installation.
A Technician’s Notebook: The Case of the Haunted Equinox
I remember a 2010 Equinox that came into my bay with a list of symptoms that seemed completely unrelated. The owner said the radio would turn on by itself, the dome lights wouldn’t turn off, and the remote key fob worked intermittently. A basic scan showed a dozen communication codes, primarily a U0140 (Lost Communication With Body Control Module). Instead of chasing each symptom individually, my experience pointed straight to the BCM. After installing one of our programmed modules, every single issue was resolved instantly. It’s a perfect example of how one central component can cause widespread electrical chaos.
Common Signs of a Failing BCM
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Unpredictable power windows, door locks, or interior/exterior lighting.
- ✔ The security or anti-theft system light is on, or the system engages randomly.
- ✔ The engine won’t crank or start, even with a good battery and starter.
- ✔ Dashboard warning lights illuminate for no apparent reason.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Horn, wipers, or other accessories working erratically or not at all.
A Straightforward Guide to Installation
Installing your new BCM is a manageable task for a DIYer or any professional mechanic. Our cloning service makes it a true plug-and-play process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the 2010 Equinox and similar models, the BCM is typically found on the left (driver’s) side of the dash or behind the kick panel.
- Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle to avoid damage.
- Swap the Modules: Unbolt or unclip the old BCM and remove it. Mount the new, programmed module in its place.
- Reconnect Everything: Plug all electrical connectors firmly into the new BCM. Reconnect the negative battery terminal.
- Test and Verify: Start the vehicle and test all functions: lights, windows, locks, wipers, and radio to confirm the repair.
Important Post-Installation Notes
In some cases, additional steps may be needed to sync all vehicle systems. This is normal for modern vehicles. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required 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 recalibration to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will provide instructions for you to ship your original BCM to us. We then extract the vehicle-specific data and flash it onto the replacement module. This ensures it works with your existing keys and settings, making it a plug-and-play installation for you.
Do I need to send my original BCM?
Yes, sending your original module is required for our cloning service. This is how we make the replacement part fully compatible with your vehicle without needing a trip to the dealer for programming.
How long does the process take?
We typically program and ship the replacement module within 24-48 hours of receiving your original BCM. We will send you a tracking number as soon as it’s on its way back to you.
Is this 2010 Equinox BCM difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The BCM is usually located behind the driver’s side lower dash or kick panel and is held in by a few bolts or clips. The main task is carefully swapping the electrical connectors.
What if my airbag light comes on after installation?
This is a possibility and requires a ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync procedure that can be performed by most professional repair shops with a capable diagnostic scan tool.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module after we have completed the cloning service.
