Are you tired of dealing with baffling electrical issues in your 2010 Chevrolet Equinox? One moment the power windows work, the next they don’t. The security light flashes for no reason, or your dashboard lights up with random warnings. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM), the electronic nerve center of your vehicle’s comfort and convenience features. A trip to the dealership can mean hundreds of dollars in diagnostic and programming fees, but there’s a smarter, more affordable solution.
This is a replacement BCM, part number 13578420, that arrives at your doorstep ready for installation. We eliminate the need for expensive dealer tools by offering a professional cloning service. Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. Our expert technicians will transfer all the critical data—like your vehicle’s VIN, key information, and specific options—to this replacement unit. We then ship the plug-and-play module back to you, ready to solve your electrical woes. It’s the most straightforward way to get your Equinox back to 100%.
From the Diagnostic Bay
I remember a 2010 Equinox that came into my shop with a laundry list of bizarre symptoms. The owner said the horn would randomly go off, the interior lights would stay on, and the remote key fob worked intermittently. He’d been to two other shops that couldn’t pinpoint the issue. My scan tool pulled a U0140 code—Lost Communication With Body Control Module. After verifying the wiring and power/ground circuits to the BCM were solid, I knew the module itself was the culprit. Instead of a costly new BCM and a day spent at the dealer for programming, we used a cloned module. The customer mailed in his old BCM, we transferred the data, and he installed the replacement himself in under an hour. The electrical gremlins vanished instantly. It’s a repair that saves time, money, and a massive headache.
Is Your Equinox Exhibiting These Electrical Gremlins?
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ The vehicle’s security system acting up, preventing the car from starting.
- ✔ Unpredictable behavior from the radio or climate control system.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as U0140, pointing to a communication failure with the BCM.
- ✔ The horn sounding without input or the panic alarm activating randomly.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- ✔ Locate the BCM: On the 2010 Equinox, the BCM is typically found on the left (driver’s) side of the dash, often behind the lower dash panel or kick panel.
- ✔ Remove Trim: 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 your new, pre-programmed BCM in the same location and reconnect all the electrical harnesses securely.
- ✔ Final Steps: Re-install the trim panels and reconnect the negative battery terminal. Start the vehicle to confirm the issues are resolved.
Important Post-Installation Information
While our cloning service makes this a true plug-and-play repair for most vehicles, some systems may require a ‘handshake’ after installation. Please be aware of the following:
- 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 airbag system with the new BCM. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure the brake lights and traction control system function correctly.
There is no core charge for this module. You can keep your original part. As always, specific procedures can vary, so consulting a factory service manual or a qualified technician for guidance is recommended.

Frequently Asked Questions
What exactly does the BCM do in my Equinox?
The Body Control Module is a computer that manages most of the non-engine related electronics in your vehicle. This includes power windows, locks, interior/exterior lights, the alarm system, and even the windshield wipers. When it fails, you see strange, unrelated electrical problems.
How does the mail-in cloning service work?
It’s simple. After you place your order, we’ll email you instructions and a shipping address. You mail us your original BCM. We then copy its unique programming and vehicle data to the replacement module and ship it back to you. This makes the new part plug-and-play.
Is this 2010 Equinox Body Control Module really plug-and-play?
Yes. Because we clone the data from your original module, the replacement BCM will have all the correct information for your specific vehicle, including VIN and security settings. This allows you to install it without any additional programming.
What if my airbag light comes on after I install it?
In some cases, the airbag system (SDM) needs to be re-synced with the BCM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be done with a professional-grade scan tool. It’s only required if the light appears after installation.
Do I have to send my original BCM back to you?
Yes, you must send us your original BCM so we can perform the cloning service. However, there is no core charge, and we do not keep your old module.
How long does the entire process take?
We typically clone and ship your replacement module within 1-2 business days of receiving your original BCM. The total time will depend on shipping speeds to and from our facility. We provide tracking information once it ships.
