Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. In my 20+ years as a technician, I’ve seen how these problems can escalate from a minor annoyance to a no-start condition. This professionally programmed 2012–2013 GM BCM is the definitive, reliable fix that gets you back on the road without the exorbitant costs and scheduling headaches of a dealership visit.
Our unique cloning service makes this repair straightforward for both DIY enthusiasts and professional shops. Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. Our experts will then transfer your vehicle’s exact configuration, key data, and security information to this replacement unit. The module you receive back will be 100% plug-and-play, tailored specifically to your vehicle’s VIN. This process preserves all original functionality and eliminates the need for expensive factory scan tools for programming.
A Technician’s Notebook: The 2012 Equinox That Baffled a Shop
A customer brought in a 2012 Chevy Equinox with a laundry list of complaints: the radio would turn off randomly, the dome light wouldn’t work, and occasionally the turn signals would stop flashing. Another shop had already replaced the battery and checked the alternator, but the issues persisted. After connecting my diagnostic tool, I saw multiple U-codes (communication errors) pointing to the BCM. Instead of a costly new module and hours of programming, we used a cloned BCM. The customer sent us their original module, we transferred the data, and sent the new one back. The installation took the customer less than 30 minutes in their driveway, and every single electrical gremlin was gone. It’s a testament to how effective this service is.
Is Your GM Showing These Telltale BCM Failure Signs?
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ The anti-theft or security light stays on, preventing the engine from starting.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) behave erratically.
- ✔ The horn honks unexpectedly or doesn’t work when pressed.
- ✔ Your key fob is no longer recognized by the vehicle.
- ✔ Multiple warning lights appear on the dashboard without a clear cause.
- ✔ Diagnostic scans show communication error codes (U-codes) like U0140.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to allow all systems to power down completely.
- ✔ Locate the BCM: The BCM’s location varies by model. Common spots include behind the driver’s or passenger’s side kick panel, under the dash, or in the engine compartment. Refer to a service manual for your specific vehicle if you’re unsure.
- ✔ Disconnect and Remove: Carefully unplug all 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 2012–2013 GM BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: lights, locks, windows, radio, etc., to confirm the repair was successful.
Important Post-Installation Information
While this module is programmed to be a direct fit, some GM vehicles require a simple handshake procedure between modules after installation. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems can be complex. Always consult a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is this cloning service?
Our cloning service is a process where we transfer the complete software and vehicle-specific data—including VIN, mileage, and key information—from your original BCM to this replacement unit. This makes the new module a perfect electronic match for your car.
Do I need to take my car to the dealer for programming after installation?
No. Because we clone your original data, this 2012–2013 GM BCM arrives ready for installation. No further programming or initialization by a dealer is required, saving you significant time and money.
What if the airbag light comes on after I install it?
This can happen on some models. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
