Restore Your Vehicle’s Brain without the Headache
Are you chasing electrical gremlins in your GM vehicle? Flickering lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s comfort and convenience features. When it fails, it can make your daily drive a frustrating experience. In my 20+ years as a technician, I’ve seen how a faulty BCM can mimic a dozen other problems, leading to wasted time and money on incorrect diagnoses.
Forget the expensive trip to the dealership and the hassle of towing your vehicle for programming. We offer a simple, effective solution: a professionally programmed BCM ready for installation. Our service is designed to get you back on the road quickly and affordably. We transfer the vital data from your original module directly to this replacement unit, making it a true plug-and-play fix. This process ensures all your vehicle’s original features and security settings work perfectly, just as they did from the factory.
A Technician’s Notebook: The 2015 Silverado Ghost
A customer brought in a 2015 Silverado 1500 with a list of bizarre symptoms: the dome light would stay on, the radio would randomly shut off, and sometimes the truck just wouldn’t start. There were no check engine codes, just a few random communication (U-series) codes that would come and go. After checking the main power and ground connections, we suspected the BCM. Instead of a new, unprogrammed module from the dealer, the customer opted for our cloning service. We had them ship their original BCM to us. Once we cloned it to our replacement module and shipped it back, they installed it in under 30 minutes. Every single electrical issue was gone. No programming, no key relearn, just a simple, effective fix.
Is Your GM Vehicle Showing These BCM Failure Signs?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
- ✔ A dashboard that seems to have a life of its own, with gauges dropping out or warning lights flashing intermittently.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a ‘handshake’ with the new module. In some cases, you may need to perform a simple relearn procedure. This is not a sign of a defective part but a normal security and safety function of the vehicle’s network.
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the airbag system with the BCM and must be done with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
There is no core charge for this service. You can keep your old module. We stand by our work and are here to help you get your vehicle running right.
Frequently Asked Questions About the 2015-2016 GM BCM
Frequently Asked Questions
How does the cloning service work?
You purchase this item and then ship your original BCM to us. We use specialized equipment to read the unique software, VIN, and security information from your module and write it onto the replacement unit. This makes the new module an exact electronic copy of your old one, ensuring seamless integration with your vehicle.
Do I need to program this BCM or have my keys relearned?
No. Because we clone your original data, the replacement BCM is 100% plug-and-play. The vehicle will recognize it as the original, so no additional programming or key relearning is necessary, saving you hundreds of dollars in dealership fees.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is preventing the car from starting or communicating on the main network, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire.
How long does the entire process take?
We program and ship your replacement module the same business day we receive your original. The total turnaround time will depend on shipping speeds to and from our facility.
What tools do I need for installation?
For most models, you’ll only need basic hand tools like a socket set and a screwdriver to access and remove the BCM. No special electronic tools are required for the installation itself.
Why did my airbag light come on after installation?
This is a normal security measure on some GM vehicles. The BCM and the airbag module (SDM) need to be electronically re-synced. A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
