Is Your 2015 Sierra Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your truck’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster. When the BCM starts to fail, it can cause a cascade of confusing and frustrating symptoms that can be difficult to diagnose. If your truck is acting possessed, a faulty BCM is a likely culprit.
From the Diagnostic Bay
We had a 2015 Silverado in the shop that was driving the owner crazy. The dome lights would flicker randomly, the radio would shut off, and occasionally the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. After hours of checking wires and grounds, we isolated the issue to an internal failure in the BCM. Instead of a costly trip to the dealer for a new module and programming, we used our cloning service. We transferred the data from his old, failing BCM to a replacement unit. He plugged it in, and every single issue was resolved instantly. No programming, no extra fees, just a working truck.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing no-start conditions or random alarm activation.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ False warning messages appearing on the driver information center.
- ✔ Communication issues with other modules, leading to multiple diagnostic trouble codes (DTCs).
The Easiest Plug-and-Play Solution: Our Cloning Service
Don’t waste time and money at the dealership. Our professional cloning service makes this repair simple and straightforward. We take all the critical programming—including the VIN, mileage, and security information—from your original BCM and transfer it directly to this replacement unit. The result is a module that is 100% plug-and-play, ready to be installed in your vehicle without any additional programming required.
How The Process Works:

Post-Installation Information
While our goal is a seamless installation, some vehicle systems may require a simple sync procedure after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading the essential vehicle-specific data (like VIN, security keys, and option configuration) from your original BCM and writing it onto a replacement module. This makes the replacement module a perfect electronic match for your vehicle, eliminating the need for dealership programming.
Why is this better than just buying a used BCM?
A standard used BCM from another vehicle will not work in your truck because it contains the VIN and security data from the donor vehicle. This will cause a no-start condition and other system conflicts. Our cloning service makes the replacement BCM a true plug-and-play part for YOUR specific truck.
How long does the entire process take?
Once we receive your original module, our cloning service is typically completed within 1-2 business days. The total time will depend on shipping times to and from our facility.
What if my original BCM is not communicating or is completely dead?
In many cases, even if the BCM is failing, we can still extract the necessary data. Please contact us before ordering if your module is completely non-communicative, water-damaged, or fire-damaged so we can discuss the available options.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and that is what we transfer during the cloning process.
