Is Your GM Vehicle Acting Possessed? It Could Be The BCM.
If your 2015 Silverado, Sierra, or other compatible GM vehicle is plagued by a host of bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights, security system, and even communication with other vital modules. When it fails, it can create a cascade of frustrating and seemingly unrelated problems, making your vehicle unreliable and difficult to use.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The dome lights would stay on intermittently, the radio would shut off randomly, and the key fob would only work half the time. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing to a network failure. The root cause? A faulty 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 was back on the road the next day with all electrical functions restored, saving him hundreds of dollars and significant downtime.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system acting up, or the vehicle not starting due to an anti-theft error.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers operating on their own or not responding to the switch.
- ✔ Warning lights flashing on the dashboard with no apparent cause.
- ✔ Radio or infotainment system randomly turning off or on.
The Simple, No-Dealer-Visit Solution: Our BCM Cloning Service
Don’t let a faulty BCM sideline your vehicle. Dealerships will charge a premium for a new module and then add on several hours of labor for programming. Our service is designed to be the most straightforward and cost-effective solution available. We provide a replacement 2015 Silverado BCM that is programmed by cloning the data from your original unit. This process ensures a perfect match with your vehicle’s specific options and security information.
How it works is simple:
- Place your order for this service.
- We will contact you with instructions for shipping your original BCM to our facility.
- Once we receive your module, our technicians will expertly extract the data and transfer it to a fully tested replacement BCM.
- We ship the programmed, plug-and-play replacement module back to you, typically within 1-2 business days.
The result is a BCM that is ready for immediate installation with no additional programming required. You get to keep your original module, and there is no core charge involved.
Post-Installation Information
While our goal is a seamless plug-and-play experience, some GM vehicles may require minor post-installation procedures. 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 functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any installation steps.

Frequently Asked Questions
How does this programming service work?
After you place your order, you will ship your original BCM to us. We then transfer its unique data (for VIN, mileage, and options) to a replacement module. We then ship the programmed replacement back to you, ready to be installed without any further programming.
Why is cloning better than buying a used BCM from a junkyard?
A used BCM from another vehicle is locked to that vehicle’s VIN and security system. It will not work in your truck without being reprogrammed by a dealer, which is often expensive and complex. Our cloning service makes the replacement module a perfect electronic match for your vehicle.
Is this part truly plug-and-play?
Yes, in over 95% of cases, the module is completely plug-and-play. In rare instances, as noted above, a relearn procedure for the airbag system or brake pedal position sensor may be required, which can be done with a professional scan tool.
What if my original BCM is completely dead or not communicating?
Even if your BCM is non-communicative, we can often still extract the necessary data from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire.
How long does the entire process take?
Once we receive your original module, our service typically takes 1-2 business days. The total time will depend on the shipping speed you choose to send your module to us and for us to return it.
