Is Your GM Vehicle Plagued by Electrical Gremlins?
Are you dealing with a frustrating array of electrical issues in your 2015 GMC Sierra, Silverado, or other compatible GM model? Flickering lights, malfunctioning power accessories, or a security system that seems to have a mind of its own are common indicators of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause widespread and unpredictable problems that are difficult to diagnose.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was driving the owner crazy. The radio would randomly shut off, the dome light would flicker, and occasionally the truck wouldn’t start, displaying a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked the alternator. After hooking up our diagnostic scanner, we saw multiple communication loss codes with various modules. Instead of a complex wiring issue, all signs pointed to a corrupted 2015 Sierra BCM. A new BCM from the dealer would have cost a fortune plus programming fees. Our cloning service provided a reliable, cost-effective solution that got the truck’s electronics working perfectly again.
Common Symptoms of a Failing BCM
- ✔ Unpredictable power windows, mirrors, or door locks that work intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, not turning on, or flickering.
- ✔ The horn sounding randomly or failing to work when needed.
- ✔ Keyless entry remote not functioning correctly.
- ✔ The anti-theft or security system preventing the vehicle from starting.
- ✔ Erratic or non-functional windshield wipers and washers.
- ✔ False warnings or error messages appearing on the instrument cluster display.
- ✔ Communication issues with other vehicle modules, leading to a variety of seemingly unrelated problems.
The Simple, No-Dealer Solution: Our BCM Programming Service
Forget about expensive dealership visits, towing fees, and the hassle of programming a new module from scratch. Our professional programming service is the most efficient way to solve your BCM problems. We take a quality replacement BCM and transfer the critical data—including the VIN, mileage, key information, and specific options—directly from your original module. The result is a true plug-and-play component that is ready for installation right out of the box.
How Our Service Works:
- ✔ Place Your Order: Purchase this service and ensure your contact information is up to date.
- ✔ We’ll Contact You: Our team will reach out with clear, simple instructions and a shipping address for you to send your original BCM to us.
- ✔ Send Us Your Module: Carefully package and ship your original BCM to our facility.
Important Steps After Installation
Because our service clones your original data, the installation is typically seamless. However, in some GM vehicles, certain security and safety systems may require a quick sync-up procedure after the new module is installed. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What is a BCM cloning service?
BCM cloning is a process where we extract the unique, vehicle-specific software and security data from your original Body Control Module and flash it onto a replacement module. This makes the replacement unit an exact digital copy of the original, allowing it to work in your vehicle without any additional dealership programming.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle is locked to that vehicle’s VIN and options. It will not work in your car or truck without being completely reprogrammed by a dealer, which is costly and often not possible. Our service provides a fully programmed, plug-and-play module from the start.
How long does the entire process take?
Once we receive your original BCM, our technicians typically complete the programming service within 1-2 business days. The total time will depend on the shipping times to and from our facility. We will send you tracking information as soon as your programmed module is on its way back to you.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. However, if your module is severely damaged (e.g., by fire or water) and the data is unrecoverable, we will contact you to discuss other options. Please contact us before purchasing if you suspect your module is unreadable.
Do I need any special tools to install the BCM?
Installation typically requires basic hand tools to access the BCM, which is often located under the steering column or behind a kick panel. The module itself is connected with electrical connectors. While the physical installation is straightforward, remember that post-install procedures like an airbag sync may require a professional scan tool.
