Restore Full Electrical Function to Your GM Vehicle
Is your Silverado, Sierra, or other GM vehicle plagued by bizarre electrical problems? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a no-start condition can often be traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and difficult-to-diagnose issues. This listing offers a straightforward, reliable solution: a replacement BCM, part number 13594769, that is professionally programmed with your vehicle’s original data, making for a simple, plug-and-play installation.
The Brain of Your Vehicle’s Comfort and Security Systems
The BCM is a complex computer that manages a vast array of non-engine-related functions. It interprets inputs from switches (like your headlight switch or window controls) and sensors (like door ajar sensors) and sends commands to operate everything from your interior dome lights and power locks to your security system and climate controls. Because it’s so deeply integrated, a faulty BCM can manifest in seemingly unrelated ways, making diagnosis a challenge for even seasoned mechanics. Instead of spending hundreds on diagnostic fees and dealer programming, our service provides a direct path to a lasting repair.
From the Diagnostic Bay
We had a 2015 Sierra 2500 in the shop that was driving the owner crazy. The radio would randomly turn off, the driver’s side power window worked intermittently, and sometimes the truck wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The battery was new, and the alternator checked out fine. After checking the main power and ground connections, we suspected the BCM. Instead of a new, unprogrammed unit from the dealer which would require expensive programming, we used our cloning service. We transferred the data from the old, failing module to a good replacement unit. After a 15-minute install, every single electrical gremlin was gone. The truck started every time, and all accessories worked perfectly. It’s a prime example of how a failing 2015 Silverado Body Control Module can cause a host of confusing problems that a simple, pre-programmed part can solve.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, with gauges dropping out or warning lights flashing.
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ Malfunctioning remote keyless entry (RKE) or push-to-start systems.
- ✔ Security system issues, including false alarms or a ‘Service Theft Deterrent System’ message.
- ✔ A vehicle that cranks but refuses to start due to the BCM not recognizing the key.
- ✔ Unresponsive radio or climate control systems.
How Our Simple Mail-In Programming Service Works
Getting your truck back on the road is easy. This service eliminates the need for a trip to the dealership and the high cost of their programming equipment. The process is designed for your convenience:
- Place Your Order: Complete your purchase through our secure checkout.
- We Contact You: We will reach out to you using the contact information on your order to coordinate the next steps.
- Ship Us Your Original BCM: Carefully remove your original BCM and ship it to us. This module contains all the specific data for your vehicle’s options and security information.
- We Program the Replacement: Upon receiving your module, our technicians will transfer all the critical data from your original BCM to the replacement unit. This ‘cloning’ process ensures the new module is a perfect match for your vehicle.
- Receive Your Plug-and-Play Module: We ship the newly programmed BCM back to you, typically within 1-2 business days. Once you receive it, simply install it, and you’re ready to go. No further programming is required.
Post-Installation Procedures You Should Know
While our programming makes the installation process incredibly simple, some GM vehicles may require one or two minor recalibration procedures after the new 2015 Silverado Body Control Module is installed. These are standard procedures that can often be performed with a high-quality bidirectional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure the brake lights and traction control system function correctly.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that controls most of your vehicle’s electronic accessories and features that are not related to the engine. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster.
Why do I need to send my original module to you?
Your original BCM stores your vehicle’s unique VIN, security information (immobilizer data), and settings for all its specific options. By transferring this data to the replacement module, we make it a 100% plug-and-play part, saving you from a costly trip to the dealer for programming.
Is this BCM truly plug-and-play after your service?
Yes, in nearly all cases. Once we program the replacement module with your original data, you can simply install it and it will function immediately. Some vehicles may require minor relearn procedures, like for the airbag or brake pedal sensor, as noted in the description.
How long does the programming service take?
Once we receive your original BCM, our technicians typically complete the data transfer and programming within 24-48 hours. We then ship the programmed replacement module back to you promptly.
What if my original BCM is completely dead or unreadable?
In most cases, even if the BCM has failed, we can still extract the necessary data. If you believe your module is severely damaged (e.g., by water or fire), please contact us before ordering to discuss the situation.
