Restore Full Electrical Function to Your GM Vehicle
Is your 2015 GMC Sierra, Silverado, or other GM vehicle plagued by bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This isn’t just an inconvenience; a faulty BCM can lead to a no-start condition, leaving you stranded. Don’t let a failing module dictate when and how your truck operates.
We offer a reliable and straightforward solution: a replacement BCM programmed specifically for your vehicle. This is not a generic, off-the-shelf part that requires expensive dealer programming. Instead, we utilize a professional cloning service. You simply send us your original BCM, and we transfer all its vital data—including the VIN, security information, and specific options—to this replacement unit. The result is a true plug-and-play module that restores your vehicle’s functionality without the need for a trip to the dealership.
Solving Your Electrical Issues with a Programmed 2015 Sierra BCM
The Body Control Module is a critical component that manages a vast array of non-engine-related functions. Its failure can manifest in numerous ways, often making diagnosis a challenge for the average DIYer. By choosing our pre-programmed module, you are getting a part that is ready to be installed right out of the box, saving you significant time, money, and hassle compared to dealership alternatives.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning security system or keyless entry.
- ✔ Warning lights appearing on the dashboard without a clear cause (e.g., ABS, Airbag, Traction Control).
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Radio or infotainment system acting strangely.
- ✔ Horn honking unexpectedly or not working at all.
Simple Process, Lasting Solution
Our process is designed for your convenience. After you place your order, we will contact you with clear instructions for shipping your original BCM to our facility. Once we receive it, our technicians will perform the data transfer to the replacement module, typically within 1-2 business days. We then ship the newly programmed module back to you, ready for installation. This service ensures that all your vehicle’s original settings and key programming are retained.
This module is a direct fit for the following part numbers: 13592137, 13506935, 13506936, 13587704, 13594764.
Post-Installation Procedures
While this is a plug-and-play solution, some GM vehicles may require minor recalibration procedures after the new BCM is installed. These are typically straightforward and can sometimes be required to ensure all systems communicate correctly.
- 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 syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures. There is no core charge for this part, so you can keep your original module.
Frequently Asked Questions
What is a BCM cloning service?
BCM cloning is a process where we extract the essential data (like VIN, mileage, key programming, and vehicle options) from your original module and write it onto the replacement module. This makes the new part an exact electronic copy of the old one, allowing it to work in your vehicle without any additional dealer programming.
Why can’t I just install a used BCM from another truck?
A used BCM is programmed to the VIN and security system of its original vehicle. Installing it in your truck will cause a mismatch, leading to a no-start condition and numerous system malfunctions. Our cloning service resolves this conflict.
How long does the programming service take?
Once we receive your original BCM, the cloning process is typically completed and the new module is shipped back out within 24-48 business hours. We will provide you with a return tracking number as soon as it ships.
What exactly do I need to ship to you?
You only need to ship us your original Body Control Module. After you place your order, we will provide you with detailed shipping instructions and the address for our facility. Please ensure your contact information is correct on your order.
Will this fix my specific electrical problem?
This part will correct issues caused by a faulty BCM. If you are experiencing any of the common symptoms listed, such as erratic lights, power lock/window failure, or security system faults, a failing BCM is the most likely cause. Proper diagnosis is always recommended.
What if the airbag light comes on after I install it?
This is a known possibility on some GM models. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
