Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet, GMC, Cadillac, or Buick experiencing bizarre electrical issues? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or random warning lights on your dash are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. Instead of facing a costly trip to the dealership for a new module and expensive programming, we offer a streamlined, cost-effective solution.
From the Diagnostic Bay
We had a 2015 Silverado 1500 in the shop that was driving its owner crazy. The dome lights would randomly turn on while driving, the radio would shut off, and the power locks would cycle on their own. The customer had already replaced the battery to no avail. Our initial scan showed multiple communication errors between modules—a tell-tale sign pointing towards the BCM. Instead of a complex and expensive replacement requiring dealer-level tools, we opted for a cloned GM Body Control Module. We had the customer ship us his original unit, we performed a full data transfer to this replacement module, and shipped it back. The installation was a simple plug-in, and instantly, all the vehicle’s electrical gremlins were gone. It’s a perfect example of how the right part and service can save hundreds of dollars and hours of diagnostic headaches.
Why Choose Our Pre-Programmed BCM Service?
This listing is for a replacement BCM that is professionally programmed using the data from your original module. This cloning service makes the replacement process as simple as possible. You send us your original BCM, and our technicians will extract the vehicle-specific software, key data, and configuration settings. We then flash this exact data onto the replacement unit. The result is a true plug-and-play module that is ready for installation right out of the box, with no additional programming required. This process ensures that your vehicle retains all its original features and security information without any conflicts.
Common Symptoms of a Failing GM Body Control Module
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights, headlights, or taillights flickering, staying on, or not working.
- ✔ The horn honking randomly or failing to work when needed.
- ✔ Vehicle security system engaging incorrectly, causing no-start conditions.
- ✔ False warning lights (like the airbag or brake light) appearing on the instrument cluster.
- ✔ Inability for diagnostic scan tools to communicate with the BCM or other modules.
- ✔ Erratic behavior from the radio or climate control systems.
Important Post-Installation Procedures
While our goal is a seamless installation, some vehicle systems may require a simple recalibration after the new BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light illuminates after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary. This requires a professional-grade diagnostic tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights function correctly and the traction control system operates as intended.
Disclaimer: Specific relearn procedures can vary by vehicle model and trim. Always consult a factory service manual or a qualified automotive technician for guidance.

Frequently Asked Questions
How does this programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the necessary data to the replacement module and ship it back to you, typically within 1-2 business days.
Do I need to get this BCM programmed by a dealer after I receive it?
No. The module you receive will be fully programmed with your vehicle’s original data. This is a plug-and-play solution that does not require any additional dealer programming, saving you time and money.
What happens if my airbag light comes on after installation?
In some cases, the airbag system needs to be re-synced with the BCM. This is a standard procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a qualified technician with a professional scan tool.
Is this a difficult part to replace?
The location of the BCM varies by model (e.g., under the steering column, on the firewall), but replacement is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, removing trim panels, and swapping the module.
What part numbers does this BCM replace?
This module is a direct replacement for part numbers 13592137, 13506935, 13506936, 13587704, and 13594764. Please ensure your original module has one of these numbers.
