Is Your Vehicle Plagued by Baffling Electrical Problems?
Are you dealing with flickering lights, a radio that has a mind of its own, power windows that refuse to work, or a persistent ‘Service Vehicle’ message on your dash? These aren’t just minor annoyances; they are classic symptoms of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your interior lights and security system to your power locks and climate control. When it starts to fail, it can create a cascade of frustrating and unpredictable issues.
Replacing a BCM has traditionally been a costly and inconvenient process, requiring a trip to the dealership for expensive hardware and even more expensive programming. Our unique mail-in programming service eliminates that hassle entirely. We provide a simple, effective, and affordable solution to get your vehicle back to perfect working order without ever leaving your driveway for a dealership appointment.
The Simple, Plug-and-Play Solution: Our Mail-In Programming Service
Here’s how our streamlined service works: After you place your order, we will contact you with clear, step-by-step instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will transfer all the critical data—including your vehicle’s specific VIN, security information, and option programming—to a replacement unit. This ‘cloning’ process ensures the replacement module is a perfect digital match for your car. We then ship the fully programmed, plug-and-play BCM back to you. Installation is as simple as removing the old module and plugging in the new one. No dealership visits, no additional programming, no hidden fees.
From the Diagnostic Bay
We recently had a customer with a 2015 GMC Sierra whose truck was going haywire. The dome lights would stay on, draining the battery overnight, and the power door locks worked intermittently. He had already replaced the battery twice, assuming that was the issue. After a quick diagnostic, we suspected the BCM. Instead of a costly dealer replacement, he used our mail-in service. We cloned his original module, sent him the replacement, and he installed it in under 30 minutes. All the strange electrical gremlins vanished instantly. It’s a perfect example of how a failing BCM can mimic other problems, and how the right solution can save hundreds of dollars and significant frustration.
Common Symptoms of a Failing 2015-2016 CTS BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from the radio, climate control, or interior lighting.
- ✔ The security system alarming unexpectedly or preventing the vehicle from starting.
- ✔ False warning lights or messages appearing on the instrument cluster.
- ✔ A parasitic battery drain that kills your battery overnight.
- ✔ Complete loss of communication with various electronic modules.
Installation and Post-Install Considerations
Installing your newly programmed BCM is straightforward. Simply disconnect the negative battery terminal, locate your old BCM (locations vary by model, see fitment list), and swap it with the one we provide. Once installed and the battery is reconnected, your vehicle’s functions should be fully restored. However, in some GM vehicles, additional steps may be required:
- 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 a security measure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does ‘cloning’ or ‘programming’ mean for a BCM?
It means we transfer all the essential data from your original BCM—like the VIN, mileage, key fob information, and specific vehicle options—to the replacement unit. This makes the new module a perfect digital copy, allowing it to work in your vehicle without any additional programming from a dealer.
Is this BCM truly plug-and-play?
Yes, in over 95% of cases. Because we clone your original data, the installation is typically as simple as swapping the modules. In rare instances, as noted above, a security or sensor relearn procedure may be needed, which can be performed by a qualified mechanic with a professional scan tool.
How long does the mail-in service take?
We pride ourselves on a fast turnaround. Once we receive your original BCM, the programming process is typically completed and shipped back out within 1-2 business days. We will provide you with a return tracking number as soon as it ships.
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. If your module is severely damaged (e.g., by water or fire), please contact us before ordering to discuss options. We may be able to build a file for you using your VIN.
Do I need to return my old BCM after I receive the new one?
No, there is no core charge for this service. You are welcome to keep your original module. We only need it for the initial data transfer.
