Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with a frustrating array of electrical issues in your vehicle? Power windows that won’t roll down, door locks with a mind of their own, flickering interior lights, or random warning messages 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 command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of confusing and unpredictable problems. Don’t let a faulty module compromise your vehicle’s functionality and safety. This listing is for a professionally programmed BCM, providing a reliable and straightforward solution to restore your vehicle’s electrical systems to perfect working order.
From the Diagnostic Bay
We had a 2015 Silverado 2500 come into the shop that was driving the owner crazy. The radio would randomly shut off, the dome light would stay on, and the power locks would only work intermittently. He had already replaced the battery and checked all the fuses. A scan tool showed multiple ‘Loss of Communication’ codes with various modules. We suspected the BCM was the culprit. Instead of a costly new module and programming at the dealer, we performed a cloning service just like this one. We transferred the data from his failing BCM to a replacement unit. After a 15-minute install, every single issue was gone. It’s a perfect example of how a single failing module can create a host of seemingly unrelated problems.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, mirrors, and door locks.
- ✔ Erratic behavior of interior and exterior lighting (flickering, staying on, or not turning on).
- ✔ Malfunctioning security system or keyless entry.
- ✔ False warning lights on the instrument cluster (e.g., airbag, ABS, or check engine lights).
- ✔ Radio or infotainment system randomly shutting off or not working.
- ✔ Communication errors between various electronic modules (U-codes).
- ✔ Issues with the heating and air conditioning controls.
The Simple, Plug-and-Play Solution: Our BCM Programming Service
Replacing a BCM isn’t as simple as swapping the part. Modern BCMs are VIN-locked to the vehicle they were originally installed in. Simply installing a used module from another vehicle will not work and can cause even more issues. The dealership solution involves purchasing a brand-new module and paying for expensive programming. Our service bypasses this complexity and cost. We take the vital configuration and security data from your original, failing BCM and transfer it directly to this replacement unit. The result is a true plug-and-play module that is ready for immediate installation, with no additional programming required.
How Our Service Works:
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ Ship Us Your Original BCM: We will contact you with clear, simple instructions for shipping your original module to our facility. Please ensure your contact information is up to date.
- ✔ We Program Your Replacement: Upon receiving your module, our expert technicians will meticulously transfer all necessary data to the replacement BCM.
- ✔ Receive Your Ready-to-Install Part: We ship the programmed BCM back to you, typically within 1-2 business days of receiving your original. You’ll receive tracking information as soon as it’s on its way.
Installation and Post-Install Procedures for your 2015 Sierra Denali BCM
Installation is straightforward. The BCM is typically located under the driver’s side steering column or on the left-hand firewall. Disconnect the negative battery terminal before you begin. Carefully unplug the electrical connectors, unbolt the old module, and install the new one in its place. Reconnect the connectors and the battery terminal.
In some cases, minor post-installation procedures may be necessary:
- 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 airbag system with the new BCM. This is only required if the light is on.
- Brake Pedal Position Relearn: Depending on your specific model, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains the unique vehicle identification number (VIN), security information, and option configurations for your specific truck. By cloning this data to the replacement module, we create a true plug-and-play part, saving you from expensive and complex dealership programming.
Is this BCM new or used?
This is a high-quality, fully tested, and guaranteed good used BCM that has been programmed with your vehicle’s specific data. This provides a reliable and cost-effective solution.
What happens if I just install a used BCM from a junkyard?
A non-programmed BCM from another vehicle will not work correctly. It will have a different VIN and configuration, leading to a no-start condition, incorrect feature operation, and active security system issues. Our cloning service prevents all of these problems.
How long does the programming service take?
Once we receive your original module, the programming and testing process is typically completed within 1-2 business days. We then ship the ready-to-install replacement back to you.
What if the airbag light is on after I install the BCM?
This can happen occasionally. It simply means the airbag system needs to be electronically re-synced with the BCM. A qualified mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge?
No, there is no core charge. However, we do require your original module to be sent in to perform the data cloning service. You will not get your original module back.
