Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows that have a mind of their own, a security system that won’t cooperate, or a dashboard that lights up with random warnings? These frustrating and seemingly unrelated issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause widespread chaos. Getting a replacement from the dealership can be a costly and time-consuming ordeal, involving towing, expensive parts, and labor-intensive programming. We offer a streamlined, cost-effective solution.
The Simple, Reliable Solution: Our BCM Programming Service
This listing is for a replacement BCM that is professionally programmed with the data from your vehicle’s original module. This cloning process ensures that the replacement unit is a perfect match for your truck’s specific configuration and security settings. The result is a true plug-and-play module that eliminates the need for any additional programming or calibration at a dealership. This service for the 2015 Sierra BCM and other compatible models is designed to get you back on the road quickly and affordably.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Malfunctioning windshield wipers or horn.
- ✔ Vehicle security system faults or key fob recognition issues.
- ✔ False warnings on the instrument cluster (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Problems with the radio, climate control, or other interior accessories.

Post-Installation Information
While our goal is a seamless installation, some modern vehicles require a final handshake between modules. Here are a few procedures that may be necessary after you install your new 2015 Sierra BCM:
Airbag System Sync
If the airbag warning light is illuminated after installation, a procedure called “Setup SDM Primary Key in BCM” must be performed. This requires a professional-grade diagnostic tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM), which will clear the light.
Brake Pedal Position Relearn
In some cases, the vehicle may require a brake pedal position sensor recalibration. This ensures the brake lights and traction control system function correctly with the new module. This procedure also typically requires a diagnostic scan tool.
Disclaimer: 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 manages many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and various other comfort and convenience features.
Why do I have to send you my original BCM?
Your original BCM contains unique data specific to your vehicle’s VIN, options, and security keys. By cloning this data to the replacement module, we create a plug-and-play part that will work seamlessly with your vehicle without requiring a trip to the dealer for expensive programming.
Is this part truly plug-and-play?
Yes, in over 95% of cases, the installation is completely plug-and-play. In rare instances, as mentioned above, a simple relearn procedure like an airbag sync or brake pedal position relearn may be needed, which can be performed by most automotive shops.
How long does the programming service take once you receive my module?
Our standard turnaround time is 1-2 business days from the time we receive your original BCM. We then ship both modules back to you, and you will receive a tracking number at that time.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data for the cloning process. If you believe your module is severely damaged (e.g., by water or fire), please contact us before ordering to discuss options.
