Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a dead instrument cluster, or random warning lights, a failing Body Control Module (BCM) is likely the culprit. The BCM is the central nervous system for your vehicle’s electronic accessories, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This is a common problem in many 2015 GM models, including the Cadillac XTS, Chevy Silverado, and GMC Sierra. Instead of paying for expensive diagnostics and programming at a dealership, our mail-in programming service provides a simple, cost-effective, and reliable solution.

We make restoring your vehicle’s functionality straightforward. 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, retaining all your vehicle’s specific settings, key fob information, and security data. The result is a true plug-and-play module that requires no additional programming upon installation.

From the Diagnostic Bay
We recently had a 2015 GMC Sierra 1500 in the shop with a classic case of BCM failure. The owner was frustrated with intermittent no-starts, power locks that worked one minute and not the next, and a constant battery drain that left him stranded twice. After confirming the BCM was the source of the parasitic draw, we used our cloning service. By transferring his original data to a replacement unit, we had him back on the road the next day. No costly trip to the dealer, no reprogramming keys—just a simple, effective fix that restored the truck’s reliability.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system acting up, or the vehicle not recognizing your key fob.
- ✔ Unexplained battery drain that kills your battery overnight.
- ✔ Malfunctioning radio, climate controls, or other interior accessories.
- ✔ False warning lights on the dashboard, such as for the airbag or ABS system.
- ✔ Inability to start the vehicle, even with a good battery and starter.

Post-Installation Information
In most cases, this module is 100% plug-and-play. However, due to the complex nature of modern vehicle systems, some models may require a simple relearn procedure after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: On some vehicles, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Please consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of the electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Why is this cloning service better than buying a used BCM?
A standard used BCM from a junkyard is programmed to another vehicle’s VIN and options. It will not work in your car without expensive dealership programming. Our service clones your car’s exact data, making the replacement plug-and-play and saving you hundreds in dealer fees.
How long does the programming service take?
We typically program and ship your replacement module within 24-48 business hours of receiving your original BCM at our facility.
Do I need to send my keys with the module?
No. Because we are cloning all the data from your original BCM, the replacement will recognize your existing keys automatically. You do not need to send your keys.
Is this a guaranteed fix for my vehicle’s electrical problems?
This service will fix all problems directly caused by a faulty BCM. However, it’s crucial to ensure the BCM has been correctly diagnosed as the source of the issue. This service does not fix problems related to wiring, sensors, or other modules.
