Is Your Truck’s Electrical System Acting Up?
If you’re dealing with bizarre electrical issues in your 2015 GM truck or SUV, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from power windows and locks to interior lighting and the security system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems, making your vehicle unreliable and difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system acting erratically, or a “Service Theft Deterrent System” message appearing on the dash.
- ✔ Windshield wipers activating on their own or not working when commanded.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Horn honking randomly or not working at all.
- ✔ Inaccurate or malfunctioning gauges on the instrument cluster.
The Simple, No-Dealer-Required Solution: A Programmed 2015 Sierra BCM
Simply swapping a used BCM from another vehicle won’t work. These modules are programmed with your specific vehicle’s Vehicle Identification Number (VIN) and security information. Our professional programming service eliminates the need for an expensive trip to the dealership. We provide a simple, cost-effective solution by transferring the critical data from your original BCM to a fully tested, replacement unit. This makes the new module a true plug-and-play component for your vehicle.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come into the shop with a classic BCM failure story. The owner complained that his radio wouldn’t turn off with the key out and the power locks would cycle randomly through the night, killing his battery. He’d already replaced the battery twice. A quick scan revealed a flood of communication errors all pointing back to the BCM. The dealership quoted him over $900 for a new module and the required programming. Our cloning service provided a reliable, plug-in solution that solved all the electrical gremlins and had him back on the road for a fraction of the cost.

Post-Installation Procedures
Our goal is a seamless plug-and-play experience. However, due to the complexity of modern vehicle systems, some models may require a simple relearn procedure after installation. Please be aware of the following possibilities:
- 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 syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How does this programming service work?
You purchase this service and send us your original, faulty BCM. We then extract the unique programming and security data from it and transfer it to a fully functional replacement BCM. We then ship both modules back to you.
Will this BCM be plug-and-play?
Yes, because we clone the data from your original module, the replacement BCM will be plug-and-play. It will work with your existing keys and vehicle settings, eliminating the need for dealership programming. In rare cases, a minor relearn procedure may be needed as described above.
Do I need to send my keys with my original BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which is what we transfer. Your existing keys will work seamlessly with the programmed replacement module.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data. If your module has severe water or fire damage, please contact us before ordering to discuss options.
