Restore Full Electrical Function to Your GM Vehicle
Are you battling a storm of bizarre electrical problems in your 2015 GMC Sierra, Silverado, or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can make driving a frustrating and unpredictable experience. This isn’t just a part; it’s a comprehensive solution. We provide a replacement BCM, part number 13594764, that is professionally programmed with the exact data from your original module, ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come into the shop with the strangest symptoms. The radio would turn on and off, the dome lights would flicker while driving, and the driver’s side power window worked only intermittently. The owner had already tried replacing the battery and checking fuses with no luck. After connecting our diagnostic scanner, we saw multiple communication errors pointing directly to the BCM. He had bought a used BCM online and installed it himself, but that only made things worse—the truck wouldn’t even start because the security system didn’t recognize the keys. This is why our cloning service is so critical. By transferring the original data, we create a true plug-and-play module that works with your existing keys and vehicle configuration from the moment you install it, saving you from a costly trip to the dealer and the headache of a no-start situation.
Symptoms of a Failing 2015 Sierra Body Control Module
A faulty BCM can manifest in numerous ways, often seeming like multiple unrelated issues. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The vehicle’s security system or keyless entry fails to operate properly.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ False warnings on the dashboard, such as ‘Door Ajar’ or other system alerts.
- ✔ Communication issues with other modules, leading to various warning lights (ABS, Airbag, Check Engine).
- ✔ In severe cases, a no-start condition due to security system immobilization.

Post-Installation Procedures
While our cloning service makes this a plug-and-play repair, some GM vehicles may require minor recalibration procedures after the new module is connected. These are typically simple and can sometimes be required to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system with the new BCM and requires a professional-grade scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
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 cloning service?
Our cloning service involves transferring the complete software and vehicle-specific data (like VIN, mileage, and key information) from your original, failing BCM to a fully functional replacement unit. This makes the replacement module plug-and-play, avoiding the need for expensive dealer programming.
Why do I need to send you my original BCM?
Your original BCM contains the unique data that allows it to communicate with your vehicle’s other electronic modules and security system. By sending it to us, we can extract this critical information and ensure the replacement BCM is a perfect electronic match for your truck.
Is this solution truly plug-and-play?
Yes, in over 99% of cases. Because we clone your original data, the vehicle will recognize the replacement BCM as its own. In rare instances, a simple relearn procedure, like for the brake pedal position sensor, may be required, but you will avoid the complex and costly programming required for a new module.
Will my existing keys work?
Absolutely. The cloning process transfers all security information, including your key data. You will not need to have new keys made or programmed. Your current keys will work just as they did before.
How long does the entire process take?
Once we receive your original BCM, our technicians typically complete the cloning service within 1-2 business days. We then ship the replacement module back to you. Total turnaround time will depend on shipping speeds.
