Tired of Bizarre Electrical Problems in Your GM Truck?
As a technician with over two decades of experience, I’ve seen it all. Your truck’s lights are flickering, the power windows have a mind of their own, or the radio suddenly dies. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s comfort and convenience features. When it starts to fail, it can create a cascade of frustrating and unpredictable issues. This isn’t just an annoyance—it can affect vehicle security and safety systems.
We offer a straightforward and reliable solution. Instead of paying for expensive diagnostics and programming at a dealership, you can get a replacement BCM that is a perfect electronic match for your vehicle. Our service involves cloning the essential data from your original BCM onto this fully tested replacement unit. This ensures seamless compatibility with your truck’s specific options and security information, providing a dependable fix for your 2015 Sierra 2500 BCM issues.
Case Study: A Tricky Diagnosis
I remember a 2015 Silverado 2500 that came into the shop with a laundry list of complaints: intermittent no-start, dash lights flashing like a Christmas tree, and the driver’s power window only working when it wanted to. The owner had already replaced the battery and alternator. After hooking up the scan tool, I saw a dozen ‘U’ codes, indicating a massive communication breakdown between modules. The culprit? A failing BCM was corrupting the entire data network. By providing a cloned BCM, we restored all communications and functions in a single afternoon, saving the customer hundreds compared to the dealership quote. This is the exact fix we provide here.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry malfunctioning, or the alarm sounding randomly.
- ✔ Radio or infotainment system turning on and off by itself.
- ✔ Dash warning lights (like Airbag or ABS) illuminating for no reason.
- ✔ Communication Diagnostic Trouble Codes (DTCs), especially U-codes like U0140, U0155, or U0100.
- ✔ The vehicle failing to start due to anti-theft system errors.

Important Post-Installation Notes
While our cloning service makes this a near plug-and-play process, some GM vehicles may require a simple relearn procedure after installation. This is standard and can sometimes be necessary when modules are swapped.
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we’ll email you instructions for shipping your original BCM to us. We then copy its unique data to a replacement module and ship the ready-to-install replacement back to you. This process ensures 100% compatibility without needing a trip to the dealer.
Do I need to send my keys?
No, you do not need to send your keys. All the necessary security information is stored within your original BCM, and we transfer that directly. Your existing keys will work seamlessly with the new module.
Is there a core charge for my old BCM?
No, there is no core charge. We need your original module to perform the data cloning service, but you do not need to return it to us afterward unless you arrange for a separate disposal service.
Will this fix my specific problem?
This service is designed to fix problems caused by a faulty BCM. If your vehicle is showing symptoms from our list, there is a very high probability this will be the solution. A proper diagnosis is always the best first step to confirm the BCM is the root cause.
What is the turnaround time?
We typically program and ship your replacement BCM within one to two business days of receiving your original module. You will receive a tracking number as soon as it’s on its way back to you.
