Restore Your Truck’s Electrical Systems with a Hassle-Free Solution
Are you dealing with baffling electrical problems in your 2015 GMC Sierra or a similar GM vehicle? Flickering lights, unresponsive power windows, random warning chimes, or a key fob that works intermittently are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your reliable truck into a source of daily frustration. Dealerships often quote sky-high prices for a new module plus mandatory programming fees, leading to expensive and time-consuming repairs.
We offer a smarter, more efficient solution. This is a replacement BCM that comes fully programmed through our expert cloning service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—like VIN, key fob information, and optional features—to this replacement unit. The result? A true plug-and-play module that is ready for installation right out of the box, eliminating the need for expensive dealer tools or programming. Get your truck’s convenience and safety features working like new again without the dealership headache.
From the Diagnostic Bay: The Case of the Haunted Truck
A customer brought in his 2015 Sierra 1500 with a list of bizarre symptoms. The radio would switch off, the dome lights wouldn’t work, and the power locks had a mind of their own. He’d already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I saw a flood of U-codes (U0140, U0155, U0164), all pointing to a loss of communication with the BCM. These codes are a dead giveaway. Instead of a complex and costly rewiring job, we identified the internal failure in the BCM. A cloned module like this one had him back on the road in a day, with all systems stable, for a fraction of the dealer’s quoted cost.
Is Your Truck Showing These BCM Failure Symptoms?
A failing BCM can cause a wide range of issues. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Power windows, locks, or mirrors not working or behaving erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security system or horn activating randomly.
- ✔ Key fobs failing to lock or unlock the doors.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminating without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0151, or other U-codes.
- ✔ A vehicle that won’t start despite having a good battery and starter (due to security system immobilization).
Your Straightforward BCM Installation Guide
Installing your pre-programmed module is a direct process. While the BCM location can vary slightly, on most 2015 Sierra and Silverado models, it’s found under the steering column on the driver’s side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most trucks, you’ll need to remove the lower dash panel beneath the steering wheel to access the module.
- Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test All Functions: Start the vehicle and test all body functions: lights, wipers, windows, locks, radio, and key fobs to confirm the repair.
Important Post-Installation Information
Our cloning service handles the vast majority of programming needs. However, in some GM vehicles, additional system handshakes or ‘relearns’ may be required after installation:
- ✔ Airbag System Sync: If the airbag warning 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. This is only necessary if the light appears.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and traction control functionality.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Once we receive it, our technicians will clone its data to the replacement module and ship it back to you, typically within 1-2 business days. This makes the new part plug-and-play.
Do I need to send my keys or key fobs?
No. All the necessary key and security information is stored within your original BCM. By cloning this data, your existing keys and fobs will work seamlessly with the new module upon installation.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your original module after the cloning service is complete, though we handle its return shipping back to you along with your newly programmed part.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before ordering to discuss options. We can often still program a module with your vehicle’s VIN, but some features may require dealer activation.
Will this fix my specific problem?
This programmed BCM will resolve issues directly caused by a faulty module. It’s crucial to properly diagnose the problem first. If your issues are due to bad wiring, faulty sensors, or other components, replacing the BCM will not fix them.
