Restore Your Truck’s Electrical System with a Hassle-Free Solution
Are you chasing electrical gremlins in your truck? Flickering lights, malfunctioning power windows, a temperamental security system, or a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose issues. This isn’t just an inconvenience; it can leave you stranded. This is the reliable, straightforward fix for your 2015 Silverado 3500 BCM and many other GM vehicles.
We offer a unique mail-in cloning service that eliminates the most significant barrier to this repair: costly and complex dealership programming. Instead of towing your truck to a dealer and paying hundreds for programming, you simply send us your original BCM. We transfer all the critical data—including your vehicle’s specific settings and key information—to this replacement module. When you receive it back, it’s a true plug-and-play installation. No additional programming, no special tools, just a reliable solution that gets you back on the road fast.
Case Study: A Tricky Diagnosis
A customer brought in his 2015 Sierra 2500 with a bizarre set of symptoms. The radio would randomly shut off, the dome lights would flicker, and occasionally, the truck wouldn’t crank, just a single click. He’d already replaced the battery and alternator with no luck. After connecting my scan tool, I saw several ‘U’ codes, specifically U0140 (Lost Communication with Body Control Module). This pointed me away from the charging system and straight to the BCM. These communication codes are a classic sign that the BCM isn’t properly talking to other modules. By swapping in a cloned BCM, we resolved all the electrical issues in under an hour, saving the customer from further guesswork and expensive part swapping.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Diagnostic trouble codes (DTCs) such as U0140, U0155, or various ‘B’ codes (Body codes).
- ✔ Wipers or climate control functions acting up without reason.
A Straightforward Guide to Installation
Our cloning service makes the physical installation simple. Here’s a general guide for a 2015 Silverado 3500 BCM replacement (location may vary on other models):
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most GM trucks like the Silverado and Sierra, the BCM is located under the driver’s side of the dashboard, often near the steering column. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat your newly programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, windows, locks, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and stability control operation.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we will provide you with shipping instructions. You’ll send us your original BCM. Once we receive it, we transfer its programming to the replacement unit and ship it back to you, typically within one business day. This ensures it’s ready for installation right out of the box.
Do I need to get this BCM programmed by a dealer?
No. The entire purpose of our service is to handle the programming for you. By cloning the data from your original module, we eliminate the need for any additional programming or key relearning procedures, saving you time and money.
What if my original BCM is completely dead or missing?
In cases where the original module is non-communicative or lost, we may still be able to program the replacement using your vehicle’s VIN. Please contact us before ordering to discuss the specifics of your situation.
Is there a core charge for this part?
No, there is absolutely no core charge. We need your original module to perform the cloning service, but you are not required to return it for a refund.
Will this fix my no-start problem?
If your no-start issue is caused by the vehicle’s anti-theft system being triggered by a faulty BCM, then yes, this will resolve the problem. The cloned BCM will have the correct key information, allowing your vehicle to start and run properly.
