Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you chasing down bizarre electrical gremlins in your GM truck or SUV? Flickering lights, intermittent power windows, a security system that has a mind of its own, or worse—a vehicle that won’t start? As a technician with over two decades of diagnostic experience, I’ve seen these exact issues hundreds of times, and the culprit is often a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let a faulty module keep you off the road or drain your wallet with dealership diagnostic fees.
This is a complete, ready-to-install solution for your vehicle. We provide a fully functional replacement BCM that is professionally programmed with the data from your original module. This cloning service means you get a part that is truly plug-and-play. All the critical information—your vehicle’s VIN, security settings, and specific options—is transferred over. This eliminates the need for expensive and time-consuming programming with a dealership scan tool after installation. You simply send us your original BCM, we perform the service, and ship your ready-to-install replacement back to you promptly.
From the Diagnostic Bay: The Case of the Confused Silverado
A customer brought in his 2015 Silverado 2500 with a laundry list of complaints. The radio would randomly shut off, the dome light wouldn’t work, and the remote key fob was unresponsive. He’d already replaced the battery and checked all the fuses. A quick scan revealed a slew of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of just replacing the module and sending him to the dealer for a costly programming session, we identified the internal BCM failure. Using a service like this one, we were able to clone his original data to a replacement unit. The result? He was back on the road the next day with all issues resolved, no key relearn needed, and for a fraction of the dealership’s quote. This is the smart, efficient fix for these complex systems.
Is Your Truck Showing These BCM Failure Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- âś” Unresponsive power windows, door locks, or mirrors.
- âś” Interior or exterior lights not working correctly or staying on.
- âś” The security or anti-theft system preventing the engine from starting.
- âś” Inconsistent or non-functional remote keyless entry.
- âś” Warning lights on the dash, such as the airbag or service stabilitrak light.
- âś” Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0151, or other U-series codes.
- âś” Horn honking randomly or not working at all.
Your Straightforward BCM Swap Guide
Our cloning service makes the physical installation simple. Here’s a general guide for most compatible trucks and SUVs:
- 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 Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, often near the steering column or against the firewall.
- Remove Trim Panels: You may need to remove lower dash panels or kick plates to gain access. These are typically held in by clips or a few small screws.
- Disconnect and Remove: Carefully unplug the electrical connectors from the BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Package and Ship: Securely package your original BCM and ship it to us. We will contact you with detailed shipping instructions after your purchase.
- Install the Replacement: Once you receive the programmed module from us, simply reverse the steps. Mount the new BCM, plug in the connectors, re-install the trim panels, and reconnect the battery.
Important Post-Installation Information
While our service ensures your BCM is programmed correctly, certain vehicle systems may require a recalibration after the battery has been disconnected and the module replaced. Please be aware of the following potential procedures:
- âś” Airbag System Sync: If the 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 new BCM with the airbag system.
- âś” Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure proper brake light and traction control operation.
- âś” No Core Charge: You are not required to return your old part after the service is complete. Keep your original module.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Please check the original listing details for specific location and option requirements.
Why do I need to send my original BCM to you?
Your original BCM contains the unique VIN, mileage, security data, and programming for your vehicle’s specific options. By cloning this data to the replacement module, we create a true plug-and-play part, saving you from expensive dealership programming and key relearn procedures.
Will I need to get new keys made?
No. Because we transfer the security information from your original module, your existing keys will work exactly as they did before, with no additional programming required.
How long does the programming service take?
We typically program and ship the replacement module within 1-2 business days of receiving your original BCM. We’ll send you tracking information as soon as it’s on its way back to you.
What happens if my original BCM is completely dead or unreadable?
In the vast majority of cases, even with significant internal failure, we can still extract the necessary data. If for some reason your module’s data is completely corrupted and unrecoverable, we will contact you to discuss alternative options.
Is this a guaranteed fix for my vehicle’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are classic signs of BCM failure, proper vehicle diagnosis is always recommended. We guarantee our programming service and the functionality of the replacement module.
Do I need special tools for the installation?
For most vehicles, only basic hand tools are required to remove and replace the BCM (e.g., socket set, screwdriver, trim removal tool). No special electronic or programming tools are needed for the installation itself.
