Restore Order to Your Vehicle’s Electrical System
Is your GM truck, SUV, or sedan plagued by bizarre electrical gremlins? One minute the power windows work, the next they don’t. The radio might shut off randomly, or you’re facing a frustrating no-start condition with the security light flashing. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). The BCM is the nerve center for your vehicle’s body electronics, and when it fails, it creates chaos. This isn’t just an inconvenience—it can affect vehicle security and safety systems. Forget the dealership’s high costs and long wait times for programming. We offer a straightforward, reliable solution.
Our Simple, No-Hassle Programming Service
This listing is for a replacement BCM that arrives at your door fully programmed and ready for installation. The process is simple: after your purchase, we’ll provide instructions for you to ship your original BCM to our facility. Our expert technicians will then perform a full data transfer, essentially cloning all the critical vehicle-specific information—like key fob data, security settings, and option configurations—to this replacement module. We then ship the plug-and-play replacement back to you. This means no expensive scan tools or dealership intervention is required on your end. It’s the most efficient way to get a reliable fix.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in a 2015 Silverado 2500 with a list of complaints that sounded like the truck was possessed. The dome lights would flicker, the driver’s window would only work intermittently, and occasionally the truck would refuse to crank, showing a ‘Service Theft Deterrent System’ message. They had already replaced the battery and checked grounds. Initial scans showed a slew of U-codes, specifically U0140 (Lost Communication With Body Control Module). In my 20+ years of experience, a flood of communication codes pointing to one central module is a huge red flag. We isolated the BCM and confirmed it was failing internally. Instead of a costly new module and hours of programming, we used a cloned unit. The customer simply swapped the modules, and every single issue was resolved instantly. This is a textbook case where a failing BCM mimics multiple other problems, and our programming service provides the direct solution.
Signs Your Body Control Module is Failing
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights flicker or appear for no reason.
- ✔ The horn honks unexpectedly or doesn’t work at all.
- ✔ Key fobs stop working or work intermittently.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes.
- ✔ Wipers turning on by themselves or not responding to the switch.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the Sierra or Tahoe, the BCM is located under the driver’s side of the dashboard, often near the steering column. On sedans like the CTS or XTS, it may be in the dash or near a hinge pillar. Consult a service manual for the exact location on your vehicle.
- ✔ Remove the Old Module: Carefully unplug all electrical connectors. 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 new, pre-programmed BCM into the mounting bracket and secure it. Reconnect all electrical connectors firmly, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm everything is working correctly. Note the potential post-installation procedures below.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. Specifically, be aware of the following potential procedures:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light operation and to satisfy the traction control system.
- No Core Charge: You are not required to return your old module to us. This is a direct purchase with a programming service included.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we will contact you with a shipping address and instructions. You will need to send us your original Body Control Module. Once we receive it, our technicians will transfer all the vehicle-specific data to the replacement unit and ship it back to you, typically within 1-2 business days.
Is this really plug-and-play?
Yes, for over 95% of installations. Because we clone your original data, the replacement module is recognized by your vehicle’s other computers, eliminating the need for dealership programming. In rare cases, a simple relearn procedure like for the brake pedal sensor may be needed, as noted in our description.
Do I need to return my old BCM for a core charge?
No. There is no core charge for this item. You only need to send us your original module for the data cloning service. You can keep it afterward if you wish.
What happens if I install it and the airbag light comes on?
This is an expected possibility. It means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my specific electrical problem?
This module is the solution for issues directly caused by a failing BCM, such as the symptoms listed above (erratic lights, locks, security faults, etc.). It will not fix problems originating from other components, like a bad window motor or a faulty wiring harness. Proper diagnosis is key.
