Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your vehicle? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly goes off can be incredibly frustrating. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can cause widespread, unpredictable problems. This service provides a reliable, pre-programmed BCM, offering a direct path to resolving these issues without the high costs and scheduling headaches of a dealership visit.
This is a comprehensive programming service for your 2014-2017 Caprice BCM and a wide range of other GM vehicles. The process is simple: you purchase this service, send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to a fully tested replacement module. We then ship the ready-to-install BCM back to you. This cloning service ensures seamless integration, making the installation process as close to plug-and-play as possible.
A Technician’s Notebook: The Case of the Caprice PPV
I had a 2015 Caprice Police Pursuit Vehicle (PPV) in my bay that was a real head-scratcher. The complaint was intermittent no-start and random warning lights on the dash—sometimes the airbag light, other times the traction control. The battery and alternator checked out perfectly. A deep scan revealed a slew of U-codes (communication loss) pointing to the BCM. After confirming power and grounds were good, it was clear the BCM itself was failing internally. Instead of a costly new module and hours of programming, we used a cloned unit. The swap took less than 30 minutes, and every single electrical gremlin was gone. The car started every time, and the dash was clear. It’s a perfect example of how this service saves time and money for both shops and owners.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. A failing module often triggers communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
- ✔ Intermittent or non-functional power windows, locks, or mirrors
- ✔ Erratic interior or exterior lighting (flickering, staying on, or not working at all)
- ✔ Horn sounding unexpectedly or not working
- ✔ Vehicle security system malfunctions or false alarms
- ✔ Inaccurate gauge readings on the instrument cluster
- ✔ No-start or intermittent starting problems
- ✔ Warning lights for ABS, Airbags, or Traction Control appearing without a clear cause
A Straightforward Guide to Installation
Installing your programmed BCM is a manageable task for a DIYer with basic tools. The location can vary slightly, but it’s typically found in the driver’s side dash area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most listed models, including the Caprice, the BCM is located under the steering column or on the left-hand side of the dash/firewall. 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 Replacement: Mount your new, programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- Test and Verify: Start the vehicle and test all body functions—lights, windows, locks, horn, etc.—to ensure everything is working correctly.
Important Post-Installation Notes
While our programming service handles the critical data transfer, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.
- No Core Charge: You are not required to return your old module. There is no core charge or deposit associated with this purchase.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician for procedures specific to your vehicle.

Frequently Asked Questions
What exactly is a BCM cloning service?
This service involves transferring the unique, vehicle-specific programming from your original BCM to a replacement unit. This ensures the new module works seamlessly with your vehicle’s existing keys, security system, and options, eliminating the need for expensive dealership programming.
Is this process difficult? What do I need to do?
The process is designed to be simple for you. After you place your order, we will contact you with clear instructions on how to ship your original BCM to our facility. Once we receive it, our technicians will perform the programming and ship the ready-to-install replacement back to you promptly.
Will this fix my car’s specific electrical problem?
If your vehicle’s issues match the common symptoms of BCM failure (erratic lights, window/lock problems, communication codes), this is a very likely solution. A proper diagnosis is always recommended, but a faulty BCM is the root cause of these types of widespread electrical issues.
Do I need any special tools to install the new BCM?
Typically, only basic hand tools like a socket set and a trim removal tool are needed to access and replace the BCM. Our programming service eliminates the need for advanced diagnostic scan tools for the initial setup. However, a scan tool may be required for post-install procedures like an airbag sync if the light is on.
What happens if I don’t get my original module programmed?
Installing a BCM from another vehicle without programming it to your car will not work. The vehicle will likely not start, and many electronic features will be inoperative because the module’s data won’t match your car’s VIN, security system, or specific options.
