Tired of Chasing Electrical Gremlins in Your GM Vehicle?
If you own a 2014-2017 SS Caprice or another compatible GM vehicle, you know how frustrating it is when things just stop working correctly. Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or a car that won’t start at all—these aren’t just annoyances; they’re signs that your vehicle’s central command center, the Body Control Module (BCM), may be failing. In my 20+ years of diagnostics, I’ve seen how a faulty BCM can create a cascade of baffling issues that seem unrelated, sending owners and even some technicians on a wild goose chase for a solution.
The BCM is the electronic brain that manages all the non-engine-related functions in your vehicle. It controls everything from your interior lights and power locks to your instrument cluster and security system. When it fails, the symptoms can be unpredictable and widespread. Replacing it used to mean an expensive trip to the dealership for a new module, plus hours of labor for programming. Our service eliminates that entire headache.
A Technician’s Notebook: The Silverado That Wouldn’t Behave
A 2015 Silverado 1500 came into the shop with a laundry list of complaints from the owner. The radio would randomly shut off, the dome light would stay on, and occasionally, the turn signals wouldn’t work. He had already replaced the battery and checked all the fuses. We scanned for codes and found a slew of U-codes (communication errors) pointing to a network issue. After checking the wiring harnesses and grounds, all signs pointed to an intermittent internal failure in the BCM. Instead of a costly new unit and programming, we used a cloned module. The customer sent us his original BCM, we transferred the data, and sent the replacement back. He installed it in under an hour, and every single electrical issue was resolved. It’s a perfect example of how this 2014-2017 SS Caprice BCM solution gets you back to normal without the dealership hassle.
Is Your Vehicle Showing These Telltale Signs?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ The security system acting up, preventing the car from starting (anti-theft light on).
- ✔ Instrument panel gauges behaving strangely or warning lights appearing for no reason.
- ✔ Communication error codes stored in the system (often U-codes like U0140).
- ✔ A vehicle that won’t start despite having a good battery and starter.
How Our Simple Cloning Service Works
This isn’t just a part; it’s a complete, ready-to-install solution. You purchase this listing, and we’ll contact you with simple instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will extract the unique vehicle-specific data—including key information and security settings—and flash it directly onto this replacement module. We then ship the fully programmed BCM back to you, typically within one business day. The result? A true plug-and-play fix. No dealer visit, no expensive programming tools, no hassle.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: On the 2014-2017 SS Caprice and many other GM models, the BCM is typically located under the driver’s side of the dashboard, near the steering column. A quick search for your specific model’s BCM location can be very helpful.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Seat the replacement BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a ‘click’ when they are properly seated.
- ✔ Reconnect the Battery: Re-attach the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and test all body functions (lights, windows, locks, etc.). In some cases, as noted below, a ‘relearn’ or ‘sync’ procedure may be needed for specific systems like the airbags or brake pedal sensor.
Important Notes on Post-Installation Procedures
While our programming handles the vast majority of functions, some vehicle safety systems may require a final handshake after installation. This is normal and part of the vehicle’s design.
- Airbag System Sync: If the airbag light is on after installation, a simple “Setup SDM Primary Key in BCM” procedure is required. This must be done with a bi-directional scan tool to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure brake lights and stability control function perfectly.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
Do I need to send my original BCM to you?
Yes. This is a cloning service. We need your original module to transfer its specific programming and security data to the replacement unit, ensuring it works seamlessly with your vehicle.
Is this BCM difficult to install?
No, the physical installation is straightforward for most DIYers with basic tools. It involves unplugging the old module and plugging in the new one. The main benefit is that our service removes the difficult programming step.
Will I need to go to the dealer after installation?
No! Our programming service is designed to eliminate the need for dealer intervention. The module arrives ready to be installed and function correctly. The only exception is the potential need for an airbag or brake sensor relearn, which can be done by most independent shops.
What is a core charge?
There is no core charge for this item. You can keep your original module after you receive the programmed replacement from us.
What happens after I purchase?
After you complete your purchase, we will contact you with clear, step-by-step instructions and the shipping address for you to send your original BCM to us. Please ensure your contact information is up to date.
How do I know if the BCM is really the problem?
Diagnosing a BCM requires checking for specific trouble codes (especially U-codes), verifying power and ground at the module, and ruling out other causes like bad wiring or fuses. The symptoms listed above are strong indicators of a failing 2014-2017 SS Caprice BCM.
