Are you chasing electrical gremlins in your 2014-2017 Chevrolet Caprice? One minute the power locks work, the next they don’t. Maybe the interior lights are flickering, or worse, the vehicle won’t start at all. These frustrating, intermittent issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s comfort and security features, and when it starts to go, it can cause a cascade of bizarre problems. Dealerships will quote you a fortune for a new module plus mandatory programming fees. We offer a smarter, more cost-effective solution.
This is a fully tested replacement BCM that we program specifically for your vehicle using the data from your original module. This cloning service makes the repair process simple. You send us your original BCM, we transfer all the critical vehicle-specific data (including key information and security settings) to this replacement unit, and ship it back to you ready for installation. The result is a true plug-and-play fix that restores full functionality without a trip to the dealer. It’s the most reliable way to solve your BCM issues and get your Caprice operating like new again.
A Technician’s Notebook: The Ghost in the Machine
I had a 2016 Caprice PPV come into the bay that was driving the owner crazy. The complaint was an intermittent no-start and the radio display going blank randomly. The battery tested perfectly, alternator was charging, and there were no obvious wiring issues. The only codes were a few U-codes (U0140, U0155) indicating lost communication with the BCM and Instrument Panel. After hours of diagnostics, we found that wiggling the main BCM connector could sometimes replicate the fault. A closer look at the original BCM’s circuit board revealed microscopic cracks near the main processor from years of thermal cycles. We performed our cloning service onto a replacement module, and the ‘ghost’ was gone for good. It’s a classic failure I’ve seen on dozens of these GM platforms.
Is Your Caprice Showing These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your 2014-2017 Caprice BCM is likely the cause:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up, causing alarm issues or no-start conditions.
- ✔ The key fob is no longer recognized by the vehicle.
- ✔ Random warning lights on the dashboard, such as the airbag or traction control light.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, like U0140.
Your Straightforward BCM Installation Guide
Our cloning service makes this a job most DIYers or any professional mechanic can handle easily. No special programming tools are required for the installation itself.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: In the 2014-2017 Caprice, the Body Control Module is typically located under the steering column, behind the lower dash panel.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Seat your new, pre-programmed BCM onto the mounting bracket and secure it. Firmly reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all functions: lights, locks, windows, radio, etc.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicle systems may require a quick recalibration after the BCM is replaced. This is a normal part of the process.
- ✔ Airbag System Sync: If your airbag warning light is on after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure brake lights and traction control function correctly. This is also performed with a scan tool.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will email you instructions and a prepaid shipping label to send your original BCM to us. Once we receive it, we extract the vehicle-specific data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you.
What if my original BCM is completely dead or ‘fried’?
In most cases, even if the BCM is non-functional in the car, we can still recover the necessary data. If for some reason the data is completely unrecoverable, we will contact you to discuss options, including a full refund.
Do I need to send my keys with the module?
No. Because we are cloning your original module’s data, the replacement unit will recognize your existing keys automatically. You do not need to send us your keys.
Is this a guaranteed fix for my 2014-2017 Caprice BCM problem?
This service corrects issues caused by a faulty BCM. While BCM failure is very common, it’s essential to ensure your vehicle has been properly diagnosed. This part will not fix problems related to wiring, sensors, or other modules.
Is there a core charge?
No, there is no core charge. We need your original module to perform the data transfer service, and we will ship it back to you along with the newly programmed replacement.
