Restore Full Electrical Function to Your Vehicle
If you’re dealing with bizarre and frustrating electrical gremlins in your 2011-2013 Chevrolet Caprice, a failing Body Control Module (BCM) is often the culprit. As a technician with over two decades of experience, I’ve seen it all: lights flashing for no reason, power windows and locks with a mind of their own, and security system alerts that prevent the car from starting. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing issues.
This isn’t just another part; it’s a complete solution. We offer a professional cloning service for this 2011-2013 Caprice BCM. This means you send us your original, faulty module, and we transfer all of its specific programming—including the VIN, security information, and optional features—to this fully functional replacement unit. The result? You receive a module that is truly plug-and-play. No expensive trips to the dealership for programming, no special scan tools required. It’s the most efficient and cost-effective way to get your car back to 100%.
A Technician’s Notebook: The Water Intrusion Problem
I once had a 2012 Caprice PPV in the shop that was driving its owner crazy. The dome lights would stay on, the horn would honk randomly when locked, and the radio presets would disappear. The initial thought was multiple separate failures, but experience pointed me to the BCM. After locating the module under the driver’s side dash, I noticed a faint line of corrosion on one of the connectors. A quick check revealed a small, persistent leak from a poorly sealed windshield cowl. That moisture was enough to slowly destroy the delicate circuits inside the BCM. This is a common story for many GM vehicles of this era. Replacing the module with our cloned unit and fixing the leak provided a permanent, reliable fix.
Is Your Caprice Showing These BCM Failure Signs?
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The vehicle’s security system acts up, causing intermittent no-start conditions.
- ✔ Horn honking unexpectedly or the alarm sounding without reason.
- ✔ Communication error codes, particularly U-codes (e.g., U0140), stored in the system.
- ✔ Wipers turning on by themselves or not working when commanded.
- ✔ Incorrect information displayed on the driver information center (DIC).
Your Straightforward BCM Swap Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2011-2013 Caprice, the Body Control Module is typically located in the cabin, under the driver’s side of the dashboard. 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 New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- ✔ Power Up: Reconnect the negative battery terminal.
- ✔ Verify the Fix: Start the vehicle and test all the functions that were previously malfunctioning—lights, locks, windows, etc. Because this is a cloned unit, no further programming is needed.
Important Post-Installation Checks
While our cloning service makes this a direct swap, some vehicle systems may require a relearn procedure to fully sync with the new BCM. These are simple procedures for a professional technician with a capable scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after the swap, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the airbag system with the BCM. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified professional for your specific model.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the exact software, VIN, and security data from your original BCM to this replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for expensive dealership programming.
Will I need to program this module at the dealership?
No. Because we clone the data from your original module, this replacement BCM arrives ready for installation. Simply plug it in, and you’re good to go. This saves you significant time and money.
Where is the BCM located on my 2011-2013 Caprice?
The Body Control Module on this model is typically found inside the vehicle’s cabin, mounted under the dashboard on the driver’s side. You may need to remove a plastic trim panel to gain access.
My airbag light is on after installation. What do I do?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag’s Supplemental Deployment Module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the vehicle-specific data. After your purchase, we will provide instructions for sending it to us. We will return your original module along with the newly programmed replacement.
