Is Your Caprice Plagued by Electrical Gremlins?
As a technician with over two decades in the bay, I’ve seen it all. Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or worse—a car that refuses to start for no apparent reason. These baffling electrical issues in your 2011-2013 Chevrolet Caprice often point to one central culprit: a failing Body Control Module (BCM). The BCM is the nerve center for your vehicle’s comfort and security features, and when it starts to go, it can feel like your car is possessed.
Forget expensive dealership visits and the headache of programming a new module from scratch. We offer a straightforward, reliable solution. This listing is for a replacement BCM featuring our professional cloning service. You send us your original BCM, and we transfer its exact data—including key information and vehicle-specific options—to this replacement unit. The result? A true plug-and-play module that restores full functionality, programmed with the latest GM software updates tied to your VIN. It’s the smart, efficient fix that gets you back on the road without the dealership hassle.
A Technician’s Notebook
A few months back, a 2012 Caprice PPV was towed to our shop. The complaint was intermittent no-start and random dash warnings. The owner had already replaced the battery and checked the alternator. A scan showed a flurry of U-codes, specifically a U0140 (Lost Communication With Body Control Module). Instead of just throwing a new module in, we checked the BCM’s power and ground circuits—all solid. This confirmed the BCM itself was failing internally, likely from heat cycles causing micro-fractures on the circuit board. By using our cloning service, the fleet manager avoided a costly trip to the dealer and had the patrol car back in service the next day. It’s a classic failure mode for these units.
Symptoms of a Failing 2011-2013 Caprice BCM
If your vehicle is exhibiting any of these signs, a faulty BCM is the most likely cause. Don’t let these issues go unchecked, as they can worsen over time.
- ✔ Power windows, door locks, or interior lights operate erratically or not at all.
- ✔ The security system light stays on, preventing the engine from starting.
- ✔ Horn, wipers, or radio function intermittently.
- ✔ False warnings appear on the instrument cluster (e.g., “Service Airbag,” “Service Traction System”).
- ✔ Communication error codes are present, such as U0140, U0155, or other U-series codes.
- ✔ The vehicle won’t start, and the starter doesn’t engage, even with a good battery.
A Straightforward Guide to Installation
Our cloning service makes this a job most DIYers can handle. By transferring your original data, we eliminate the need for complex on-car programming.
- 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, often behind the lower dashboard panel on the driver’s side.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to release. Then, unbolt the module from its mounting bracket.
- Ship Us Your Module: Securely package your original BCM and send it to us. We handle the cloning process and ship both your original and the ready-to-install replacement back to you.
- Install the New BCM: Mount the cloned module in the same location, reconnect the electrical connectors, and re-secure the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all body functions (lights, locks, windows, etc.). In some cases, a relearn procedure may be needed. See below for details.
Important Post-Installation Notes
While our cloning makes this process seamless, some GM systems require a ‘handshake’ after a new module is introduced.
- Airbag System Sync: If the airbag light is on after installation, a simple “Setup SDM Primary Key in BCM” procedure must be performed with a capable scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure proper brake light and stability control operation. This also requires a professional diagnostic tool.
Disclaimer: Vehicle systems vary. Always have a factory service manual or a professional technician available for reference.

Frequently Asked Questions
What exactly is a ‘cloning service’?
Cloning is the process of reading the essential vehicle-specific data (like VIN, key codes, and optional features) from your original BCM and writing it directly onto the replacement module. This makes the new part a perfect digital copy of the old one, eliminating the need for expensive and complicated dealer programming.
Do I have to send you my original BCM?
Yes. For the cloning service to work, we need your original module to extract the data. We will return your original part along with the newly programmed replacement.
Is this a guaranteed fix for my car’s problems?
This BCM will fix problems directly caused by a faulty module. It’s crucial to properly diagnose the issue first. If your vehicle has wiring problems, faulty sensors, or bad grounds, this part will not resolve those underlying issues. The symptoms we’ve listed are the most common indicators of BCM failure.
Will I lose my key fob programming?
No. Because we are cloning your original module, all key fob and security information is transferred over. Your existing keys and remotes will work immediately after installation without any additional steps.
What if the airbag light comes on after I install it?
This is a normal security measure on some GM vehicles. The BCM and the airbag module (SDM) need to be electronically re-introduced. A mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to clear the light.
