Restore Your Vehicle’s Electrical System with a Reliable BCM
If you’re dealing with bizarre and frustrating electrical issues in your 2011-2013 Chevrolet Caprice, a failing Body Control Module (BCM) is often the culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of problems that are difficult to diagnose. From flickering lights and malfunctioning power windows to a car that won’t start, these symptoms can disrupt your daily life. This replacement Body Control Module, part number 15921353, is the direct-fit, reliable solution you need to get your vehicle back in top condition.
We take the guesswork and hassle out of the replacement process. Unlike a generic part from a local store, this module comes pre-programmed to your specific vehicle. Simply provide us with your VIN after purchase, and our technicians will flash the unit with the latest GM software updates. This ensures seamless integration with your Caprice’s existing systems, saving you a costly trip to the dealership for programming. This is the most efficient way to solve complex electrical problems and restore the functionality you depend on.
From the Diagnostic Bay: The Caprice with a Mind of Its Own
I remember a 2012 Caprice PPV that came into the shop with a list of complaints that seemed unrelated. The dome light would stay on, the driver’s side power lock worked intermittently, and the radio would sometimes shut off on its own. The officer driving it was convinced it was haunted. We checked for bad grounds and wiring issues, but everything looked solid. A deep scan showed several U-codes (communication errors) pointing to the BCM. After replacing the original BCM with a pre-programmed unit like this one, every single ‘ghost’ in the machine vanished. It’s a perfect example of how a single failing 2011-2013 Caprice BCM can create widespread, confusing symptoms.
Common Signs Your Caprice BCM is Failing
The Body Control Module manages a wide array of functions. If you notice any of the following, it might be time for a replacement. A failing BCM can often trigger communication error codes like U0140, U0155, or other related DTCs.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry acting up or failing completely.
- ✔ The horn sounding randomly or not working at all.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Climate control system malfunctions.
Your Step-by-Step BCM Replacement Guide
Installing your new 2011-2013 Caprice BCM is a straightforward process for a DIYer with basic tools. Since this module is pre-programmed, you can avoid the complexities of dealership software tools for the initial setup.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In the 2011-2013 Caprice, the BCM is typically located behind the driver’s side of the dashboard, often near the steering column or kick panel.
- Access the Module: You may need to remove lower dash panels or trim pieces to gain clear access to the BCM. Keep track of any screws or clips you remove.
- 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 and remove it from the vehicle.
- Install the New BCM: Mount the new, pre-programmed BCM in the same location and reconnect all electrical connectors, ensuring they click securely into place.
- Post-Installation Checks: Re-install any trim panels you removed and reconnect the battery. Start the vehicle and test all body functions (lights, locks, windows, etc.). Note that some vehicles may require the post-install procedures listed below.
Important Post-Installation Information
While our programming handles the core functions, some vehicle systems may need to be re-synced after installation.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
- No Core Charge: You are not required to send your old part back. This saves you time and the cost of return shipping.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to program the BCM with the exact software and vehicle-specific options for your Caprice. This ensures the module works correctly right out of the box, just like one from the factory.
Is this a plug-and-play part?
Yes, for the most part. Because we pre-program it to your VIN, it eliminates the need for initial dealer programming. However, as noted, some vehicles may require a simple relearn procedure for specific subsystems like the airbag or brake pedal sensor, which may require a capable scan tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module, saving you the hassle and expense of shipping it back.
Will this fix a ‘Service Security System’ message?
A faulty BCM is a very common cause of security system errors and vehicle immobilizer issues. While other components can be at fault, replacing a diagnosed bad BCM often resolves these problems.
What if the airbag light comes on after I install it?
This indicates the new BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). A professional mechanic with a capable diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
