Restore Your Vehicle’s Electronic Stability and Functionality
Is your 2011-2013 Chevrolet Caprice experiencing bizarre electrical problems? Issues like flickering lights, malfunctioning power windows, a security system that acts up, or even a no-start condition can often be traced back to a single, central component: the Body Control Module (BCM). As the electronic nerve center for your vehicle’s body-related functions, a failing BCM can cause a cascade of frustrating and seemingly unrelated symptoms. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability.
We offer a dependable and straightforward solution. This is a direct-replacement Body Control Module, compatible with part number 15921352 and many others. The key to our service is the included VIN-based cloning. You send us your original module, and we transfer its specific data to this replacement unit. This process ensures that all your vehicle’s original settings and security information are preserved, eliminating the need for a costly trip to the dealership for programming. You receive a module that is ready to install, getting you back on the road quickly and confidently.
A Technician’s Notebook
I remember a 2012 Caprice PPV that came into the shop with a classic “ghost in the machine” complaint. The dome lights would stay on, the radio would randomly shut off, and the key fob worked intermittently. The customer had already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to the BCM. These modules, especially on high-service vehicles, can suffer from internal circuit board failures due to heat cycles and vibrations over thousands of hours. By providing a data-cloned 2011-2013 Caprice BCM, we were able to solve all the electrical gremlins in one shot, saving the client hundreds compared to a new module and dealer programming.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors behaving erratically or not working at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to illuminate.
- ✔ The security system alarm sounding for no reason or preventing the car from starting.
- ✔ Intermittent operation of the radio, climate controls, or dashboard warning lights.
- ✔ Communication error codes stored in the system, such as U0140 (Lost Communication With Body Control Module).
- ✔ A complete no-start condition where the starter doesn’t even engage.
A Straightforward Guide to BCM Replacement
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any work on the electrical system.
- ✔ Locate the BCM: On the 2011-2013 Caprice, the Body Control Module is typically located in the passenger compartment, often under the dashboard on the driver’s or passenger’s side. Consult a service manual for the exact position.
- ✔ Remove the Old Module: Carefully disconnect all electrical connectors leading to the BCM. They have locking tabs that must be depressed to be removed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Send Us Your Module: Package your original BCM securely and ship it to us. We will perform the cloning service and send both your original module and the ready-to-install replacement back to you.
- ✔ Install the New Module: Mount the programmed replacement BCM and reconnect all electrical connectors, ensuring they click securely into place.
- ✔ Post-Installation Checks: In some cases, additional steps may be needed. If the airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. A Brake Pedal Position relearn might also be necessary for certain models.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we transfer the essential software and vehicle-specific data (like key information and options) from your original, faulty BCM to this replacement unit. This makes the new part plug-and-play, avoiding the need for expensive programming at a dealership.
Do I need to send my original BCM to you?
Yes. To perform the cloning service and ensure the replacement module works perfectly with your vehicle’s existing systems, we must have your original module. We will return your original part along with the newly programmed replacement.
Will this fix my specific problem?
This module resolves issues directly caused by a faulty BCM. If you’re experiencing problems like erratic lights, non-functional power accessories, or security system faults, a failing BCM is a very likely culprit. Proper diagnosis is key, but these are hallmark symptoms.
Is this a difficult part for a DIY mechanic to install?
For someone with basic mechanical skills, the replacement is very manageable. The main challenge is usually accessing the module under the dashboard. Since our service handles the programming, the most complex part of the job is already done for you.
What happens if my airbag light comes on after installation?
This can occasionally happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A professional-grade scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function to resolve this.
