Are you chasing electrical gremlins in your 2011-2013 Chevrolet Caprice? Flickering lights, malfunctioning power windows, or a dashboard that seems to have a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and difficult-to-diagnose issues. Stop the guesswork and restore your vehicle’s functionality with this direct-fit replacement Body Control Module.
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Before we ship your part, our technicians will program this Caprice Body Control Module with the latest GM software, perfectly matched to your vehicle’s specific VIN. This means it arrives at your door ready for installation, saving you hundreds in dealer fees and getting your car back to normal faster.
A Technician’s Notebook
I once had a 2012 Caprice PPV (Police Pursuit Vehicle) in my bay that was driving the department’s fleet manager crazy. The radio would cut out, the dome light would stay on, and occasionally the turn signals would stop working—all intermittently. Standard diagnostics were a dead end. After checking the main harnesses for chafing, I focused on the BCM. These modules are the traffic cops for dozens of electronic signals, and when they start to fail, the symptoms are often chaotic. Swapping in this pre-programmed module solved every single issue in under an hour. It’s a reliable fix that turns a potential diagnostic nightmare into a straightforward parts replacement.
Is Your Caprice Showing These BCM Failure Signs?
- ✔ Erratic or non-functional interior and exterior lighting (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, preventing the car from starting (Security light on).
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ Diagnostic trouble codes related to communication errors, such as U0140 (Lost Communication with BCM).
- ✔ Wipers or horn activating unexpectedly or not responding.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the Module: On the 2011-2013 Caprice, the BCM is typically located in the cabin, often behind a kick panel or under the dashboard. Consult a service manual for the exact position.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Be gentle with the locking tabs. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- ✔ Power Up: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and verify that your vehicle’s electronics are responding correctly.
- ✔ Perform Relearns: Depending on your vehicle, you may need to perform additional procedures. Please see the critical post-installation notes below.
Important Post-Installation Information
While this module is delivered programmed, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and stability control function, a brake pedal position sensor relearn may be required on some models.
- No Core Charge: You are not required to return your old module. This purchase has no core charge.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster. When it fails, these systems can become unreliable.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We will handle the programming before shipping the module to you.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. It typically involves removing a dash panel, unplugging the old module, and plugging in the new one. The key is that our pre-programming service saves you the most complex step.
What if my airbag light is on after installation?
This is not uncommon. It means the new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done by a repair shop with a professional-grade diagnostic tool.
Does this part come with a warranty?
Yes, all of our electronic modules come with a standard warranty that covers any defects in the part itself. Please refer to our store’s warranty policy page for complete details.
