Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your vehicle? Flickering lights, power windows with a mind of their own, or a security system that randomly acts up? These are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, when the BCM goes bad, it can cause a cascade of frustrating and unpredictable problems. For over 20 years, I’ve seen how a faulty BCM can sideline a perfectly good vehicle, leaving owners with hefty diagnostic and programming bills from the dealership.
This is where our unique Cloning Service comes in. We take the guesswork and high costs out of the repair. Instead of you needing to pay for expensive dealership programming, we transfer the critical data from your original BCM directly to this replacement unit. The module you receive will be a true plug-and-play solution, pre-configured with your vehicle’s specific identity and options using the VIN you provide. This restores function without the need for a trip to the dealer.
Case Study: A Tricky Diagnosis
I remember a 2012 Caprice PPV that came into the shop with a complaint of intermittent no-crank and random interior light failures. The battery and starter checked out fine. Scans showed a slew of communication loss codes (U-codes) with various modules. After tracing the wiring and finding no faults, we suspected the BCM. The intermittent nature of the problem was the key. We swapped in a cloned BCM, and the gremlins vanished. It’s often not a complete, hard failure but a slow degradation of the BCM’s internal processors that causes these ghost-like issues that are so hard to pin down.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system or keyless entry failing intermittently.
- ✔ A “Service Security System” or other warning messages on the dash.
- ✔ Communication error codes, such as U0140, U0155, or other U-codes, indicating a loss of communication with the BCM.
- ✔ In some cases, a no-start or no-crank condition due to security system malfunctions.
A Straightforward Guide to Your BCM Swap
Our cloning service makes the physical installation simple. Since the programming is done, you just need to swap the modules.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: In the 2011-2013 Caprice, the BCM is typically located in the cabin, often behind a kick panel on the driver’s or passenger’s side or under the dash. Consult a service manual for the exact location on your specific model.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, etc. Note the post-installation procedures below, as some may be required.
Important Post-Installation Information
After installing your cloned BCM, some vehicles may require one or more of the following procedures to ensure all systems communicate correctly. This is a normal part of the process.
- 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 accurate brake light operation and stability control function, a brake pedal position sensor relearn may be necessary.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific make and model.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the essential vehicle-specific software and security data from your original, failing BCM to this replacement unit. This makes the new module plug-and-play, saving you from costly and time-consuming dealership programming.
Do I need to program this module after I receive it?
No. Because we clone your original module’s data, this unit arrives ready for installation. In some cases, minor relearn procedures (like for the brake pedal sensor) may be required after installation, which can be done with a suitable scan tool.
How does the process work?
After you purchase, you will send us your original BCM. We will perform the cloning service and ship both your original module and the ready-to-install replacement back to you. We do not keep your original part.
What if my airbag light is on after installation?
This is not uncommon. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Where is the BCM located on my 2012 Caprice?
On the 2011-2013 Chevrolet Caprice, the Body Control Module is typically found behind the instrument panel, on the left-hand side near the steering column. It’s advisable to remove the lower dash trim panel for access.
