Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your Cadillac, Chevrolet, or Buick? Flickering lights, malfunctioning power windows, a temperamental security system, or dashboard warnings that come and go are classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant frustration. It’s the central hub for your car’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can affect safety systems and drivability.
We offer a straightforward and reliable fix. This listing is for a replacement BCM that arrives at your door fully programmed and ready for installation. Our process is simple: you purchase this module, ship your original BCM to our facility, and we handle the rest. Our experts will clone all the critical data—including VIN, mileage, and key programming—from your original unit to this replacement. This means you can bypass the expensive dealership visit for programming. You get a part that is truly plug-and-play, saving you time, money, and headaches. For a professional mechanic or a skilled DIYer, this service for a 2013 ATS BCM is the most efficient path to a successful repair.
A Technician’s Notebook
I remember a 2013 Cadillac XTS that came into the shop with a complaint of the radio turning on and off by itself and the interior lights randomly strobing. The owner had already replaced the battery and checked the alternator. After scanning the vehicle, we found a slew of communication error codes (U-codes) all pointing back to the BCM. Instead of a complex rewiring job, we identified the BCM as the culprit. A cloned module like this one had the car fixed and back to the customer the same day it arrived, completely resolving all the bizarre electrical gremlins.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security system or keyless entry works intermittently or not at all.
- ✔ Dashboard warning lights (like airbag or traction control) appearing for no reason.
- ✔ Communication errors with other modules, often indicated by U-series diagnostic trouble codes (DTCs).
- ✔ Rapid battery drain while the vehicle is off, caused by the BCM failing to go into ‘sleep’ mode.
Our Simple Cloning and Installation Process
- ✔ Step 1: Place Your Order. Purchase this BCM, and we will contact you with instructions for shipping your original module to us. Please ensure your contact information is accurate.
- ✔ Step 2: Ship Your Original BCM. Carefully package and send us your vehicle’s original BCM. This is essential for the data cloning process.
- ✔ Step 3: We Program Your Replacement. Upon receiving your module, our technicians will transfer all necessary vehicle-specific data to the replacement BCM.
- ✔ Step 4: Install and Drive. We ship the programmed module back to you. Simply disconnect the battery, install the BCM, reconnect the battery, and your vehicle is ready to go. No core charge means you can keep your old part.
Important Post-Installation Information
While our cloning makes this a plug-and-play repair, some GM vehicles may require a quick sync procedure after installation. These do not occur in all cases but are important to be aware of:
- Airbag System Sync: If the airbag light is on 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: On some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and traction control function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service involves transferring the exact configuration data—like the VIN, security information, and vehicle options—from your original BCM to the replacement unit. This makes the new module plug-and-play, eliminating the need for expensive dealer programming.
Do I need to send my original BCM to you?
Yes, sending us your original module is a required step. We need it to extract the unique data for your vehicle to ensure the replacement BCM functions perfectly upon installation. We will contact you with shipping instructions after your purchase.
Is this part difficult to install?
For someone with moderate mechanical skill, replacing the BCM is generally straightforward. The main steps are disconnecting the battery, locating and swapping the module, and reconnecting the battery. The location varies by model, as noted in our fitment list.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
Is there a core charge for my old BCM?
No, there is no core charge. After we have cloned the data from your original module, you are welcome to keep it.
