Restore Full Functionality to Your GM Vehicle with a VIN-Programmed BCM
Is your vehicle plagued by strange and frustrating electrical problems? Power windows with a mind of their own, dashboard lights flickering randomly, or a security system that prevents you from starting the car? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central command for your car’s electronics, a faulty BCM can wreak havoc. This is the definitive, reliable solution for your 2010 STS Body Control Module and a wide range of other GM vehicles, restoring predictable performance and peace of mind.
We take the guesswork and high cost out of the repair. Unlike a blank module from a dealership that requires expensive programming, this BCM arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This means a simpler installation process, getting you back on the road faster without the need for a tow to the dealer.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2010 Cadillac STS that came into my bay with a list of symptoms that sounded like a poltergeist had taken up residence. The radio would switch stations, the interior lights would pulse, and the car intermittently wouldn’t recognize the key fob. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a flurry of communication error codes (U-codes) pointing to the BCM. The internal logic was failing, sending corrupt data across the vehicle’s network. We replaced it with a VIN-programmed module just like this one. The moment we connected the battery, everything worked perfectly. No more ghosts, just a happy customer. This is why a properly programmed 2010 STS Body Control Module is non-negotiable for a lasting repair.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. Replacing it can resolve these issues and prevent further electrical complications.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system or anti-theft light flashing, causing a no-start condition.
- ✔ Inconsistent horn or wiper operation.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or U0100.
- ✔ False warnings on the instrument cluster (e.g., “Service Theft System”).
Your Straightforward Path to Installation
Installing your new BCM is a manageable task for a confident DIYer. While the exact location varies by model (see fitment list), the general process is consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Locate the BCM: On the 2010 STS, it’s typically found in the center dash area. For other models, it may be under the steering column or behind the dash on the driver’s or passenger’s side.
- Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or lifted. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New Module: Seat the new BCM in the same position and secure it. Reconnect all electrical harnesses, ensuring they click securely into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test your electronics—windows, locks, lights, and radio.
- Perform Relearns (If Needed): Start the vehicle. If you see an airbag light or experience brake system issues, perform the necessary post-installation procedures outlined below.
Important Post-Installation Information
Because this module is pre-programmed, you’ve already skipped the hardest part! However, depending on your specific vehicle, a couple of simple relearn procedures may be required to sync the new BCM with other vehicle systems. These are standard procedures after a BCM replacement.
- 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” function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require this procedure to ensure the brake lights and traction control system function correctly. This can often be done with a high-end scan tool.
Disclaimer: We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and more, ensuring everything works in harmony.
Why is VIN programming so important?
Programming the BCM to your VIN ensures it works correctly with your vehicle’s specific options and security systems. Our service saves you a trip to the dealership and the high cost of their programming, making this a much simpler repair.
Do I need to return my old BCM?
No, there is absolutely no core charge for this part. You can keep your original module, saving you the time and expense of a core return.
Is this part difficult to install myself?
For someone with basic mechanical skills, this is a very manageable job. It primarily involves disconnecting the battery, locating the module, swapping a few electrical connectors, and then securing the new part. Our included instructions provide a clear guide.
What information do you need from me?
After you place your order, we will need your 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module with the correct software and options for your specific car before we ship it.
