Restore Full Functionality to Your GM Vehicle
Are you battling a frustrating list of electrical gremlins in your Cadillac STS or another GM vehicle? Intermittent power windows, flickering dash lights, a security system that acts up, or even a no-start condition can often be traced back to one component: a failing Body Control Module (BCM).

We take the complexity out of the repair. Simply provide your vehicle’s VIN after purchase, and our technicians will program this module with the latest GM software specific to your car. This means when it arrives, it’s ready for installation. You’re not just buying a part; you’re buying a complete, ready-to-install solution for your 2010 STS Body Control Module needs and many other compatible vehicles.
A Technician’s Notebook: The DTS with a Ghost
I once had a 2008 Cadillac DTS in my bay that was driving its owner crazy. The radio would turn on by itself, the door locks would cycle randomly while driving, and occasionally, it wouldn’t start, showing only a ‘Service Theft System’ message. The battery was new, and the alternator checked out. After connecting my scan tool, I found a slew of ‘Lost Communication’ codes (U-codes) pointing to the BCM. A failing BCM can corrupt the data network, causing these seemingly unrelated, ghost-like problems. Installing a VIN-programmed module like this one resolved every single issue instantly. It’s a common failure I’ve seen dozens of times on this GM platform.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors work intermittently or not at all.
- ✔ The security system light is on, or the vehicle won’t start due to an anti-theft issue.
- ✔ Interior or exterior lights flicker, stay on, or don’t turn on.
- ✔ The horn sounds randomly or doesn’t work.
- ✔ Your scan tool shows communication error codes like U0140, U0155, or U0100.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
A Straightforward Guide to Installation
Replacing the BCM is a manageable job for a confident DIYer. While the exact location varies by model (as noted in the fitment list), the general process is consistent. Here’s a typical procedure for a 2010 STS Body Control Module replacement:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the BCM: On the 2010 Cadillac STS, the BCM is typically located in the center dash area. You may need to remove a lower dash panel or glove box for access.
- Disconnect and Remove: Carefully disconnect the electrical connectors. Most have a locking tab that needs to be pressed or lifted. Once disconnected, unbolt or unclip the old module and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, 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 all body functions: windows, locks, lights, radio, etc.
- Perform Relearns (If Needed): Start the vehicle. If you see an airbag light or notice issues with brake lights, proceed with the post-installation procedures noted below.
Important Post-Installation Steps
Because this 2010 STS Body Control Module is pre-programmed, most functions should work immediately. However, depending on your specific vehicle, a couple of additional sync procedures may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.

Yes. Providing your Vehicle Identification Number (VIN) is essential. We use it to program the module with the correct software and calibrations for your specific vehicle, ensuring a seamless installation.
Is this a simple plug-and-play installation?
For most vehicles, yes. Because we pre-program the module, you can typically install it and have all functions restored. In some cases, as noted above, minor relearn procedures for the airbag or brake systems may be needed using a professional scan tool.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which saves you the time and expense of shipping it back.
Will this fix my ‘Service Theft System’ light?
A faulty BCM is a very common cause of anti-theft system problems in these GM vehicles. While other issues can cause this warning, replacing a bad BCM often resolves the issue. Our VIN-specific programming ensures the security information matches your vehicle’s keys.
