Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with frustrating and unpredictable electrical problems in your Cadillac or GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central nervous system for your car’s body electronics, a faulty BCM can cause a cascade of issues that are not only annoying but can also compromise safety. This is a direct-fit, reliable solution for your 2010 STS Body Control Module and a wide range of other GM vehicles.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2010 Cadillac STS that came into my shop with a list of symptoms that sounded like a poltergeist had taken up residence. The dome lights would randomly turn on while driving, the driver’s side window wouldn’t respond, and the anti-theft light would flash intermittently, sometimes preventing the car from starting. The owner had already replaced the battery and checked fuses, but the gremlins persisted. After hooking up my diagnostic scanner, I saw multiple communication loss codes (U-codes) with various modules. This pointed directly to the BCM. Instead of a costly trip to the dealer, we installed a VIN-programmed BCM just like this one. The result? Every single issue vanished. It’s a perfect example of how a single component can wreak havoc, and why a correctly programmed replacement is the only real fix.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your BCM is the culprit:
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Vehicle security system issues, including no-start conditions.
- ✔ Inoperative remote keyless entry (fob).
- ✔ False warnings on the dashboard information center.
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs.
The Advantage: Programmed Specifically for Your Vehicle
Forget about expensive dealership visits and towing fees. We take the hassle out of the repair by programming this module with the latest GM software updates using the VIN you provide. This ensures that the BCM communicates perfectly with your car’s existing systems right out of the box. It’s a true plug-and-play repair that saves you time and money. Plus, there is no core charge, so you can keep your original part.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2010 Cadillac STS, the Body Control Module is typically located in the center dash area. For other models, its location can vary (e.g., under the steering column or behind the dash). A quick search for your specific model will confirm its location.
- ✔ Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old BCM and remove it.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions—lights, locks, windows, etc.—to confirm the repair was successful.
Important Post-Installation Information
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Depending on your specific model, you may need a professional scan tool to perform one of the following procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is necessary to sync the systems.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Do I need to get this programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during checkout, and it will arrive ready to install.
What is a VIN and where do I find it?
The VIN is your 17-digit Vehicle Identification Number. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is there a core charge or do I have to send my old part back?
There is absolutely no core charge. You can keep your old module.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). This procedure, called “Setup SDM Primary Key in BCM,” can be performed by a technician with a professional-grade diagnostic tool.
Will this work if my old part number isn’t 15872388?
Yes, this module is a compatible replacement for all the part numbers listed in the description. As long as your old part number is on our list, this module will work for you.
