Restore Your Vehicle’s Electrical System with a Pre-Programmed BCM
Are you battling frustrating and unpredictable electrical issues in your vehicle? Intermittent power windows, flickering lights, a malfunctioning security system, or strange warning messages on your dash are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of problems that are difficult to diagnose. This replacement Body Control Module, part number 15819552, is the definitive solution to restore full functionality and reliability to your vehicle’s essential features.
Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this module arrives at your door ready for installation. We use your vehicle’s Vehicle Identification Number (VIN) to flash the unit with the latest, most stable software updates directly from GM. This ensures perfect communication between the BCM and all other modules in your car, eliminating compatibility issues and saving you hundreds of dollars in programming fees and towing costs. By providing your VIN upon purchase, you are getting a component that is specifically prepared for your vehicle’s exact configuration.
From the Diagnostic Bay
We had a 2010 Cadillac STS come into the shop with a laundry list of bizarre electrical gremlins. The owner reported that the radio would turn on by itself, the driver’s side window would only work occasionally, and the anti-theft light would flash randomly, sometimes preventing the car from starting. After hours of checking wiring diagrams and testing individual components, all signs pointed to an internal failure in the BCM. Instead of a costly dealer replacement, we installed one of our VIN-programmed modules. The installation was straightforward, and upon starting the vehicle, every single issue was resolved. The customer was thrilled to have their luxury car’s features working perfectly again without the massive dealership bill.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indication that your BCM needs replacement:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not turning on.
- ✔ The security system acting up, causing false alarms or no-start conditions.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ Warning lights such as ABS, Airbag, or Traction Control illuminating without a clear cause.
- ✔ Remote keyless entry failing to lock or unlock the doors.
- ✔ Wipers or climate control systems behaving unpredictably.
The Importance of a VIN-Programmed 2010 STS Body Control Module
Modern vehicles are complex networks of computers that must communicate seamlessly. The BCM is a critical hub in this network. Installing a generic, non-programmed module will simply not work. It won’t recognize your vehicle’s specific options, security keys, or other electronic components. Our programming service bridges this gap. We take the information from your VIN to load the correct software and settings for your exact model, trim, and feature set. This makes the installation process as close to plug-and-play as possible, restoring your vehicle to its original factory operation. This unit is a direct replacement for a wide array of GM part numbers, ensuring broad compatibility across models like the Equinox, Impala, Acadia, Tahoe, and many more.
Installation and Post-Install Procedures
After installing your new BCM, some vehicles may require additional relearn or synchronization procedures to ensure all systems function correctly. While our programming handles the majority of the setup, you may need a professional scan tool for the following:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be required on certain models.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions. There is no core charge for this part, so you can keep your original module.
Frequently Asked Questions
Is this part truly plug-and-play?
Because we program the module to your specific VIN, it is as close to plug-and-play as possible. It will have the correct software for your vehicle’s features. However, as noted, some vehicles may require minor post-installation procedures like an airbag sync or brake pedal position relearn, which require a diagnostic tool.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the module until we have programmed it with your VIN.
Will this fix my car’s specific electrical problem?
This module will correct issues that are directly caused by a faulty BCM. The symptoms listed above are strong indicators of BCM failure. However, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes like bad wiring, grounds, or faulty switches.
Is there a core charge for this module?
No, there is absolutely no core charge. You are not required to send your old, faulty BCM back to us. You can keep it or dispose of it as you see fit.
What if the part numbers don’t match exactly?
This module replaces a long list of interchangeable GM part numbers, including 10382479, 15828601, 20815898, and many others listed in the description. As long as your original part number is on our compatibility list, this module will be the correct replacement for your vehicle.
