Restore Full Electronic Functionality to Your Vehicle
Is your Cadillac STS or other GM vehicle plagued by strange and unpredictable electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or random warning lights on your dash often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of frustrating issues. This replacement Body Control Module, part number 25826124, is the definitive solution to restore your vehicle’s proper operation.
Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this module arrives at your door completely pre-programmed for your specific vehicle. Our technicians use your Vehicle Identification Number (VIN) to load the correct software and the latest updates from GM. This ensures a seamless installation process, getting you back on the road faster and with less hassle.
From the Diagnostic Bay
We recently had a 2009 GMC Acadia in the shop with a bizarre list of complaints. The owner reported that the key fob would only work intermittently, the rear liftgate would sometimes open on its own, and the radio display would randomly go blank. After checking for wiring faults and testing the battery, our diagnostics pointed towards a communication breakdown originating from the BCM. We installed a VIN-programmed 2010 STS Body Control Module (which shares the same architecture) and every single electrical gremlin vanished. It’s a classic case of how a single failing module can cause widespread, seemingly unrelated problems.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system acting up, causing false alarms or preventing the car from starting.
- ✔ Key fob not being recognized or working intermittently.
- ✔ Unexplained warning lights (like Airbag or ABS) on the instrument cluster.
- ✔ Wipers, horn, or radio not functioning correctly.

This plug-and-play approach saves you from costly dealership labor and diagnostic fees. Built to meet or exceed original equipment specifications, this BCM restores the reliable performance you expect from your vehicle.
Installation and Post-Install Procedures
Physically installing the BCM is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, after installation, some vehicles may require additional electronic ‘handshake’ procedures to ensure all systems communicate correctly.
- 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’ procedure. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM). This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary. This ensures the brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does a Body Control Module do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide variety of electronic accessories not related to the engine. This includes power windows, locks, lights, wipers, the security system, and more. It acts as a central gateway for these systems to communicate.
Do I need to take my car to a dealer after installing this BCM?
No. We pre-program the module to your vehicle’s VIN before shipping it. This means it arrives ready for installation, eliminating the need for a separate, costly programming session at a dealership. In some rare cases, a minor relearn procedure as described above may be needed.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot ship your part until we have programmed it, so providing the VIN promptly is essential.
Is there a core charge for this part?
No, there is no core charge for this Body Control Module. You can keep your original part without needing to send it back to us.
What if my airbag light comes on after I install the new BCM?
This is an indication that the BCM needs to be electronically synced with your vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade diagnostic tool to resolve this.
