Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Is your Cadillac CTS, or another compatible GM vehicle, suffering from baffling electrical issues? Problems like flickering lights, malfunctioning power windows, a haywire security system, or random warning lights on the dash are often symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable problems. Don’t let a faulty module keep your car off the road. This replacement Body Control Module, part number 25826125, is the definitive solution to restore your vehicle’s proper function and reliability.
From the Diagnostic Bay
We had a 2011 Cadillac CTS come into the shop with a list of complaints the owner called “automotive ghosts.” The radio would change stations on its own, the interior lights would pulse dimly at night, and the driver’s side window would occasionally refuse to go up. Other shops had replaced the battery and checked the alternator, but the problems persisted. After hooking up our diagnostic scanner, we saw multiple communication fault codes pointing to the BCM. A visual inspection revealed no obvious damage, but a deep data scan showed erratic voltage outputs from the module itself. We installed one of our pre-programmed BCMs matched to the customer’s VIN. In less than an hour, every single ghost was busted. The car behaved perfectly, and the customer was thrilled to have their luxury car back without the dealership price tag.
Is Your Vehicle Exhibiting These BCM Failure Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ Dashboard lights (like the airbag or security light) staying on or flashing randomly.
- ✔ The anti-theft or security system preventing the car from starting.
- ✔ Headlights, taillights, or interior lights turning on or off by themselves.
- ✔ Windshield wipers behaving unpredictably or not parking in the correct position.
- ✔ Climate control fan speed or mode door actuators not responding correctly.
- ✔ Key fobs that suddenly stop working for locking, unlocking, or remote start.

This critical step ensures that all systems communicate correctly, saving you a mandatory and expensive trip to the dealership for programming. It’s designed for a seamless installation process, getting you back on the road faster.
Installation and Post-Install Procedures
While this module is designed for a straightforward swap, modern vehicles require certain systems to be re-synchronized after a new module is introduced. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
- No Core Charge: We make it simple. There is no core charge on this module, so you can keep your original part without the hassle of shipping it back.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the precise software and settings for your car’s specific options, such as the type of transmission, security system, and other electronic features. This ensures a true plug-and-play experience without needing dealer intervention.
Is this a difficult part to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module, which is often located under the dash. However, post-installation electronic relearn procedures, like for the airbag or brake systems, may require a professional-grade scan tool. Many experienced DIY mechanics can perform the swap.
What happens if I don’t perform the post-install procedures?
If required for your vehicle, skipping these procedures can leave warning lights on (like the airbag light) and may cause certain features, such as the traction control system, to function incorrectly. It is crucial to ensure all systems are properly synced after installation.
How can I be sure my BCM is the problem?
Matching your vehicle’s issues to the common symptoms listed above is a strong indicator. For a definitive diagnosis, having a qualified technician scan the vehicle for communication codes (U-codes) and test the BCM’s inputs and outputs is the best method.
Do I need to send my old BCM back?
No. This product comes with no core charge. You are free to keep or dispose of your original module without any additional fees or hassle.
Will this fit vehicles other than the Cadillac CTS?
Yes, absolutely. This BCM is compatible with a wide range of GM models, including the Chevy Impala, GMC Acadia, Buick Enclave, Chevy Traverse, and many more. Please refer to the detailed fitment list on this page to confirm compatibility with your specific vehicle.
