Are you experiencing frustrating and unpredictable electrical problems in your 2006-2011 Cadillac DTS? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and disruptive symptoms. This isn’t just an inconvenience; it can affect the security and proper operation of your luxury sedan.
We offer a reliable and straightforward solution: a replacement Body Control Module, part number 25910474, that arrives at your door fully programmed for your specific vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our technicians will flash the module with the latest official GM software updates. This critical step ensures the BCM communicates perfectly with your vehicle’s other electronic systems, eliminating the need for an expensive trip to the dealership for programming. It’s the most efficient way to restore your Cadillac’s functionality and peace of mind.
From the Diagnostic Bay
We recently had a 2009 Cadillac DTS in the shop with a classic “phantom drain” that was killing the battery overnight. The owner had already replaced the battery twice and even the alternator, with no luck. After connecting our diagnostic tool, we noticed that several modules on the communication network weren’t going to sleep after the key was off. The culprit? The BCM. It was sending erratic signals, keeping the radio and instrument cluster partially active. A new, properly programmed BCM solved the problem instantly. It’s a reminder that the BCM’s health is critical for the entire electrical ecosystem of the vehicle.
Common Symptoms of a Failing DTS Body Control Module
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ False alarms from the factory security system or issues with keyless entry.
- ✔ Warning lights on the dashboard with no apparent cause.
- ✔ Unexplained battery drain that kills the battery when the car is parked.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.
- ✔ Erratic behavior of the radio, climate control, or instrument cluster.
Plug-and-Play Solution with VIN Programming
Don’t settle for a generic module that requires complex and costly dealer intervention. Our service is designed for both professional technicians and savvy DIYers. By programming the module to your VIN before shipping, we ensure that it has the correct software and configuration for your DTS’s specific options and features. This process helps to avoid compatibility conflicts and simplifies the installation process significantly. This module is a direct replacement for a wide range of original part numbers, including 15828601, 20864767, 25826124, 25910474, and many more, ensuring broad compatibility across numerous GM models.
Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require minor additional procedures after the new BCM is installed. These are standard industry procedures and can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light illuminates after installation, a “Setup SDM Primary Key in BCM” procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct operation of brake lights and stability control systems.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What exactly does a Body Control Module do on a Cadillac DTS?
The BCM acts as the main computer for your car’s body electronics. It controls non-engine related functions such as power windows, locks, interior and exterior lighting, wipers, the security system, and the climate control fans, among other things.
Is this BCM difficult to install?
The physical installation is typically straightforward for someone with moderate mechanical skill. The BCM is usually located under the dashboard. Since we pre-program the unit to your VIN, you avoid the most difficult part of the job, which is the software setup. However, some post-install relearn procedures may be necessary.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function correctly in your vehicle.
What happens if my airbag light is on after installation?
This is a known possibility. The new BCM needs to be electronically “introduced” to the airbag control module (SDM). This requires a professional diagnostic tool to perform the “Setup SDM Primary Key in BCM” procedure, which syncs the modules and turns off the light.
Will this BCM fit vehicles other than the Cadillac DTS?
Yes. This module is compatible with a wide variety of GM vehicles, including models like the Chevy Impala, GMC Acadia, Chevy Express van, and Buick Lucerne, among others. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
