Restore Full Electronic Functionality to Your Vehicle
Is your 2006-2011 Cadillac DTS or other GM vehicle plagued by strange and unpredictable electrical problems? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your car’s body electronics, controlling everything from your power windows and door locks to the security system and interior lighting. When it fails, it can cause a cascade of frustrating issues that can be difficult to diagnose.
This is a direct replacement Body Control Module, part number 25847588, that solves these common failures. To make your repair as simple as possible, we program the module to your vehicle’s specific VIN before it ships. This critical step ensures the BCM communicates correctly with your car’s other systems, saving you a costly trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest.
Solving Common BCM Failures
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a replacement DTS Body Control Module is the likely solution. This module is the heart of your vehicle’s convenience and security features, and its proper function is essential.
Common Symptoms of a Bad BCM:
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on.
- ✔ The security or anti-theft system light is illuminated on the dashboard.
- ✔ Intermittent operation of the radio, climate controls, or instrument cluster gauges.
- ✔ Key fob not responding or vehicle failing to recognize the key.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False warning messages appearing on the driver information center.
Installation and Post-Install Procedures
After installing your pre-programmed DTS Body Control Module, some vehicles may require additional relearn or synchronization procedures. These are typically performed with a professional-grade scan tool. Common procedures include:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.

Frequently Asked Questions
Is this a plug-and-play part?
Mostly, yes. We pre-program the module to your vehicle’s VIN, which handles the most complex part of the installation. However, as noted, some vehicles may require minor additional relearn procedures for systems like the airbags or brake sensor, which require a diagnostic tool.
How do I provide my vehicle’s VIN?
You can add your 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email to request it before we can program and ship your module.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Where is the BCM located on a 2006-2011 Cadillac DTS?
On the Cadillac DTS, the Body Control Module is typically located behind the dashboard on the right-hand (passenger) side, near the center console area. Always consult a service manual for the exact location and removal procedure for your specific vehicle.
Will this fix my ‘Service Theft System’ warning?
A faulty BCM is a very common cause of the ‘Service Theft System’ message on these GM vehicles. While other issues can cause this warning, replacing a failed BCM that has been correctly programmed to your VIN will resolve the problem if the module was the root cause.
