Restore Full Electronic Functionality to Your Cadillac DTS
Is your 2006-2011 Cadillac DTS suffering from bizarre electrical issues? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of frustrating problems, from flickering lights to a car that won’t start. This replacement BCM is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming, allowing for a straightforward installation.
From the Diagnostic Bay
We had a 2008 DTS come into the shop with a complaint of the interior lights staying on, intermittently killing the battery. The owner had already replaced the battery twice. After checking for shorts and parasitic draws, all diagnostics pointed to an internal failure in the BCM. Instead of a costly and time-consuming dealer visit, we installed one of our VIN-programmed modules. The swap took under an hour, and the electrical gremlins were gone for good. The customer was thrilled to have their luxury car back to normal without the dealership hassle.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system preventing the car from starting.
- ✔ False warnings on the instrument cluster (e.g., “Service Airbag,” “Service Traction System”).
- ✔ HVAC (heating and air conditioning) controls not responding.
- ✔ Remote keyless entry failure.
- ✔ Diagnostic trouble codes (especially U-codes) indicating a loss of communication.
Why Choose Our Pre-Programmed DTS Body Control Module?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM module and flash it with the most current software updates using your vehicle’s unique VIN. This ensures perfect compatibility with all the features and options your DTS was built with. By handling the programming beforehand, we save you hundreds of dollars and significant time, turning a complex repair into a manageable one.
Installation and Post-Install Notes
After you purchase, simply provide us with your vehicle’s 17-digit VIN. We will program the module and ship it to you, ready for installation. While the physical swap is often simple, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on 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 relearn to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic systems. This includes power windows, locks, lights, the security system, wipers, and climate controls.
Is this part truly plug-and-play?
Yes, it is designed to be as close to plug-and-play as possible. We program it to your VIN before shipping, which handles the most complex part of the installation. However, as noted, some vehicles may require minor relearn procedures for systems like the airbags or brake sensor.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive and validate your VIN.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A qualified technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
