Is Your Cadillac CTS Plagued by Baffling Electrical Problems?
There’s nothing more frustrating than when the sophisticated electronics in your Cadillac CTS start acting up. One moment everything is fine, and the next you’re dealing with flickering lights, unresponsive power windows, or a car that refuses to start. These aren’t just minor annoyances; they compromise your vehicle’s luxury, safety, and reliability. The problem often lies with a failing Body Control Module (BCM), the central nervous system for your car’s body electronics. This isn’t a part you can simply swap out. It requires precise vehicle-specific programming. That’s where we come in.

An Expert’s Note on VIN Programming
“In vehicles like the Cadillac CTS, the BCM is the traffic cop for dozens of electronic systems, from the power seats to the anti-theft system. For security and functionality, it’s digitally ‘handshaken’ to your specific vehicle’s VIN. In the past, this meant a new BCM was just a plastic box until a dealer programmed it with their specialized tools for hundreds of dollars. Our service replicates that dealership-level process *before* we ship the part to you. You receive a module that your car instantly recognizes as its own, restoring full function and communication between all systems right out of the box.”
Guaranteed Fitment & Part Number Compatibility
After purchase, simply provide us with your vehicle’s 17-digit VIN, and we will handle the programming. This programmed 2008-2013 Cadillac CTS body control module is a direct replacement for the following part numbers:

Important Post-Installation Steps
While our programming handles the primary functions, some GM vehicles may require one or two simple relearn procedures after installation to sync all systems perfectly.
- 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, interior/exterior lighting, security systems, wipers, and more.
Is this module difficult to install?
The physical installation is typically straightforward for someone with basic mechanical skills. It usually involves disconnecting the battery, removing a few dash panels, and unplugging the old module to plug in the new one. Because we pre-program it, you avoid the complex computer setup required at a dealership.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as it is essential for the programming process.
Why is programming so important for a BCM?
The BCM is coded to a specific vehicle’s VIN and its unique set of options (like power seats, sunroof, etc.). An unprogrammed module will not communicate correctly with the other computers in the car, leading to system failures or a no-start condition. Our service handles this for you.
What if the airbag light comes on after installation?
This is a normal possibility on some GM vehicles due to security protocols. The BCM and the airbag module (SDM) need to be electronically re-introduced. A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my specific electrical problem?
This module is the solution for a wide range of common electrical failures. If your vehicle’s symptoms match those listed and a professional diagnosis has pointed to the BCM, this part is the correct fix. We always recommend proper diagnostics to confirm the BCM is the root cause before ordering.
