Are you experiencing frustrating electrical issues with your 2008-2013 Cadillac CTS? Problems like flickering lights, unresponsive power windows, or a malfunctioning security system are often signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
This is not just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific VIN, loading it with the latest software updates from GM. This critical step ensures compatibility and proper function of all your vehicle’s features, saving you a costly trip to the dealership for programming. Simply provide us with your VIN after purchase, and we’ll handle the rest, shipping you a module that’s ready for installation.
From the Diagnostic Bay
We had a 2011 CTS in the shop that was driving its owner crazy. The radio would randomly turn off, the driver’s side window wouldn’t work, and the alarm would go off for no reason. We scanned for codes and found a slew of communication errors all pointing back to the BCM. Instead of a complicated diagnostic path, we knew the fix was a reliable BCM. By installing a VIN-programmed module like this one, we had the car’s electronics working perfectly in under an hour, saving the customer hundreds in diagnostic and programming fees at the dealer.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights.
- ✔ Keyless entry or security system problems, including ‘Service Theft System’ warnings.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Dashboard warning lights illuminating without a clear cause.
- ✔ Communication loss codes (U-codes) when scanned with a diagnostic tool.
- ✔ Wipers or radio turning on or off by themselves.
Why Choose Our Pre-Programmed 2008-2013 CTS Body Control Module?
Getting your Cadillac back on the road shouldn’t be a hassle. Our process is designed to be simple and effective. By matching the software to your VIN, we ensure that the module you receive is a perfect match for your vehicle’s specific options and configuration. This direct-fit, pre-programmed module eliminates the guesswork and additional costs associated with a standard replacement.
Installation and Post-Install Procedures
While installation is straightforward for many, some vehicles may require minor post-installation steps to ensure all systems are synchronized. Please be aware of the following potential procedures:
- Airbag System Sync: If the 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: To ensure correct brake light operation and traction control function, a brake pedal position sensor recalibration may be necessary.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This saves you the time, hassle, and expense of a dealership visit.
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your VIN, or add it as a note during checkout. We will confirm with you before programming and shipping.
What if my original part number is not 15872421?
This module is compatible with a long list of interchangeable part numbers. Please review the list provided in the description. As long as your original part number is on that list, this module will work for your vehicle.
Is this a simple plug-and-play installation?
For most vehicles, it is. You disconnect the old BCM and connect the new one. However, as noted in the description, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
