Is your Cadillac CTS or other GM vehicle suffering from strange and unpredictable electrical problems? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from power windows and locks to interior lighting and the security system. When it fails, it can create a cascade of frustrating issues that seem to have no logical cause.
This is a direct-replacement Body Control Module, part number 15819552, for a wide range of GM vehicles, including the 2008-2013 Cadillac CTS. The greatest benefit of this part is that it arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM software updates, eliminating the need for an expensive trip to the dealership for programming. This makes the installation process as simple as possible, getting you back on the road quickly and reliably.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Dashboard warning lights appearing randomly.
- ✔ Communication issues with diagnostic scan tools.

Installing Your 2008-2013 CTS Body Control Module
Installation is straightforward, but post-install procedures may be necessary depending on your specific vehicle. After swapping the module, some systems may need to be re-synced. For example, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be required to ensure proper brake light and traction control function. Always consult a factory service manual for your specific model.
To ensure a perfect match, simply provide us with your vehicle’s VIN after purchase. We’ll handle the programming, so you receive a true plug-and-play solution. This part is a reliable fix for your 2008-2013 CTS Body Control Module and many other compatible vehicles.
