Important Post-Installation Steps
While this module is programmed for your vehicle, some models may require additional synchronization steps after installation. These procedures may need to be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is required to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary to ensure proper brake light and traction control function.
Please consult a factory service manual or a qualified professional for vehicle-specific instructions.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle responsible for monitoring and controlling various electronic accessories, such as power windows, lighting, security systems, door locks, and wipers. When it fails, these systems can behave erratically.
Why do you need my Vehicle Identification Number (VIN)?
Your VIN is essential for us to program the BCM with the correct software and vehicle-specific options for your Cadillac CTS. This ensures the module works seamlessly with your car’s existing systems without requiring expensive dealership programming.
Is this a difficult part to install?
The physical installation is typically straightforward for someone with moderate mechanical skill, as it involves unplugging the old module and plugging in the new one. However, some vehicles may require post-installation procedures (like an airbag or brake sensor relearn) that need a professional scan tool.
What if my original part number isn’t on the list?
The provided list is extensive, but if your part number is not shown, please contact us with your vehicle’s VIN. We can verify compatibility and ensure you receive the correct module for your car.
What are the post-installation procedures?
Depending on your specific vehicle, you may need to perform a relearn procedure for the airbag system (if the light is on) or the brake pedal position sensor. These procedures require a professional-grade diagnostic tool to complete.
Will this fix my ‘Service Theft System’ message?
A failing BCM is a very common cause of a ‘Service Theft System’ message and no-start conditions. Because our module is programmed to your VIN, it correctly communicates with the anti-theft system, often resolving this specific issue.
