Installation and Post-Install Notes
Installation is typically straightforward, but please be aware of potential post-installation procedures. While we handle the primary programming, some vehicle systems may require a ‘handshake’ with the new BCM. For instance, if your airbag light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control function. These procedures are model-dependent and can often be performed by any competent local repair shop if needed. Always consult a service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, lights, wipers, security system, and climate controls.
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you from additional programming costs and dealer visits.
Where is the BCM located on a 2008-2013 Cadillac CTS?

What if my airbag light is on after I install the new BCM?
If the airbag light illuminates, it means the BCM needs to be synced with the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade diagnostic tool.
