Is Your Cadillac SRX Experiencing Strange Electrical Problems?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your interior and exterior lights to your power windows, door locks, and security system. When the BCM starts to fail in your 2007-2009 Cadillac SRX, it can cause a wide range of confusing and frustrating symptoms that may seem unrelated. A faulty BCM can make your vehicle feel unreliable and unpredictable.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing false alarms or preventing the car from starting.
- ✔ The dashboard displaying incorrect information or warning lights that won’t turn off.
- ✔ Issues with the keyless entry remote and push-button start system.
- ✔ Complete loss of power to various accessories, leading to a no-start condition.

Installation and Post-Install Notes
While this module is designed for direct installation, some vehicles may require additional steps to ensure all systems communicate correctly. 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: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
Is this BCM ready to install when I receive it?
Yes! This BCM is fully programmed to your vehicle’s VIN before we ship it. This makes the installation process much simpler than buying a blank module that requires dealer programming.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it.
What if my airbag light is on after I install the BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Will this part fit vehicles other than the Cadillac SRX?
Yes, this BCM is compatible with a wide range of GM vehicles, including models like the Acadia, Enclave, Traverse, Impala, and various Express/Savana vans. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
