Is your 2007-2009 Cadillac SRX suffering from baffling electrical problems? The Body Control Module, or BCM, is the central command for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement Body Control Module, part number 15921353, is the definitive solution to restore full functionality and reliability to your vehicle’s systems.
We take the guesswork out of the repair. Unlike a generic module from a dealership or salvage yard, this BCM arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This eliminates the need for expensive programming tools or a trip to the dealer for software installation. Simply provide your VIN during checkout, and we handle the rest, ensuring a seamless installation process.
We had a 2008 SRX in the shop that was driving the owner crazy. The dome lights would randomly stay on, the driver’s power window worked intermittently, and the security light would flash for no reason. We checked grounds, wiring, and switches, but everything tested fine. The culprit was a failing BCM that was sending corrupt data across the network. Swapping in a VIN-programmed module like this one solved every single issue in under an hour. It’s often the hidden cause of the most confusing electrical gremlins.
Common Symptoms of a Failing BCM
- ✔️ Erratic or non-functional interior and exterior lights.
- ✔️ Power windows, door locks, or mirrors operating incorrectly or not at all.
- ✔️ Malfunctioning climate control system.
- ✔️ Security system faults or vehicle refusing to start.
- ✔️ False warnings on the instrument cluster (e.g., ‘Service Theft System’).
- ✔️ Unresponsive key fob or remote start functions.
- ✔️ Intermittent issues that are impossible to replicate consistently.

These procedures are straightforward and detailed in the post-installation notes.
Post-Installation Requirements
After installing your new BCM, certain systems may need to be re-synchronized with the vehicle. This is a normal part of the process.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light is on.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the BCM do on my 2007-2009 Cadillac SRX?
The Body Control Module (BCM) acts as the main computer for your vehicle’s comfort and convenience features. It controls the power windows, locks, lights, security system, climate control, and more, ensuring everything works as it should.
Is this BCM truly plug-and-play?
Yes, for the most part. We pre-program it to your vehicle’s VIN, which handles the most complex part of the installation. In some cases, simple ‘relearn’ procedures may be needed for specific subsystems like the airbag or brake sensor, which can often be done with a high-end scan tool.
How do I provide my VIN for programming?
You can add your vehicle’s 17-digit VIN to the notes section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we program and ship the module.
Will this fix my specific electrical problem?
This BCM is the correct part to fix issues caused by a faulty module. If your vehicle exhibits the common symptoms listed, there is a very high probability this will resolve them. However, we always recommend a proper diagnosis to confirm the BCM is the root cause before ordering.
Do I need to send my old BCM back?
No. This part is sold without a core charge. You can keep your original module.
