Restore Full Electrical Function to Your Cadillac SRX
Is your 2007-2009 Cadillac SRX suffering from bizarre and frustrating electrical problems? From flickering lights and malfunctioning power windows to intermittent starting issues, a failing Body Control Module (BCM) can wreak havoc on your vehicle’s systems. The BCM acts as the central command center for your car’s body electronics, and when it begins to fail, the symptoms can be unpredictable and widespread. This replacement Body Control Module, part number 20864767, is the definitive solution to restore your vehicle’s functionality and peace of mind.
We take the guesswork and hassle out of the repair process. Unlike a generic part from a local store, this BCM is professionally programmed specifically for your vehicle using your VIN. This crucial step ensures that the module communicates flawlessly with all other computers in your SRX, retaining all original features and options. We install the latest GM-certified software updates, often correcting factory flaws and improving performance beyond the original state. This is a direct-fit, plug-and-play solution designed to get you back on the road quickly and reliably.
From the Diagnostic Bay
We recently had a 2008 SRX in the shop with a laundry list of strange issues. The customer reported that the radio would randomly turn off, the driver’s side power window wouldn’t work, and occasionally the security light would flash, preventing the car from starting. They had already replaced the battery and checked fuses with no luck. A scan tool showed multiple communication loss codes with various modules. Instead of chasing individual components, we focused on the common link: the BCM. After installing a VIN-programmed module just like this one, every single issue was resolved instantly. It’s a powerful reminder of how this single component is the key to dozens of vehicle functions.
Common Symptoms of a Failing 2007-2009 SRX BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, there’s a strong chance your Body Control Module is the culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (lights staying on, flickering, or not working at all).
- ✔ Malfunctioning dashboard gauges or warning lights (like the airbag or security light).
- ✔ Key fob not working correctly or vehicle security system acting up.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Communication errors (U-codes) when scanning the vehicle with a diagnostic tool.
- ✔ A no-start condition where the engine cranks but won’t fire up due to a security system fault.
The Plug-and-Play Advantage: Why VIN Programming is Essential
Installing a used or non-programmed BCM into your Cadillac SRX is a recipe for disaster. Modern vehicles use complex, interconnected networks of computers that must recognize each other to function. Our VIN programming service syncs this replacement module to your vehicle’s exact specifications. This means no expensive trips to the dealership for coding or flashing. You receive a part that is ready for installation right out of the box. Simply provide your VIN after purchase, and our technicians will handle the rest, ensuring a seamless and correct repair.
Installation and Post-Install Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems are properly synchronized after the new BCM is connected. These are known as relearn procedures.
- Airbag System Sync: In some cases, the new BCM may need to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: To ensure proper function of the brake lights and stability control systems, a brake pedal position sensor relearn might be required. This recalibrates the sensor to the new module.
Please Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module do on my Cadillac SRX?
The BCM is a computer that manages and controls most of the non-engine related electronic functions in your vehicle. This includes power windows, door locks, interior and exterior lights, the security system, climate controls, and the radio. It acts as a central hub, receiving input from switches and sensors and sending commands to the appropriate components.
Is this BCM truly plug-and-play?
Yes, for most functions. Because we program it to your vehicle’s VIN before shipping, it will be recognized by your vehicle’s other computers upon installation. This eliminates the need for dealership programming. However, as noted, some vehicles may require minor relearn procedures for systems like the airbag or brake pedal sensor to fully sync with the new module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
What happens if I don’t perform the post-installation procedures?
If a relearn procedure is required and not performed, you may have a persistent warning light (like the airbag light) or a system that doesn’t function correctly (like traction control). These procedures are essential for ensuring all vehicle systems are calibrated and communicating properly with the new BCM.
Will this fix my specific electrical problem?
While this BCM is the solution for a wide array of electrical issues listed in the symptoms section, vehicle diagnostics can be complex. We recommend confirming the BCM is the source of the fault through proper diagnosis by a qualified technician. A faulty BCM is a very common failure point for these symptoms on the 2007-2009 SRX BCM and related models.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module without any additional fees or hassle.
