Restore Full Electrical Function to Your Vehicle
Is your 2007-2009 Cadillac SRX suffering from baffling electrical problems? Issues like malfunctioning power windows, erratic door locks, flickering interior lights, or a security system that won’t behave are often signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and seemingly unrelated symptoms. This isn’t just an inconvenience; it can affect the safety and security of your vehicle.
We offer a straightforward and reliable solution: a genuine GM Body Control Module, part number 15872388, pre-programmed specifically for your vehicle. Forget expensive dealership visits and the hassle of finding a shop with the right programming tools. We handle the complex part for you. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software updates and your vehicle’s exact configuration. The result is a part that arrives at your door ready for installation.
From the Diagnostic Bay
We had a 2008 Acadia (which uses this same BCM) come into the shop with the customer complaining of the radio turning on and off by itself and the power locks acting possessed. They had already replaced the battery and checked the alternator. Initial scans pointed towards the BCM, but before ordering a new one, we did a full systems check. We found a corroded ground wire under the driver’s side kick panel. After cleaning the connection and tightening it down, all the symptoms vanished. This is a crucial reminder: always check your main power and ground connections before condemning an expensive module. A simple fix can sometimes save you hundreds of dollars.
Is Your Vehicle Showing Signs of a Bad BCM?
A failing Body Control Module can manifest in numerous ways. If you’re experiencing several of the following issues, a faulty BCM is the likely culprit:
- ✔ Power windows or locks operating intermittently or not at all.
- ✔ Interior dome lights, dash lights, or headlights flickering or staying on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers behaving erratically (e.g., won’t turn off).
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar” light).
- ✔ Communication errors with other vehicle modules, leading to various warning lights.
The Superior Solution: A Pre-Programmed 2007-2009 SRX BCM
Replacing a modern vehicle computer isn’t like swapping out a simple mechanical part. The BCM must be electronically matched to your car’s specific options and security system. Our service eliminates this barrier. By programming the module to your VIN before shipment, we ensure it communicates seamlessly with your vehicle’s other computers, like the Engine Control Module (ECM) and Transmission Control Module (TCM). This 2007-2009 SRX BCM is a direct-fit replacement for a wide range of original equipment part numbers, ensuring broad compatibility across many GM models including the Equinox, Impala, Acadia, Traverse, and more. Please verify your part number against our extensive cross-reference list to confirm fitment.
Installation and Post-Install Considerations
While this module is sent ready for installation, some vehicles may require minor post-installation procedures, often called “relearns.” These can typically be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This requires a ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure correct brake light and traction control operation.
These procedures are not always required but are important to be aware of. Always consult a factory service manual for your specific vehicle for detailed instructions.
Frequently Asked Questions
What does a Body Control Module actually do?
The BCM is a computer that manages and controls many of the non-engine-related electronic functions in your vehicle. This includes power windows, power mirrors, air conditioning, interior and exterior lighting, power locks, keyless entry, and the anti-theft system. It acts as a central hub for these convenience and security features.
Is this BCM difficult to install?
The physical installation is typically straightforward. On the 2007-2009 SRX, the BCM is located on the left-hand (driver’s) side of the dash. It involves removing a few trim panels and disconnecting electrical connectors. The main benefit of our service is that the complex software programming is already done, saving you a trip to the dealership and making the process much simpler.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
What information do you need to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to access the correct software and vehicle-specific options from GM’s database to program the module perfectly for your car before we ship it.
Will this fix my vehicle’s battery drain issue?
A faulty BCM is a common cause of parasitic battery drain. If the module fails to go into “sleep mode” after the car is turned off, it can continue to draw power and drain the battery overnight. Replacing a faulty BCM can often resolve these types of electrical draws.
