Restore Your Cadillac’s Brain and End Electrical Chaos
If you’re dealing with a 2011-2012 Cadillac SRX that seems to have a mind of its own—windows not working, dashboard lights flashing randomly, or a security system that prevents it from starting—you’ve likely met the frustrating reality of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause a cascade of bewildering issues. I’ve spent years in the shop tracing these gremlins back to this single component. The good news is, you’ve found the straightforward, cost-effective solution that bypasses an expensive trip to the dealership.
This isn’t just a replacement part; it’s a complete service. We provide a fully functional BCM, part number 13501737 (and its interchanges), that is professionally programmed with your vehicle’s specific data. The process is simple: you send us your original BCM, and we transfer all the critical information—like your VIN and key security data—to this replacement unit. We then ship it back to you, ready for a plug-and-play installation. This cloning service ensures seamless integration, preserving all original functions without the need for dealer-level diagnostic tools for programming.
A Technician’s Notebook: The SRX That Wouldn’t Cooperate
A customer brought in a 2011 SRX with a laundry list of complaints: the radio would shut off, the power liftgate was inoperative, and the car would intermittently fail to start, showing a “Service Theft Deterrent System” message. They had already replaced the battery to no avail. My initial scan showed a flurry of U-codes, indicating communication loss between various modules. This is a classic sign of a BCM failure. Instead of just talking to other modules, it was creating network-wide static. By isolating the BCM, the network stabilized. We performed our cloning service onto a replacement module, and upon reinstallation, every single issue was resolved. It’s a testament to how critical a healthy 2011-2012 SRX BCM is to the vehicle’s entire operation.
Common Signs of a Failing BCM
A failing BCM can manifest in numerous ways. If your vehicle is experiencing any of the following, this programmed module is your solution:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Problems with the climate control or radio system.
- ✔ Communication error codes (U-codes) like U0100, U0140, or U0155 stored in other modules.
- ✔ Inconsistent operation of exterior lights, including headlights or turn signals.
Your Straightforward BCM Installation Guide
Installing your pre-programmed 2011-2012 SRX BCM is a manageable task for a DIY enthusiast. For the 2011-2012 SRX, the BCM is typically located behind the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On the SRX, you will need to access the area to the left of the steering column, often behind the lower dash panel. Consult a vehicle-specific guide for panel removal instructions.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical harnesses. Ensure each connector clicks firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Post-Installation Checks: Turn the key to the ‘On’ position (without starting) and check for normal function of lights, locks, and windows. Start the vehicle. Note: Some models may require the additional procedures listed below.
Important Post-Installation Notes
While our programming handles the core functions, some vehicle systems may require a handshake with the new BCM. Be aware of these potential, but not always necessary, steps:
- Airbag System Sync: If your airbag light is on 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 relearn may be required to ensure proper brake light and stability control operation. This also typically requires a capable scan tool.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the vehicle-specific data and transfer it to the replacement module. We then ship the newly programmed module back to you, typically within 1-2 business days.
Do I need to take my car to the dealer after installation?
No. Our cloning service makes this a plug-and-play solution. Because we transfer your vehicle’s original data, the car will recognize the module as its own, eliminating the need for expensive dealership programming.
What is a core charge? Do I have to send my old part back?
There is no core charge for this item. We require your original module to perform the programming service, after which we ship the replacement to you. You can keep your old, non-functional module.
Is this BCM compatible with other part numbers?
Yes, this module is a direct replacement for a wide range of part numbers, including 13501737, 13583450, 13579004, and many others listed in the description. Please check the list to confirm compatibility.
What if my airbag light comes on after I install it?
This is a possibility. The new BCM needs to be electronically introduced to the airbag control module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. Any competent repair shop can perform this sync for you.
