Restore Full Functionality to Your Cadillac SRX
Are you dealing with baffling electrical issues in your 2011-2012 Cadillac SRX? Problems like flickering interior lights, power windows or locks that have a mind of their own, or warning messages that won’t go away are classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can turn your luxury SUV into a source of daily frustration. This isn’t just an inconvenience; it can affect vehicle security and safety systems. In my 20+ years of experience, I’ve seen how a bad BCM can mimic a dozen other problems, leading to expensive and incorrect repairs.
We offer a straightforward, reliable solution. This is a comprehensive cloning service for a replacement BCM compatible with part number 13579004. You simply ship us your original module, and we transfer all of its critical data—including VIN, mileage, and security information—to a fully tested replacement unit. We then ship the programmed module back to you, ready for a true plug-and-play installation. This process eliminates the need for a costly trip to the dealership for programming, saving you time and hundreds of dollars.
Common Signs of a Failing BCM
If your SRX is exhibiting any of these symptoms, a failing BCM is the likely culprit. A failing module can also trigger various communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights behaving erratically or not working at all.
- ✔ The security system engaging randomly or preventing the car from starting.
- ✔ Inaccurate gauge readings or a completely dead instrument cluster.
- ✔ Warning lights on the dash, including ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
A Technician’s Notebook: The Ghost in the SRX
A customer brought in a 2011 Cadillac SRX with a truly bizarre set of problems. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the anti-theft light would flash randomly, sometimes preventing it from starting. They had already replaced the battery and alternator with no luck. After connecting my diagnostic tool, I saw a flood of U-codes, indicating a massive communication breakdown between modules. This is a tell-tale sign. Instead of chasing individual components, I went straight for the BCM. After swapping in a known-good module, every single ghost-like issue vanished. This is a perfect example of how a single failing 2011-2012 SRX BCM can create widespread, confusing symptoms.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. After you receive your programmed module from us, follow these steps. The BCM in the 2011-2012 SRX is typically located on the left (driver’s) side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: Access the BCM by removing the necessary trim panels on the driver’s side of the dash, near the kick panel area.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Post-Installation Checks: Start the vehicle and verify that the original issues are resolved. Check the function of windows, locks, lights, and the instrument cluster. See the Post-Installation Procedures section below for potential additional steps.

Important Post-Installation Procedures
While our service makes this a plug-and-play repair, some vehicle systems may require a relearn or sync procedure after the BCM is replaced. These are standard procedures for this type of repair.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper operation of the brake lights and traction control system.
- Disclaimer: Procedures can vary. For detailed instructions specific to your vehicle, always consult a factory service manual or a certified automotive technician.
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique programming and security data and flash it onto your new replacement module. We then ship the ready-to-install BCM back to you.
Do I need to get this programmed at the dealer?
No. The entire purpose of our service is to handle the programming for you. The module you receive will be pre-programmed with your vehicle’s specific data, making it a plug-and-play installation and saving you from expensive dealer fees.
Is this a new or used part?
We provide a fully tested, guaranteed good used or refurbished BCM that has been programmed with your vehicle’s data. Every module passes a rigorous inspection to ensure it meets or exceeds OEM performance standards.
Is there a core charge?
No, there is no core charge for this service. We need your original module to perform the data cloning, but you do not need to send it back to us after you receive your replacement.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data from the memory chip. Please contact us with the details of your BCM’s failure, and our experts can advise on the likelihood of a successful data transfer.
How long does the service take?
Typically, we program and ship your replacement BCM within 1-2 business days of receiving your original module. We will provide you with a tracking number as soon as it ships.
