Is Your Cadillac SRX Acting Possessed? The BCM Is Likely the Cause.
As a technician with over two decades of diagnostic experience, I’ve seen it all. When a vehicle, especially a sophisticated one like your 2012 Cadillac SRX, starts exhibiting a host of unrelated electrical issues, my mind immediately goes to the Body Control Module (BCM). This component is the central command center for your vehicle’s body electronics—power windows, locks, lighting, security system, and more. When it fails, it can feel like you’re chasing ghosts in the machine.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional cloning service for the 2012 SRX BCM, part number 13580696. You simply send us your original BCM, and we transfer all its critical data—including VIN, mileage, and key information—to this fully tested replacement unit. The module you receive back will be 100% plug-and-play, saving you from a costly trip to the dealership for programming and configuration.
A Technician’s Notebook: The Intermittent SRX Gremlin
I remember a 2012 SRX that came into the shop with a laundry list of complaints from the owner. The radio would turn off randomly, the driver’s side window wouldn’t go down, and occasionally, the security light would flash, preventing the car from starting. Scans showed a slew of communication errors (U-codes) pointing to multiple modules. A less experienced tech might have started replacing parts one by one. But the pattern screamed ‘central failure.’ We isolated the BCM, and after confirming its internal failure, a cloned replacement like this one had the vehicle functioning perfectly in under an hour. It’s a classic case where understanding the system saves hundreds in diagnostic time and parts.
Key Indicators of a Failing Body Control Module
- ✔ Power windows or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to turn on.
- ✔ The vehicle’s security system engaging randomly, causing a no-start condition.
- ✔ The horn honking unexpectedly or the panic alarm going off.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Theft System’).
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2012 Cadillac SRX, the BCM is typically located on the left-hand (driver’s) side of the dash. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place and take it out.
- ✔ Install the New Module: Seat your newly programmed BCM in the same location and secure it with the original hardware.
- ✔ Reconnect Everything: Plug the electrical connectors firmly into the new module. You will hear a click as they lock into place. Reconnect the negative battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to synchronize the systems and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any procedure.

After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. We then ship the fully programmed, plug-and-play module back to you, typically within 1-2 business days.
No. Because we are cloning all the data from your original module, the replacement unit will recognize your existing keys. This saves you the significant expense and hassle of having new keys programmed at a dealership.
In many cases, even if the BCM has failed and is not communicating with the vehicle, we can still extract the necessary data directly from the memory chip. Please contact us with your specific situation before ordering if you have concerns.
No, there is no core charge for this service. You are welcome to keep your original module after the programming service is complete.
