Restore Your Vehicle’s Electronic Stability
Are you dealing with baffling electrical issues in your 2012 Cadillac SRX? Problems like flickering interior lights, unresponsive power windows or door locks, a security system that acts up, or even a car that refuses to start can often be traced back to a single component: the Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, a failing BCM can create a cascade of frustrating and unpredictable symptoms. I’ve seen it hundreds of times in my shop—a perfectly good car rendered unreliable by a faulty module.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professionally programmed Body Control Module, part number 13580696, that is ready for installation upon arrival. Our unique cloning service eliminates the need for expensive dealership visits for programming. Simply send us your original BCM, and our expert technicians will transfer all the critical vehicle-specific data to this replacement unit. We handle all the technical work, so you get a true plug-and-play module that restores your car’s functionality right out of the box.
A Technician’s Notebook: The SRX with a Mind of Its Own
A customer brought in a 2012 SRX that was, in her words, ‘possessed.’ The radio would change stations on its own, the dome lights would stay on, and occasionally, the alarm would go off for no reason. Initial scans showed a flurry of communication error codes (U-codes), pointing fingers everywhere. Instead of just replacing parts, we focused on the network’s hub. By monitoring data streams from the original BCM, we saw intermittent signal dropouts that perfectly matched the owner’s complaints. A new, dealer-supplied BCM would have meant a tow and costly programming. Instead, we used our cloning service. By transferring the data from her original module to a quality replacement, we preserved all her key fob data and vehicle settings. The ‘possessed’ SRX was back to normal the same day, saving the customer time, money, and a huge headache. This is the power of a properly programmed 2012 SRX BCM.
Is Your Vehicle Showing These Symptoms?
- ✔ Unpredictable power window or door lock operation.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry system is malfunctioning.
- ✔ Intermittent no-start condition where the engine cranks but won’t fire up.
- ✔ Warning lights on the dash for systems like ABS, Airbag, or Traction Control.
- ✔ Communication error codes stored, such as U0140, U0155, or other related DTCs.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any work on the electrical system.
- ✔ Locate the BCM: In 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. Press the release tabs firmly to avoid damaging the connectors. 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 reconnect all electrical connectors. Ensure they click securely into place.
- ✔ Reconnect Battery: Reattach the negative battery terminal.
- ✔ Perform Post-Install Checks: Start the vehicle and test all body functions—windows, locks, lights, radio, etc. Note that some vehicles may require the additional procedures listed below.
Important Post-Installation Information
While our programming service makes this a plug-and-play repair, some GM vehicles may require simple relearn procedures after the BCM is replaced. These are standard procedures and do not indicate a fault with the module.
- Airbag System Sync: If the airbag warning light is illuminated 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: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

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. Our technicians will then extract the vehicle-specific data and flash it onto the replacement module. This ensures it works with your existing keys and vehicle options without any additional programming.
Do I need to send my original BCM?
Yes. To make this a true plug-and-play solution, we must clone the data from your original module. This is the only way to avoid a trip to the dealership for expensive programming.
What is the turnaround time?
We program and ship your replacement BCM within 1-2 business days of receiving your original module. We will send you a tracking number as soon as it ships.
Will this fix my specific problem?
This part corrects issues directly caused by a faulty BCM. If your vehicle exhibits symptoms like erratic lights, window/lock failures, or certain no-start conditions, a failing BCM is the most likely cause. A proper diagnosis is always recommended.
Is there a core charge for my old part?
No, there is no core charge. After we clone the data, you can keep your original module.
What if my airbag light comes on after installation?
This is a normal possibility on some GM vehicles. It simply means the new BCM needs to be synced with the airbag module using a ‘Setup SDM Primary Key’ procedure, which can be done with a professional-grade scan tool.
