Restore Your Cadillac’s Electrical System and Drive with Confidence
Are you dealing with baffling electrical issues in your 2012 Cadillac SRX? Maybe the power windows have a mind of their own, the interior lights flicker, or the vehicle refuses to start intermittently. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s comfort and convenience features. Driving with a faulty BCM isn’t just annoying—it can be a serious inconvenience. This replacement 2012 SRX Body Control Module, part number 13580696, is the definitive solution to get your vehicle back to perfect working order without the exorbitant costs and scheduling headaches of a dealership visit.
We specialize in providing a seamless, plug-and-play fix. How do we do it? Through our professional cloning service. Simply purchase this module, and we’ll contact you with instructions to send us your original BCM. Once it arrives, our technicians will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. We then ship the programmed module back to you, ready for immediate installation. This process completely bypasses the need for expensive on-vehicle programming with a specialized scan tool.
A Technician’s Notebook: The Ghost in the SRX
A customer brought in a 2012 SRX with a list of complaints that sounded like the car was haunted. The radio would turn on by itself, the driver’s side door wouldn’t unlock with the fob, and the security light was always on. They’d already replaced the battery, but the problems persisted. After connecting my diagnostic tool, I saw a slew of communication error codes (U-codes) pointing to the BCM. Instead of a deep electrical short, the BCM itself was failing internally, corrupting the data network. By installing a cloned BCM, we restored all functions in under an hour. The customer saved hundreds compared to the dealership quote and drove away with a perfectly functioning car. This is a repair I’ve seen dozens of times on these GM platforms.
Common Signs of a Failing BCM
- âś” Erratic or non-functional power windows, door locks, and interior/exterior lights.
- âś” The security or anti-theft system light stays illuminated, potentially causing a no-start condition.
- âś” Horn honking unexpectedly or not working at all.
- âś” Dashboard warning lights appearing for no reason.
- âś” Communication failure codes (like U0140) stored in other modules, pointing to a loss of communication with the BCM.
- âś” Wipers or climate control operating incorrectly.
Your Straightforward Installation Guide
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- âś” Locate the BCM: In the 2012 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.
- âś” Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. Note their orientation. Then, unbolt the module from its mounting bracket.
- âś” Install the New Module: Mount your newly programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- âś” Reconnect Power: Reattach the negative battery terminal.
- âś” Test All Functions: Start the vehicle and thoroughly test all body-related functions: lights, locks, windows, wipers, radio, etc., to confirm the repair.
Important Post-Installation Information
While our cloning service makes this a true plug-and-play solution, some vehicle systems may require a quick sync-up procedure after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed. This requires a professional-grade diagnostic tool to re-establish communication between the BCM and the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will email you detailed instructions and a shipping address. You mail your original BCM to us. We then transfer all of its essential data to the replacement module and ship it back to you, usually within 1-2 business days of receiving yours.
Is this really plug-and-play?
Yes! Because we clone your original module’s data, the replacement BCM is ready for installation right out of the box. This eliminates the need for a trip to the dealership for expensive programming.
Do I need to return my old BCM as a core?
No, there is no core charge. After we clone the data, you can keep your original module. We only need it for the initial data transfer service.
What tools do I need for installation?
Basic hand tools are usually all that’s required, such as a socket set and a panel removal tool to access the BCM’s location in the dash.
What if my original BCM is completely dead and unreadable?
In the rare event that your module’s data is corrupted beyond recovery, we will contact you to discuss alternative solutions. However, in over 98% of cases, we can successfully retrieve the necessary data.
Will this fix my specific problem?
This module corrects issues directly caused by a faulty BCM. If your vehicle has been properly diagnosed with a failed BCM, this part is the solution. It will not fix problems related to other components, such as a bad switch or wiring short.
