Restore Your Vehicle’s Brain without the Dealership Headache
If you’re dealing with baffling electrical issues in your 2012 Cadillac SRX—like flickering lights, unresponsive power windows, or random warning messages—the Body Control Module (BCM) is often the culprit. As the central command center for your vehicle’s comfort and convenience features, a failing BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect vehicle security and safety systems. We offer a reliable, straightforward solution with this professionally programmed BCM, designed to get you back on the road quickly and affordably.
This is a complete programming service. Instead of shipping you a blank module that requires expensive dealership tools, we transfer the critical data from your original BCM to this replacement unit. The process is simple: after your purchase, you’ll ship your original module to us. We’ll perform a full data clone to this replacement BCM (part number 13580696), ensuring it’s a true plug-and-play solution for your 2012 SRX BCM. This preserves your vehicle’s specific settings, including key fob programming and security information, eliminating the need for costly post-installation programming.
Case Study: A Tricky Diagnosis
A customer brought in a 2012 SRX with a classic ‘haunted car’ scenario. The interior lights would pulse, the radio would randomly shut off, and the ‘Service Theft System’ message appeared intermittently. Scans showed a slew of communication loss codes (U-codes) with no clear pattern. After verifying the main power and ground circuits to the BCM were solid, we knew we were looking at an internal failure. In my 20+ years, I’ve seen hundreds of these BCMs fail due to heat cycles and vibration causing micro-fractures on the circuit board. Swapping in one of our pre-programmed modules resolved all issues in under 30 minutes, saving the customer hundreds compared to the dealership’s quote.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, or the vehicle not recognizing the key fob.
- ✔ A ‘no-start’ condition where the starter doesn’t engage.
- ✔ Multiple communication error codes, such as U0140, U0155, or U0100, stored in other modules.
- ✔ Inconsistent operation of the heating and A/C blower motor.
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 SRX, the BCM is typically located behind the left-hand (driver’s side) of the dashboard. Access may require removing the lower dash panel.
- ✔ 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 securing the module and take it out.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Test Functionality: Start the vehicle and test all related functions: lights, locks, windows, radio, and wipers to confirm the repair was successful.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require additional steps for full system harmony. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to do any programming myself?
No. This is a full programming service. We clone the data from your original BCM to the replacement unit, so it arrives ready to install without any need for dealer tools or software.
What is the process for the cloning service?
After you place your order, we will contact you with instructions for shipping your original BCM to our facility. Once we receive it, we will transfer the data to the new module and ship it back to you, typically within 1-2 business days.
Will this fix my specific problem?
This module resolves issues directly caused by a failing BCM, such as erratic lights, lock, and window operation, and certain no-start conditions. Proper diagnosis is key. If you are seeing multiple communication codes (U-codes), it’s a strong indicator the BCM is the fault.
What if my original BCM is completely dead or missing?
If your original module is non-communicative or lost, we may not be able to retrieve the necessary data for cloning. Please contact us before ordering to discuss potential options for your specific situation.
Do I need to send in my keys?
No, you do not need to send your keys. Because we are cloning your original module’s information, the replacement BCM will already recognize your existing keys upon installation.
Is there a core charge?
There is no core charge for this service. You are welcome to keep your original module after sending it in for data transfer.
