Restore Your Vehicle’s Electrical Harmony
If your 2012 Cadillac SRX is experiencing a baffling array of electrical issues—from flickering lights and erratic power windows to a complete no-start condition—the culprit is often the Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a failing BCM can turn a reliable vehicle into a source of daily frustration. It’s the central command center for your car’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can affect safety systems and leave you stranded. We offer a straightforward, reliable solution to get you back on the road without the exorbitant costs and scheduling headaches of a dealership visit.
Our service provides a fully programmed replacement BCM that is a direct fit for part numbers including 13588446 and 13580696. The process is simple: you purchase this service, ship your original BCM to our facility, and we handle the rest. We will meticulously transfer all the critical vehicle-specific data from your original module to this replacement unit. This cloning service ensures that when you receive the BCM back, it’s truly plug-and-play, preserving your vehicle’s key codes, security information, and specific options. This is the most efficient way to replace a faulty 2012 SRX BCM.
A Technician’s Notebook
Just last month, a 2012 Chevy Equinox (which uses this same BCM family) was towed into the shop. The customer was frustrated, explaining that the dash lights would flicker randomly, the radio would cut out, and sometimes the key fob wouldn’t work at all. They had already replaced the battery to no avail. After running diagnostics, we found communication errors pointing directly to the BCM. Instead of quoting them over a thousand dollars for a new module and programming at the dealer, we recommended this cloning service. We had the original module cloned, installed the replacement, and the Equinox was back to perfect working order in a fraction of the time and at a fraction of the cost. The customer was thrilled to have their reliable vehicle back without breaking the bank.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system light is flashing, preventing the engine from starting.
- ✔ Horn honking unexpectedly or the alarm going off randomly.
- ✔ Dashboard warning lights (like ABS or Airbag) are illuminated for no apparent reason.
- ✔ Communication error codes stored, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers or turn signals functioning intermittently.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2012 SRX, the BCM is typically located on the left-hand (driver’s) side of the dashboard. In other compatible models, it may be in the LH kick panel or under the center dash. Consult a service manual for your specific vehicle’s location.
- ✔ Remove the Original BCM: Carefully disconnect all electrical connectors from the module. They have locking tabs that must be depressed to be removed. Unbolt or unclip the module from its mounting bracket.
- ✔ Install the Replacement: Mount your newly programmed BCM in the same location. Reconnect all electrical connectors firmly, ensuring each one clicks into place.
- ✔ Reconnect the Battery: Re-attach the negative battery terminal and tighten it securely.
- ✔ Perform Post-Install Checks: Start the vehicle and verify that all body functions (lights, locks, windows, etc.) are working correctly. Note the potential post-installation procedures below.
Important Post-Installation Information
While our programming service makes this a plug-and-play repair, some vehicle systems may require a recalibration or sync procedure after the BCM is installed. This is normal and depends on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is on 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: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Once we receive it, we transfer all of its data to the replacement unit and ship it back to you, typically within one business day.
Is this BCM truly plug-and-play?
Yes. Because we clone the data from your original module, the replacement BCM will be ready for installation without any additional programming or trips to the dealer. Your keys and vehicle options will work just as they did before.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and we will transfer it during the cloning process.
What if my original BCM is not communicating?
Even if your BCM has failed, in most cases we can still extract the necessary data for the cloning service. Please contact us with your specific symptoms if you have concerns about your module’s condition.
Is there a core charge for my old part?
No, there is no core charge. You are required to send your original BCM to us for the programming service, but you do not need to worry about any additional core fees.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional diagnostic scan tool. Many independent repair shops have this equipment if you are not able to perform the procedures yourself.
