Tired of Bizarre Electrical Issues in Your Cadillac SRX?
If you’re dealing with flickering lights, power windows with a mind of their own, a security system that prevents your car from starting, or random warning messages on your dash, you’re not alone. As a technician with over two decades of experience, I’ve seen these exact issues hundreds of time, and the culprit is almost always a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s comfort and convenience features. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated electrical problems.
Forget the expensive trip to the dealership and the hassle of programming a new module from scratch. This is a professionally prepared Body Control Module, compatible with part number 13574844, for your 2010 SRX BCM. We make the process simple with our mail-in cloning service. You send us your original BCM, and we transfer all of its critical data—including VIN, mileage, and key information—to this replacement unit. The result? A true plug-and-play solution that gets you back on the road without any additional programming fees.
From the Diagnostic Bay: The Case of the Haunted Cadillac
A customer brought in a 2010 SRX with a laundry list of complaints: the radio would randomly shut off, the dome lights would stay on, and occasionally, it wouldn’t start, showing a ‘Service Theft Deterrent System’ message. They had already replaced the battery to no avail. After connecting my scan tool, I saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of quoting them over a thousand dollars for a new module and dealer programming, we suggested a cloning service. By transferring the data from their failing BCM to a quality replacement, we solved every single issue in one go. The customer saved hundreds and avoided days of vehicle downtime. This is the power of a properly prepared module.
Common Signs of a Failing 2010 SRX BCM
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Problems with the keyless entry or remote start system.
- ✔ Warning lights on the dashboard, such as for the security or airbag systems.
- ✔ Communication error codes like U0140 (Lost Communication With Body Control Module).
- ✔ The vehicle’s theft-deterrent system activating incorrectly, causing a no-start condition.
Your Straightforward BCM Installation Guide
Installing your cloned 2010 SRX BCM is a direct swap. Here’s a general guide to get the job done:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: In the 2010 Cadillac SRX, the Body Control Module is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the BCM.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, windows, locks, and start the vehicle.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is done with a professional-grade scan tool and syncs the airbag system to the BCM.
- 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 qualified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
How does the mail-in cloning service work?
After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will transfer the data to the replacement module and ship it back to you, usually within 1-2 business days. You’ll receive tracking information once it’s on its way.
Is this really plug-and-play?
Yes! Because we clone your vehicle’s original data, the replacement BCM will be recognized by your car’s other computers. This eliminates the need for expensive programming at a dealership.
Do I need to send my keys with the BCM?
No, we do not need your keys. All the necessary security information is stored within the BCM itself, and our process transfers it directly to the new module.
What happens if my airbag light comes on after installation?
This is a known possibility. The airbag module (SDM) may need to be electronically re-synced with the new BCM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by most repair shops with a professional scan tool.
Is there a core charge?
No, there is no core charge for this part. You are free to keep your original module after our cloning service is complete.
