Restore Your Vehicle’s Electrical System with a Perfectly Matched BCM
Are you dealing with baffling electrical issues in your 2010 Cadillac SRX? Problems like power windows with a mind of their own, intermittent starting, flickering dashboard lights, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your daily drive into a frustrating guessing game. This isn’t just an inconvenience; it can affect vehicle safety and security. We offer a straightforward, reliable solution with our professional cloning service for BCM part number 13578420.
From the Diagnostic Bay: The Case of the Chaotic Cadillac
I remember a 2010 SRX that rolled into my shop last fall. The owner was at his wit’s end. The horn would blare randomly, the interior lights would stay on, and the key fob worked only half the time. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a storm of communication errors (U-codes) pointing to the BCM. Instead of a costly new module and days of programming at the dealer, we used this exact cloning service. We transferred the data from his failing BCM to our replacement unit. He had his SRX back the next day, all gremlins gone. This process is the most efficient and reliable fix I’ve found for these specific BCM failures.
What Are the Signs of a Failing BCM?
A failing BCM can cause a wide range of symptoms that may seem unrelated. If your vehicle is experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic power windows, door locks, or mirrors that don’t respond correctly.
- ✔ Interior dome lights or exterior lamps staying on or not turning on at all.
- ✔ The anti-theft or security light is illuminated, preventing the engine from starting.
- ✔ Inconsistent or non-functional remote keyless entry (key fob).
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Communication error codes, particularly U-codes (e.g., U0140, U0155), stored in the system.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. Since we handle all the programming, you get a part that’s ready to install. No special tools are required for the swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the 2010 SRX and similar models, the BCM is typically found behind the driver’s side of the dashboard, near the kick panel. You may need to remove a lower dash panel for access.
- Swap the Modules: Carefully unplug the electrical connectors from your old BCM. Unbolt or unclip the module from its mounting bracket. Install the new, programmed module in its place and securely reconnect all electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all related functions—windows, locks, lights, and horn—to confirm the repair.
Important Post-Installation Information
While our service ensures the BCM is programmed to your vehicle’s specifications, some vehicle systems may require a quick sync-up after installation. Please be aware of the following:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
- Brake Pedal Position Relearn: Depending on your specific model and options, a brake pedal position sensor recalibration might be needed. This ensures your brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the BCM cloning service work?
It’s simple. After you place your order, we’ll provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to a fully functional replacement BCM. We then ship the programmed module back to you, ready for installation.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle is programmed with that vehicle’s VIN and options. It will not work in your car without being reprogrammed by a dealer, which is expensive and often not possible. Our cloning service ensures the replacement BCM is a perfect electronic match for your specific vehicle.
Where is the BCM located on my 2010 SRX?
The Body Control Module on a 2010 Cadillac SRX is located on the driver’s side, behind the lower part of the dashboard near the steering column.
Will I need to do any programming or visit a dealer?
No. The main benefit of our service is that we handle all the complex programming. The BCM you receive will be plug-and-play, saving you from a costly and time-consuming trip to the dealership.
What does ‘No Core Charge’ mean?
It means you don’t have to pay an extra deposit and you can keep your original module after you send it to us for the data transfer. There’s no need to ship it back a second time.
What if the airbag light is on after I install the BCM?
If the airbag light appears, it simply means the BCM and airbag module (SDM) need to be re-synced. This is a common security procedure that can be completed by any professional mechanic with a capable diagnostic tool using the ‘Setup SDM Primary Key in BCM’ function.
