Restore Your Vehicle’s Brain and End Electrical Gremlins for Good
Are you battling a car that seems to have a mind of its own? Flickering lights, power windows that won’t cooperate, a radio that acts possessed, or even a no-start condition can all point to one culprit: a failing Body Control Module (BCM). As the central hub for your vehicle’s electronics, a faulty BCM can cause widespread, frustrating issues. This isn’t just an annoyance; it’s a breakdown in your car’s nervous system. Our plug-and-play solution, centered around this replacement BCM for part numbers like 13580696 and 13588446, is the most reliable and cost-effective way to get back on the road without the exorbitant costs and scheduling hassles of a dealership visit.
We’ve engineered a seamless process. Instead of you needing an expensive diagnostic tool for programming, we handle all the technical work. Simply purchase this service, and we’ll contact you with instructions to ship your original BCM to our facility. Our expert technicians will then perform a full data transfer, or ‘cloning,’ from your old module to this fully tested replacement. This ensures all your vehicle’s specific settings, key data, and security information are perfectly preserved. The result is a true plug-and-play 2012 Regal BCM that is ready for installation right out of the box.
Case Study: A Tricky Diagnosis
A few months back, a 2013 LaCrosse was brought to my shop with a maddeningly intermittent no-start condition. The owner had already replaced the battery and checked the starter. The dashboard would light up, but turning the key did nothing. When it did start, the security light would sometimes flash, and the passenger window wouldn’t respond. After hooking up the scan tool, I saw a slew of communication error codes (U-codes) pointing to a network failure. Instead of chasing ghosts, experience told me to look at the network’s traffic controller: the BCM. A faulty BCM can disrupt the entire CAN bus system, causing exactly these kinds of phantom problems. By installing a BCM cloned from the original, we restored perfect communication between all modules, solving every single issue in one go. This is the power of a correctly programmed module.
Common Signs of a Failing GM BCM
- ✔ Unpredictable behavior from power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights appear randomly (e.g., Airbag, ABS, Traction Control).
- ✔ The horn honks unexpectedly or doesn’t work at all.
- ✔ Communication error codes, such as U0100, U0140, or other U-series DTCs, are stored in the system.
- ✔ Complete loss of power to multiple electronic accessories at once.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: The BCM’s location varies. On a 2012 Regal or SRX, it’s typically behind the left side of the dash. On a Camaro, it’s on the right side. For a Volt, check the engine compartment. Consult a service manual for your specific model’s location.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be pressed or lifted. Then, unbolt the module from its mounting bracket.
- ✔ Install the New BCM: Mount your newly programmed BCM in the same location and securely reconnect all electrical harnesses. Ensure they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- ✔ Verify Operation: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, certain vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, the brake pedal position sensor may need to be recalibrated to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific requirements can vary. Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
How does the mail-in cloning service work?
It’s simple! After your purchase, we will email you instructions and a shipping address. You mail your original BCM to us. We transfer its data to the replacement unit and ship it back to you, typically within 1-2 business days of receiving it.
Will I need to do any programming or visit a dealer?
No. Our cloning service makes the replacement BCM fully programmed for your vehicle’s VIN and options. It will be plug-and-play, eliminating the need for dealer programming.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we will transfer during the cloning process.
What happens if my airbag light comes on after I install it?
This is a known possibility. The airbag module (SDM) may need to be electronically re-synced to the new BCM. This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible bi-directional scan tool.
Is there a core charge for my old BCM?
No, there is no core charge. After we clone the data from your original module, you are welcome to keep it.
