Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical issues in your vehicle? Flickering lights, malfunctioning power windows, a temperamental security system, or dashboard warning lights that have a mind of their own are all classic signs of a failing Body Control Module (BCM). As the central command center for your car’s body electronics, a faulty BCM can cause widespread and frustrating problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. Getting this fixed correctly is paramount.
We offer a straightforward and reliable solution: a replacement BCM programmed with your vehicle’s exact data. This isn’t just a part in a box; it’s a comprehensive service designed to get you back on the road without the exorbitant costs and scheduling headaches of a dealership visit. By cloning the information from your original BCM directly onto this replacement unit, we ensure it’s a true plug-and-play component. This process preserves your vehicle’s specific settings, including key programming and VIN data, making the installation process as simple as possible for the DIY mechanic or professional technician.
From the Diagnostic Bay: The Case of the Confused Volt
A few months back, a 2012 Chevy Volt was towed into my shop with a laundry list of complaints. The owner reported the radio would turn on and off randomly, the driver’s side window wouldn’t respond, and worst of all, the car would intermittently refuse to ‘power on’ after being parked. A scan revealed a storm of communication error codes (U-codes) between various modules. My first instinct was to check the 12V battery, which was fine. After tracing the communication network, all signs pointed to the BCM. Instead of a new, unprogrammed module from the dealer which would have required hours of setup, we used a cloned unit. The customer shipped us their faulty BCM, we performed our data transfer service, and sent back the ready-to-install replacement. The result? All electrical gremlins vanished. It’s a perfect example of how a correctly programmed 2012 Volt Body Control Module can solve a complex-seeming problem efficiently.
Common Symptoms of a Failing GM BCM
If your vehicle is experiencing any of the following, a failing BCM could be the culprit. I’ve seen these issues countless times in my 20+ years of diagnostic work. Look out for:
- ✔ Erratic or non-functional interior and exterior lighting.
- ✔ Power windows, locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ Unexplained battery drain while the vehicle is parked.
- ✔ Warning lights on the dashboard, such as the airbag or ABS light.
- ✔ Communication failure codes (e.g., U0140 – Lost Communication With Body Control Module).
- ✔ The vehicle failing to start or enter the ‘ready’ state.
Your Step-by-Step BCM Installation Guide
Installing your pre-programmed 2012 Volt Body Control Module is a manageable job for someone with basic mechanical skills. The location varies by model (see fitment list), but the general process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the 2012 Volt, the BCM is located in the right-hand side of the engine compartment. For other models, it may be under the dash or behind a kick panel. Consult your service manual for the exact location.
- 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 secure it. Reconnect all electrical connectors, making sure they click firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, windows, locks, etc. Note any warning lights that may appear and refer to the post-installation procedures below.
Important Post-Installation Information
While our programming service makes this a near plug-and-play repair, some GM vehicles may require additional sync procedures:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary for proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the cloning service work?
You purchase this listing and then ship your original BCM to us. We use specialized equipment to read the unique programming, VIN, and security data from your module and write it onto the replacement unit. We then ship the fully programmed module back to you, ready for installation.
What if my original BCM is too damaged to be read?
In most cases, even with significant internal failure, we can still retrieve the necessary data. If your module is physically destroyed (e.g., shattered, fire/water damage), please contact us before ordering to discuss options.
Do I need any special tools for installation?
For the physical installation, you’ll typically only need basic hand tools like a socket set or screwdriver to access and remove the module. However, as noted, a professional diagnostic scan tool may be required for post-installation procedures like the airbag system sync if the warning light appears.
Is this part number 13583542 compatible with other numbers?
Yes. This module is a direct, compatible replacement for several part numbers, including 13580696, 123589093, 13588446, and 13584692. Our service ensures it will function correctly in any vehicle on the fitment list.
Why is my airbag light on after installing the BCM?
This is a common security feature in GM vehicles. The new BCM and the airbag system’s Sensing and Diagnostic Module (SDM) need to be electronically ‘introduced’. This requires a ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool to turn off the light.
Do I have to send my old part back?
Yes, you must send us your original BCM so we can clone its data. However, there is no core charge or deposit, and we ship your original module back to you along with the programmed replacement.
