Is Your GM Vehicle Plagued by Baffling Electrical Issues?
If your Chevrolet Volt, Buick LaCrosse, or GMC Terrain is acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or even a no-start condition—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s electronic accessories. It manages everything from your interior lights and power locks to the security system and climate controls. When it begins to fail, it can create a cascade of frustrating and seemingly unrelated problems that can be a nightmare to diagnose.
Don’t let a faulty BCM keep you off the road or force you into an expensive and time-consuming visit to the dealership. We offer a simple, reliable, and cost-effective solution: a replacement BCM that is professionally programmed with the data from your original unit. This cloning service makes the replacement process truly plug-and-play, eliminating the need for complex on-vehicle programming or calibration tools.
From the Diagnostic Bay
We had a 2012 Chevy Cruze come into the shop with a laundry list of bizarre symptoms. The customer reported that the radio would turn on and off by itself, the turn signals worked intermittently, and sometimes the car wouldn’t recognize the key fob. They had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes across various systems, all pointing back to one central component. By monitoring the data stream from the BCM, we saw it was dropping communication intermittently. We installed one of our programmed BCMs, and instantly, all the ghost-like electrical issues vanished. It’s a classic case of how a single failing module can make an entire vehicle seem haywire.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The vehicle’s security system engaging randomly or preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights (like the airbag or ABS light) appearing on the dash for no reason.
- ✔ Complete no-start condition where the engine doesn’t crank.

- Place Your Order: Complete your purchase through our secure checkout.
- We’ll Contact You: Our team will reach out to you with clear, simple instructions and a shipping address. Please ensure your contact information is up to date.
- Ship Us Your Original BCM: Carefully remove your original BCM and send it to us.
- We Clone the Data: Once we receive your module, our expert technicians will transfer all the critical vehicle-specific data (including VIN, mileage, and key information) to the replacement unit.
- Receive Your Plug-and-Play Module: We ship the newly programmed BCM back to you. Installation is as simple as removing the old one and plugging in the new one. No further programming is required.
Why Choose Our Programmed 2013 Volt Body Control Module?
This isn’t just a replacement part; it’s a complete solution. By cloning your original module’s data, we ensure that the replacement BCM integrates seamlessly with your vehicle’s existing electronic systems. This method preserves your original key programming and vehicle settings, making the installation process as simple as possible. This specific 2013 Volt Body Control Module is also compatible with a wide range of other GM vehicles, making it a versatile fix for many models experiencing these common electrical failures.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a simple relearn procedure after the new BCM is installed.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the new BCM and the airbag system’s SDM (Sensing and Diagnostic Module). A technician with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
- Brake Pedal Position Relearn: To ensure proper brake light operation and stability control function, a brake pedal position sensor recalibration might be necessary. This is also a simple procedure that can be performed with a capable diagnostic tool.
Please consult a factory service manual or a qualified technician for specific guidance, as procedures can vary by vehicle.
Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer in your car that controls and monitors many of the non-engine-related electronic functions. This includes power windows, locks, lights, wipers, the security system, and more. It acts as a central hub for these body electronics.
Why is cloning my original BCM better than just buying a used one?
A standard used BCM is programmed to a different vehicle. When installed in your car, it won’t have your vehicle’s specific VIN, key data, or option configuration, leading to a no-start condition or malfunctioning features. Our cloning service transfers all this critical data, making the replacement a true plug-and-play part for your specific car.
Do I need to send my keys with my BCM?
No, you do not need to send us your keys. All the necessary immobilizer and key data is stored within your original BCM. We transfer this information directly to the replacement module, so your existing keys will work perfectly upon installation.
Is this part compatible with other vehicles besides the 2013 Volt?
Yes. This BCM, identified by part numbers like 13586278, 13583450, and others listed, fits a wide variety of GM vehicles from roughly 2011-2013, including the Buick LaCrosse, Cadillac SRX, Chevy Cruze, and GMC Terrain. Please check the part numbers in the description against your original module to confirm compatibility.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data for the cloning process. If your module has severe physical damage (e.g., from water or fire), please contact us before ordering to discuss options.
