Is Your Vehicle Experiencing Bizarre Electrical Issues?
If your Chevrolet Volt, Buick Regal, or GMC Terrain is suffering from flickering lights, malfunctioning power windows, erratic dashboard warnings, or other strange electrical gremlins, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, coordinating everything from your interior lights and door locks to your security system. When it fails, it can cause a cascade of frustrating and seemingly unrelated problems.
From the Diagnostic Bay
We had a 2012 Chevy Volt come into the shop with a complaint that was driving the owner crazy. The interior dome lights would randomly turn on while driving, the radio would shut off, and the key fob would only work intermittently. After checking all the usual suspects like fuses and wiring, our diagnostics pointed directly to an internal BCM failure. Instead of a costly trip to the dealer for a new module and programming, we used our cloning service. We transferred the data from his old, faulty BCM to a replacement unit. The customer was back on the road the next day with all issues resolved, saving him hundreds of dollars and significant downtime.
The Simple, No-Hassle Solution: A Pre-Programmed 2012 Volt BCM
Don’t let a faulty BCM keep you off the road. This replacement Body Control Module, compatible with part numbers including 13588446 and 13580696, is the definitive solution. We eliminate the need for expensive dealership programming by offering a straightforward mail-in cloning service. Simply purchase this BCM, send us your original module, and we’ll professionally transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. When you receive it back, it’s a true plug-and-play installation.
Common Symptoms of a Failing BCM:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’ light).
- ✔ Key fob recognition problems or security system malfunctions.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Wipers or climate control systems operating incorrectly.

Installation and Post-Install Procedures
Installation is as simple as disconnecting the battery, removing the old BCM, and plugging in the new one. However, in some vehicles, additional synchronization steps may be required.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How does the programming service work?
After you place your order, you will ship your original BCM to us. We then extract the vehicle-specific data from it and flash it onto the replacement module. This makes the new part a perfect electronic match for your car, avoiding the need for dealer programming.
Is this part truly plug-and-play?
Yes, because we clone the data from your original module, the replacement BCM will be plug-and-play. In some rare cases, a simple relearn procedure, like for the airbag system, may be required, which can be done with a professional scan tool.
Do I need to return my old BCM as a core?
You only need to send us your original BCM for the data cloning service. There is no core charge, and you can keep your original module after the service is complete.
What happens if my airbag light comes on after installation?
If the airbag light appears, it means the BCM needs to be synchronized with the airbag system’s SDM (Sensing and Diagnostic Module). A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
