Is Your Vehicle Plagued by Electrical Gremlins?
If your Chevrolet Cruze, Buick Regal, or GMC Terrain is suddenly behaving erratically—with flickering lights, malfunctioning power windows, a horn that won’t work, or strange warning messages on the dash—the culprit is often a failing Body Control Module (BCM). The BCM is 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 confusing and frustrating problems that can be difficult to diagnose.
The Simple, Plug-and-Play Solution
Instead of paying for expensive diagnostic time and dealership programming fees, our service provides a straightforward and reliable solution. We take a replacement BCM and program it by cloning the essential data from your vehicle’s original module. This process ensures that the replacement unit is a perfect match for your car’s specific configuration and security settings. The result is a truly plug-and-play module that restores full functionality without any additional programming required on your end.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The security system acting up, or the vehicle not recognizing the key fob.
- ✔ Horn, windshield wipers, or radio functioning erratically.
- ✔ False warning lights on the instrument cluster (e.g., airbag, ABS, traction control).
- ✔ Inability to communicate with the module using a diagnostic scan tool.
- ✔ Complete loss of power to multiple electronic accessories at once.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a relearn or synchronization procedure after the new BCM is installed. This is normal and does not indicate a problem with the module.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary. This ensures the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. 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 many of the electronic accessories not related to the engine, such as power windows, lights, door locks, wipers, and the security system.
How does this programming service work?
You purchase the service and ship your original BCM to us. We then extract the unique data from your module and flash it onto the replacement unit. This makes the new module an exact electronic copy of your old one, ensuring seamless integration with your vehicle.
Will I need to visit a dealer for programming?
No. The BCM you receive from us will be fully programmed and ready for installation. Our service completely eliminates the need for any additional programming by a dealership or mechanic, saving you time and money.
What happens if my airbag light comes on after installation?
This is a common security feature. The new BCM needs to be synchronized with the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to turn off the light.
Is this a guaranteed fix for my vehicle’s problems?
This service corrects issues directly caused by a faulty BCM. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
