Is Your Vehicle Plagued by Bizarre Electrical Problems?
If your Chevrolet Spark, Cruze, Equinox, or another compatible GM vehicle is experiencing strange and unpredictable electrical issues, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your car’s body electronics, managing everything from power windows and door locks to interior lighting, security systems, and communication between other modules. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2014 Chevy Cruze come into the shop with a list of complaints that seemed endless. The radio would turn off randomly, the dome light would flicker, and sometimes the car wouldn’t recognize the key fob. The owner had been to two other shops that couldn’t pinpoint the issue. After running network diagnostics, we noticed communication dropouts originating from the BCM. It wasn’t throwing a hard code, but it was silently corrupting the data network. Swapping in a programmed BCM solved every single issue instantly. It’s a perfect example of how a faulty BCM can wreak havoc in ways that aren’t always obvious.
The Simple, No-Dealer-Visit Solution
Getting a new BCM from the dealership often involves expensive parts, labor, and complex programming procedures that tie your car up for days. Our solution bypasses that entire headache. We provide a replacement BCM that is precisely cloned from your original unit. This means all your vehicle’s specific data—including the VIN, mileage, and security key information—is transferred to the replacement module. The result is a true plug-and-play component that restores your vehicle’s functionality without requiring a trip to the dealer for programming.
Signs Your BCM May Be Failing
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The anti-theft or security system acting up, preventing the car from starting.
- ✔ Dashboard warning lights appearing for no reason (e.g., airbag, ABS).
- ✔ Key fob not being recognized or working sporadically.
- ✔ Wipers or turn signals behaving erratically.
- ✔ Complete loss of power to various accessories.
Your Go-To Solution for a 2014-2015 Spark BCM
This service is the definitive repair for your 2014-2015 Spark BCM and a wide range of other GM vehicles. By cloning your original module, we ensure 100% compatibility and retain all the factory settings your vehicle came with. You don’t have to worry about mismatched software or features that suddenly stop working. Simply send us your original BCM, and we’ll handle the complex data transfer. We then ship your ready-to-install replacement module back to you, typically within a few business days.
Installation and Post-Install Checks
Physically installing the BCM is usually straightforward, as it’s often located in an accessible spot like behind the driver’s side kick panel or under the dash. Once installed, the module is ready to go. However, in some cases, a couple of simple relearn procedures may be necessary:
- 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration might be required.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions and 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 controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the central hub for your car’s body electronics.
How does this mail-in programming service work?
After you place your order, we will provide instructions for shipping your original BCM to us. Once we receive it, we extract the vehicle-specific data and transfer it to the replacement module. We then ship the fully programmed, ready-to-install BCM back to you.
Is this module truly plug-and-play?
Yes, because we clone the data from your original unit, the replacement module will be plug-and-play. It requires no additional programming from a dealer. In some rare cases, a simple relearn procedure for the airbag or brake pedal sensor may be needed, as noted in the description.
Why do I need to send in my original BCM?
Your original BCM contains critical security and configuration data that is unique to your vehicle’s VIN. By cloning this data, we ensure the replacement module communicates perfectly with your car’s other systems, preventing anti-theft lockouts and other compatibility issues.
What happens if the airbag light comes on after installation?
If the airbag light appears, it means the BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). This is done with a professional scan tool using the ‘Setup SDM Primary Key in BCM’ function. It’s a quick procedure for any qualified technician.
Will this fit other vehicles besides the 2014-2015 Spark?
Yes, this BCM fits a wide range of GM vehicles, including the Equinox, Cruze, Verano, Volt, and more. Please check the compatible part numbers and the fitment list in the description to confirm it’s correct for your vehicle.
