The Expert Solution for Your GM’s Electrical Headaches
If you’re dealing with bizarre electrical issues in your 2014-2015 Chevrolet Spark or another compatible GM vehicle—like power windows with a mind of their own, flickering interior lights, or frustrating no-start conditions—you’ve likely met the culprit: a failing Body Control Module (BCM). As the nerve center for your car’s comfort and convenience features, when the BCM goes bad, it can create a cascade of confusing problems. This isn’t just an inconvenience; it can affect your vehicle’s security and daily usability. We offer a reliable, straightforward solution that gets you back on the road without the high costs and long waits at the dealership.
A Technician’s Notebook: The Intermittent Gremlin
I recently had a 2015 Chevy Cruze in my bay with symptoms that drove the owner crazy. The radio would randomly shut off, the turn signals would work one minute and not the next, and occasionally the car wouldn’t recognize the key fob. The owner had already replaced the battery and checked all the fuses. After connecting my diagnostic scanner, I saw multiple ‘Lost Communication with BCM’ codes (U0140). This is a textbook BCM failure. Instead of a costly new module and hours of programming, we used this exact cloning service. The customer sent us their old module, we transferred the data, and sent back the ready-to-install replacement. The car was fixed in a fraction of the time and cost of a dealer visit.
Is Your Vehicle Showing These Telltale BCM Failure Symptoms?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security system light stays on, or the alarm randomly triggers.
- ✔ Problems with the key fob recognition or push-to-start system.
- ✔ The dashboard displays incorrect information or warning lights that won’t turn off.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-series codes.
- ✔ Intermittent starting problems where the engine cranks but won’t start.

A Straightforward Guide to Your BCM Installation
Installing your newly programmed 2014-2015 Spark BCM is a manageable task for a DIY enthusiast or any professional mechanic. The location for the Spark is typically behind the trim panel in the driver’s side left lower a-pillar area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Access the BCM. Its location varies by model (see fitment list below), but it’s often in the driver’s or passenger’s side kick panel or under the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM and unbolt it from its mounting location.
- Install the New BCM: Mount the replacement BCM and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Everything: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
While our cloning service handles the critical programming, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and can typically be performed with a professional scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
Why do you need my original BCM?
Your original BCM contains unique security and configuration data specific to your vehicle’s VIN. By cloning this data to the replacement module, we ensure it communicates perfectly with your car’s other systems, eliminating the need for expensive dealership programming.
Is this BCM truly plug-and-play?
Our cloning service makes it as close as possible. For over 95% of installations, you simply install the module and the vehicle starts and runs correctly. In rare cases, a secondary procedure like an airbag sync or brake pedal relearn may be needed, which requires a professional scan tool.
How long does the entire process take?
Once we receive your original module, our cloning service is typically completed within 24-48 business hours. We then ship the programmed replacement back to you. Total turnaround time will depend on shipping speeds.
What if I don’t send in my old BCM?
This service cannot be completed without your original module. The purchase price includes the cloning service, which is essential for the part to function in your vehicle. We will provide shipping instructions after your purchase.
Is there a core charge?
No, there is no core charge or deposit. We require your original module to perform the programming service, but you will not be charged extra or receive a refund for it.
