Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Dealing with bizarre electrical issues in your 2014 Chevy Impala or another compatible GM vehicle? Intermittent power windows, flickering dash lights, a security system that acts up, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. It’s the central hub for your car’s body electronics, and when it goes, chaos ensues.
Forget the expensive dealership visit and the days of vehicle downtime waiting for programming. This is a fully programmed BCM, ready for installation upon its return to you. Our professional cloning service makes this repair straightforward. We transfer the critical data from your original, failing BCM directly onto this replacement unit. This ensures that all your vehicle’s specific settings, security information, and options are preserved, making the installation process as simple as swapping the part. This is the most reliable and cost-effective way to get your car back to 100%.
Common Signs of a Failing BCM
- ✔ Unresponsive power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Erratic or non-functional dashboard gauges and warning lights (e.g., ABS, Traction Control).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Rapid battery drain while the vehicle is off.
- ✔ Communication error codes (U-codes) when scanned with a diagnostic tool.
From the Diagnostic Bay: The Case of the Haunted Impala
A customer brought in a 2014 Impala with a list of problems that sounded like something out of a ghost story. The radio would change stations on its own, the dome light would flicker at random, and worst of all, the car would sometimes refuse to start. The battery and alternator checked out perfectly. After hooking up my scan tool, I found a slew of communication codes pointing to the BCM. On this specific model, the BCM is located on the driver’s side dash, and a visual inspection revealed evidence of water intrusion from a leaky windshield seal—a common killer of these modules. By cloning his original BCM, we preserved all the key data and had him back on the road the same day he got the part back, without a single trip to the dealer.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2014 Impala (New Style, VIN 1), the BCM is located on the left-hand (driver’s) side of the dash. For other models, refer to the fitment list for its location.
- ✔ Remove the Original Module: Carefully disconnect all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the Replacement: Mount your newly programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: windows, locks, lights, and radio. Start the vehicle to ensure it runs correctly.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the BCM and is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function as intended.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Specific procedures can vary slightly by vehicle.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you with tracking.
Do I need to have a dealer program this 2014 Impala BCM?
No. The main benefit of our service is that the module arrives pre-programmed with your car’s specific data. This eliminates the need for expensive and time-consuming dealership programming.
Is there a core charge or do I need to return my old part?
There is no core charge. We only need your original module to perform the data cloning service. You can keep your original module after the service is complete.
What tools are required for installation?
Basic hand tools are typically all that’s needed, such as a socket set and screwdrivers to access and unbolt the module. No special electronic tools are required for the physical installation.
What if the airbag light comes on after I install it?
This is a possibility. It means the airbag system needs to be synced with the new BCM. A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
