Restore Control and End Electrical Frustration in Your GM Vehicle
Are you chasing down bizarre electrical gremlins in your 2014 Cadillac CTS? One minute the power windows work, the next they don’t. Perhaps the security light is flashing, your interior lights are flickering, or the car refuses to start intermittently. These aren’t random quirks; they are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable problems. Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a simple, reliable, and affordable solution.
This is a comprehensive cloning service for your vehicle’s BCM. You simply ship your original module to our facility. Our expert technicians will then transfer all the critical vehicle-specific data—including VIN, key information, and security settings—to this fully tested replacement module. We then ship the ready-to-install BCM back to you. The result is a true plug-and-play component that restores full functionality without any additional programming required on your end. It’s the most efficient way to get your car back to 100%.
A Technician’s Notebook: The Case of the Haunted Cadillac
A few months back, a 2014 CTS was towed into the shop. The owner was at his wit’s end. He described the car as being “haunted.” The radio would change stations on its own, the dome lights would flicker while driving, and twice it had left him stranded with a no-crank, no-start condition. He had already replaced the battery and checked the main grounds. A quick scan revealed a slew of communication error codes, most pointing towards the BCM (DTC U0140 – Lost Communication With Body Control Module). Instead of ordering a blank module from the dealer, which would have meant towing the car there for programming, we used our cloning service. The customer removed his BCM, we cloned it overnight, and he had the replacement the next day. He plugged it in, and every single issue was resolved instantly. It’s a perfect example of how the right part, correctly prepared, can save hundreds of dollars and days of downtime.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. A failing module can often log diagnostic trouble codes (DTCs) such as U0140, U0155, or various B-codes related to specific body functions.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The anti-theft or security system light is illuminated, preventing the engine from starting.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar”).
- ✔ Complete loss of communication with the diagnostic scan tool.
Your Straightforward Installation Guide
Installing your pre-programmed BCM is a simple swap. Since we’ve handled all the programming, you won’t need any special tools for the installation itself. The BCM on a 2014 CTS is typically located in the left-hand side of the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: Access the BCM. On most listed models, this involves removing lower dash panels or accessing the area near the steering column or left-hand firewall.
- Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the exact same location. Reconnect all electrical connectors, ensuring they are fully seated and locked in place.
- Power Up: Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position and test all functions—windows, locks, lights, and starting—to confirm the repair.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure to sync related systems. These are not always necessary but are important to be aware of.
- 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: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light operation and stability control function.
Disclaimer: Always consult a factory service manual for your specific vehicle for detailed instructions and torque specs. No core charge is required for this service; you can keep your original module.

Frequently Asked Questions
How does this BCM cloning service work?
It’s a simple 3-step process: 1) You purchase this service and ship your original BCM to us. 2) We transfer 100% of your vehicle’s data to the replacement module. 3) We ship the plug-and-play module back to you, ready for installation.
Is this really a plug-and-play solution?
Yes. Because we clone your original data, the replacement module will work immediately upon installation without requiring a trip to the dealer for programming. In some rare cases, a simple relearn procedure for the airbag or brake pedal sensor may be needed, which requires a professional scan tool.
Where is the BCM located on my 2014 Cadillac CTS?
On the 2014 Cadillac CTS Sedan (VIN A, New Style), the Body Control Module is located on the left-hand side of the dashboard.
Do I need to send my keys or any other parts?
No. We only need your original Body Control Module. All the necessary key and security information is stored within the BCM itself, which we will transfer to the new unit.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old module back to us after the repair, though we do need it initially for the data cloning service.
