Fix Bizarre Electrical Issues with a Plug-and-Play BCM
Are you dealing with a vehicle that seems to have a mind of its own? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a car that refuses to start can all point to a single, frustrating culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s electronics, when the BCM goes bad, it can create a cascade of confusing and costly problems. This is the definitive, hassle-free solution for your 2014 XTS BCM and a wide range of other GM vehicles.
We take the guesswork and expensive dealership programming out of the equation. Our unique cloning service makes this repair straightforward. Simply send us your original BCM, and we will transfer all of its critical data—including VIN, mileage, and key information—to this replacement unit. The module you receive back will be 100% plug-and-play, ready to install without any need for a trip to the dealer for expensive calibration. It’s the most efficient way to restore your vehicle’s proper function.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2014 Cadillac CTS that came into the shop with a laundry list of complaints from the owner. The interior lights would pulse randomly, the radio would shut off, and occasionally, the car wouldn’t recognize the key fob. The owner had already replaced the battery and was convinced he had a parasitic draw he couldn’t find. After hooking up the scan tool, I saw a slew of communication errors (U-codes) pointing to the BCM. Instead of a complex wiring issue, the BCM itself was failing internally, corrupting the data network. A cloned BCM like this one solved every single issue in under an hour of shop time. It’s a common failure I’ve seen dozens of times, and this service is the fastest path to a reliable fix.
Is Your Vehicle Exhibiting These Frustrating Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from dashboard lights, gauges, or the driver information center.
- ✔ Security system faults or a vehicle that won’t start due to anti-theft issues.
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with other modules (e.g., U0140, U0155).
- ✔ Wipers or climate control functions working incorrectly.
Your Straightforward Installation Guide
Thanks to our cloning service, installing your replacement 2014 XTS BCM is a simple swap. While the exact location varies by model, the general process is consistent.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate Your BCM: On the 2014 Cadillac XTS, the BCM is typically found behind the left front hinge pillar area. For trucks and SUVs, it’s often under the steering column or on the driver’s side firewall. Consult a service manual for your specific vehicle’s location.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Power Up: Reconnect the negative battery terminal. Your vehicle’s electronics should now function correctly with the pre-programmed module.
Important Post-Installation Information
In some cases, minor follow-up procedures may be needed to ensure all systems are perfectly synced:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This must be done with a professional-grade scan tool to re-establish communication between the BCM and the airbag system.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor relearn to ensure brake lights and stability control systems function as designed.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a certified technician for procedures specific to your make and model.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for you to ship your original BCM to us. Our technicians will then extract the unique data from your module and flash it onto the replacement unit. We then ship the plug-and-play module back to you.
Do I have to get this programmed at the dealership?
No. Our cloning service completely eliminates the need for dealership programming, saving you time and money. The module you receive will be ready for immediate installation.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related electronic features, such as power windows, lights, security systems, wipers, and door locks.
Is there a core charge?
No, there is no core charge for this part. You are required to send your original module in for the data transfer, but you do not need to leave it with us.
What if the airbag light comes on after I install it?
This is a known possibility. The BCM and the airbag module (SDM) need to be synced. A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
