Tired of Unpredictable Electrical Problems in Your Cadillac?
Is your 2014 Cadillac ATS or another GM vehicle acting possessed? One day the power windows don’t work, the next the radio is on the fritz, and the dashboard is lighting up with random warnings. These frustrating, intermittent issues often point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to security systems and climate control. When it starts to fail, it can create a cascade of confusing and seemingly unrelated problems.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a streamlined, reliable solution. This listing is for a replacement BCM, part number 13594692, that comes ready for installation through our professional cloning service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module, eliminating the need for any additional programming or dealer intervention.
A Technician’s Notebook: The Ghost in the Cadillac
I remember a 2014 Cadillac ATS that came into the shop with the most bizarre symptoms. The owner complained of the horn honking randomly, the interior lights flickering while driving, and an intermittent no-start condition. He’d been to two other shops that couldn’t find the issue because it never acted up for them. After running network diagnostics, I noticed communication dropouts with the BCM. We swapped in one of our pre-programmed modules, and the electrical gremlins vanished instantly. It’s a classic case where the BCM fails internally, causing data corruption that standard scanners can’t always pinpoint. This cloning service is the exact fix we use to get these cars back on the road reliably.
Key Symptoms of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the cause. A failing module can often set communication codes like U0140, U0155, or other U-series DTCs.
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or won’t turn on at all.
- ✔ The security system acting up, causing no-start or alarm issues.
- ✔ Wipers or radio operating intermittently or incorrectly.
- ✔ False warning messages on the instrument cluster (e.g., ‘Service Theft Deterrent System’).
- ✔ Inconsistent A/C and climate control operation.
Your Simple Path to a Reliable Fix: The 2014 ATS BCM Service
Our process is designed to be as simple as possible. After your purchase, we will contact you with clear, step-by-step instructions for shipping your original module to our facility. Once we receive it, our technicians will perform the data transfer to the replacement BCM and ship it back to you, typically within one business day. You’ll receive tracking information so you know exactly when to expect your ready-to-install part.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- ✔ Locate the BCM: On a 2014 Cadillac ATS, the Body Control Module is typically located on the firewall in the driver’s side footwell area. For other models, it may be under the steering column or behind the dash. A quick search for your specific model will confirm the 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 the module from its mounting bracket.
- ✔ Install the New Module: Mount the replacement BCM you received from us and securely reconnect all the electrical connectors.
- ✔ Power Up: Reconnect the negative battery terminal. Your vehicle’s essential data is already on the module, so it’s ready to go.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does this cloning service work?
After you place your order, you will ship your original BCM to us. We will then professionally transfer all of your vehicle’s specific programming and security data to the replacement BCM. We then ship the programmed module back to you, ready for installation.
Is this BCM truly plug-and-play?
Yes, because we clone the data from your original module, the replacement BCM will be plug-and-play. This avoids any need for expensive dealership programming. In some rare cases, a minor relearn procedure like for the airbag or brake pedal sensor may be needed post-installation.
Do I have to send my original BCM in?
Yes, sending your original module is required. This is the only way we can extract the unique data needed to program the replacement unit, ensuring a perfect match for your vehicle.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data from the memory chip. Please contact us if you have concerns about the condition of your module.
Is there a core charge for this part?
No, there is no core charge. You are free to keep your original module after the service is complete.
