Restore Order to Your Cadillac’s Electrical System
Are you battling a storm of bizarre electrical issues in your 2014 Cadillac ATS? One day the power windows have a mind of their own, the next the interior lights won’t turn off, or worse, you’re faced with a frustrating no-start condition. These aren’t random glitches; 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 falters, it can make your car feel unreliable and chaotic. Instead of facing a costly trip to the dealership for diagnostics and programming, we offer a straightforward, reliable solution.
This is a fully tested Body Control Module, compatible with part number 13594769 and others. The key to our service is the professional cloning of your original module’s data. You simply send us your faulty BCM, and our technicians will transfer all the critical vehicle-specific information—including VIN, mileage, and security keys—to this replacement unit. The result? A true plug-and-play module that restores full functionality without any additional programming required on your end. It’s the most efficient way to get your 2014 ATS BCM working correctly again.
Is Your Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ Erratic instrument cluster behavior or warning lights (like the security lamp).
- ✔ The vehicle fails to start, but the battery and starter are good.
- ✔ Remote key fob not working correctly.
- ✔ Communication failure codes, such as U0140, stored in other modules.
A Technician’s Notebook: The Misleading No-Start
I had a 2014 Sierra in the bay that wouldn’t crank. The owner had already replaced the battery and starter. Scans showed a ‘Lost Communication with BCM’ code (U0140). While many would jump to replacing the BCM, I always check the basics first. On these GM platforms, a corroded ground connection near the BCM’s location (under the steering column) can mimic a complete failure. After cleaning the main ground point, the truck started right up. However, about 20% of the time, the BCM itself is the culprit due to internal circuit board issues. This cloning service is the perfect fix for those confirmed BCM failures, saving my customers hundreds compared to a new, dealer-programmed part.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2014 Cadillac ATS, the BCM is typically located on the firewall in the driver’s side footwell area. Refer to a service manual for the exact position.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: 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 ignition to the ‘ON’ position and test all body functions—windows, locks, lights, and wipers—to confirm proper operation.
Post-Installation Checks
Our programming service makes this a plug-and-play repair, but some vehicle systems may require a quick sync. Don’t be alarmed if you see one of the following; these are easily resolved:
- Airbag Light: If the airbag warning light is on, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system with the new BCM and can be done with a professional-grade scan tool.
- Brake Pedal Position: In some cases, a Brake Pedal Position Relearn may be required to ensure your brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. For detailed procedures specific to your model, always consult a factory service manual or a certified automotive technician.

Frequently Asked Questions about our BCM Service
How does the mail-in programming service work?
It’s simple. After you place your order, we will contact you with detailed instructions for shipping your original BCM to our facility. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, typically within 1-2 business days. We handle all the technical work.
Do I need to send my VIN or any other information?
No, you do not need to provide your VIN separately. All the necessary information is contained within your original module’s memory. Our cloning process extracts everything required for a perfect match to your vehicle.
Is this a guaranteed fix for my car’s problems?
This service provides a fully functional, correctly programmed 2014 ATS BCM. If your vehicle’s issues are caused by a faulty BCM, this will resolve them. However, it’s crucial to ensure the BCM has been properly diagnosed as the source of the problem, as wiring or other module issues can cause similar symptoms.
What if I don’t have my original BCM?
This specific service requires your original module for the data cloning process. If your original BCM is lost or completely destroyed, please contact us to discuss alternative solutions we may have available.
Do I need to return my old BCM after installation?
No, there is no core charge for this part. You are welcome to keep your original module after you send it to us for the initial data transfer.
