Is Your Cadillac or GM Vehicle Acting Possessed?
If you’re experiencing a frustrating array of electrical problems in your 2014 Cadillac ATS, Corvette, Silverado, or other compatible GM model, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to your interior lighting and security system. When it starts to fail, it can create bizarre, intermittent, and hard-to-diagnose issues that can drive any owner crazy.
Diagnosing a Faulty 2014 Cadillac ATS BCM
A failing BCM doesn’t always trigger a check engine light. Instead, it manifests as a collection of strange electrical symptoms. You might be dealing with a bad BCM if you’re noticing several of the issues below. This module is a direct replacement for part numbers 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.
From the Diagnostic Bay
We had a 2014 Sierra 1500 come into the shop with a complaint of the driver’s side power window only working when it wanted to. The customer had already replaced the window switch and the motor, with no change. After checking the wiring diagrams, we suspected the BCM, as it directly controls the window relay. Instead of a costly diagnostic and programming session at the dealer, we used our cloning service. We transferred the data from his original BCM to a replacement unit. After a quick 15-minute install, the window worked perfectly every time. It’s a classic case where the BCM was the hidden cause of a seemingly simple problem.
Common Symptoms of BCM Failure
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights) staying on, flickering, or not turning on.
- ✔ The security system or keyless entry malfunctioning, or the alarm sounding for no reason.
- ✔ Dashboard warning lights appearing intermittently.
- ✔ Radio or infotainment system issues, such as turning on/off by itself.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ A ‘no-start’ condition where the starter doesn’t engage, even with a good battery.
The Simple, Plug-and-Play Solution
Forget expensive dealership visits and complex programming procedures. Our professional cloning service makes this repair straightforward and affordable. We transfer the essential data—including your vehicle’s VIN, key information, and specific options—from your original BCM directly onto this replacement unit. The result is a module that is 100% plug-and-play. Simply install it, and your vehicle’s electronics are restored.

Post-Installation Notes
While our goal is a seamless plug-and-play experience, some GM vehicles may require minor recalibration procedures after installation. These are typically simple and can be performed with a capable scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the systems. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What does ‘cloning’ or ‘programming’ mean for a BCM?
It means we transfer your vehicle’s specific configuration data, including the VIN and security information, from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your car, avoiding the need for expensive dealer programming.
Is this BCM difficult to install?
No, the physical installation is typically straightforward. The BCM is usually located under the dashboard or on the firewall. Once you install our pre-programmed module, it’s plug-and-play, and your vehicle should start and run with all functions restored.
What if my original BCM is completely dead or unreadable?
In many cases, even if the BCM has failed, we can still extract the necessary data. If you suspect your module is severely damaged (e.g., by water or fire), please contact us before ordering to discuss options.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary key and security data is stored within the BCM itself, which is what we transfer during the cloning process.
How long does the entire process take?
Once we receive your original module, our programming service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We always ship the completed module back to you promptly with tracking.
