Restore Your Vehicle’s Electrical System and End the Frustration
Are you dealing with a cascade of bizarre electrical issues in your Cadillac or GM vehicle? Flickering lights, windows that won’t respond, a security system that acts up, or a dashboard lit up with warning lights for no apparent reason? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s comfort and convenience features. When it falters, it can make driving a nightmare. This pre-programmed BCM, compatible with part numbers like 13594768 and 13594692, is the definitive solution to get your vehicle back to normal without the exorbitant costs and scheduling headaches of a dealership visit.
From the Diagnostic Bay: The Case of the Haunted Truck
I remember a 2014 Sierra 1500 that came into my shop a few years back. The owner was at his wit’s end. The horn would blare randomly, the interior lights would flicker while driving, and the radio would shut off intermittently. He’d already replaced the battery and checked the main grounds. Using my scan tool, I saw a dozen communication codes (U-codes) pointing to lost communication with various modules. This pattern doesn’t usually mean a dozen failed parts; it means the central hub—the BCM—is failing. We confirmed it was a faulty 2014 ATS BCM (the same family as the Sierra’s). By providing a cloned module, we saved him over $700 in dealership fees and had him back on the road the next day, completely trouble-free. This is the exact service we offer here.
Is Your Vehicle Exhibiting These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need. In my 20+ years of experience, these are the most common indicators:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system preventing the car from starting.
- ✔ Unresponsive key fob and remote entry functions.
- ✔ Instrument cluster gauges behaving strangely or warning lights appearing without cause.
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs, stored in the system.
How Our Simple Plug & Play Programming Service Works
We eliminate the need for expensive dealership tools and programming. Our process is designed to be straightforward for both professional technicians and DIY enthusiasts. We transfer the critical data from your original BCM to this replacement unit, making the installation a simple swap. 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 cloning and ship your ready-to-install BCM back to you, typically within one business day. You’ll receive tracking information so you know exactly when to expect it. Best of all, there is no core charge; you can keep your original module.
Your Straightforward BCM Installation Guide
Installing your newly programmed 2014 ATS BCM is a manageable job for anyone with basic tools. While the exact location varies by model (e.g., on the firewall for the ATS, under the steering column for a Sierra), the general process is consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the Original BCM: Consult your vehicle’s service manual or a reliable online resource to find the BCM. It’s typically located in the driver’s or passenger’s side footwell area, often behind a kick panel or near the firewall.
- 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 in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal. Your vehicle’s core functions should now be restored.
Important Post-Installation Notes
In some cases, specific systems may require a quick synchronization after the BCM is installed. This is normal and can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag (SRS) warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the systems. This ensures the safety system is fully operational.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to satisfy the traction control system.
- Disclaimer: Always refer to a factory service manual for procedures specific to your vehicle’s year, make, and model.

Frequently Asked Questions
What exactly does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and more. When it fails, these systems can become erratic.
Why do I need to send my original BCM to you?
Your original BCM contains specific security and options data unique to your vehicle’s VIN. We clone this data to the replacement module. This makes the new part plug-and-play, saving you from a costly and complicated programming procedure at a dealership.
Is this something I can install myself?
Yes, absolutely. Because we handle all the programming, the physical installation is just a matter of swapping the modules. It’s a job most DIYers with basic hand tools can complete in under an hour by following our guide.
What if my original module is completely dead or water damaged?
In many cases, even if the module is non-functional in the vehicle, we can still extract the necessary data from the memory chip. Please contact us before ordering if your BCM has severe physical or water damage so we can confirm the likelihood of a successful data recovery.
What is the turnaround time for the programming service?
We pride ourselves on a fast service. We will program and ship your replacement BCM back to you within one business day of receiving your original module.
