Restore Control and End Electrical Frustrations in Your GM Vehicle
Are you battling bizarre electrical issues in your 2015 Cadillac Escalade ESV? Flickering lights, unresponsive power windows, or random warning messages can all point to a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can turn your luxury SUV into a source of constant annoyance. In my 20+ years as a technician, I’ve seen how a failing BCM can mimic a dozen other problems, leading to wasted time and money on incorrect diagnoses. This isn’t just a part; it’s the solution to restoring order and predictability to your vehicle’s essential functions.
This listing is for a replacement BCM, part number 13594692 (also compatible with 13593214, 13594768, 13580690, 13591519, and 13594769), that comes with a critical service: we professionally clone the data from your original module. This means you get a component that is 100% plug-and-play, with no need for an expensive trip to the dealership for programming. Simply send us your old BCM, and we’ll transfer all the vehicle-specific information—like key fob data and factory options—to this replacement unit. We handle the complex part so you can get back on the road with confidence.
A Technician’s Notebook: The Tahoe with a Mind of Its Own
A customer brought in a 2015 Tahoe, a close cousin to the Escalade, with a laundry list of complaints: the radio would shut off randomly, the dome lights would stay on, draining the battery overnight, and the power locks worked intermittently. They had already replaced the battery and alternator to no avail. After hooking up the scan tool, I saw a slew of communication errors (U-codes) between various modules. This is a classic sign that the central traffic controller—the BCM—is failing. Instead of communicating properly, it was sending garbage data, causing chaos. By installing a cloned 2015 Escalade ESV BCM (the platform is nearly identical), all the ghost-like issues vanished instantly. This is why our cloning service is so vital; it preserves the vehicle’s unique identity, making the repair seamless.
Common Signs of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t turn on at all.
- ✔ The security system acting erratically or preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Communication error codes, often in the U-series (e.g., U0140 – Lost Communication With Body Control Module).
- ✔ HVAC (Air Conditioning and Heat) controls not responding correctly.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2015 Escalade ESV and similar GM trucks/SUVs, the BCM is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ 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 your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting the engine) and test all body functions: lights, windows, locks, radio, etc.
Important Post-Installation Steps
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function as intended.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Vehicle systems can vary.

Frequently Asked Questions
Frequently Asked Questions
What is the cloning service and how does it work?
Our cloning service is a simple process. After you purchase, we will provide instructions for you to ship your original BCM to us. We then use specialized equipment to extract the unique data and transfer it to the replacement module. This makes the new module an exact electronic copy of your old one, eliminating the need for dealer programming.
Do I need to send my original BCM to you?
Yes, this service requires you to send us your original module. This is the only way we can perform the cloning process to ensure the replacement BCM is 100% plug-and-play for your specific vehicle.
Is there a core charge for this part?
No, there is no core charge. We need your original module for data transfer only. You are welcome to have it shipped back to you with your newly programmed module if you wish.
Will this fix a no-start issue?
A failing BCM can cause a no-start condition if the anti-theft system (Pass-Key/Passlock) is malfunctioning. Because our process clones your key data, it can resolve these security-related starting problems. However, a no-start can have many causes, so proper diagnosis is always recommended.
What if my part number isn’t an exact match but is on your list?
This module, part number 13594692, is a direct superseding replacement for all the part numbers listed in our description (including 13593214). As long as your original part number is on our compatible list, this module will work perfectly for your vehicle after our cloning service.
