Restore Your Vehicle’s Electrical Sanity
If you’re dealing with a cascade of bizarre electrical problems in your 2015 Cadillac Escalade or another GM vehicle—from flickering lights and malfunctioning power windows to a security system that has a mind of its own—the root cause is often a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating guessing game. This isn’t just an inconvenience; it can affect vehicle security and safety systems. Stop chasing individual symptoms and address the core issue with a reliable, pre-programmed BCM.
This listing is for a replacement BCM, part number 13594692, that is professionally programmed with your vehicle’s specific data. Our unique cloning service makes this a true plug-and-play solution. You simply ship us your original BCM, we transfer all the critical information (like VIN, options, and key data) to this replacement unit, and ship it back to you ready for installation. This process bypasses the expensive and time-consuming programming required at a dealership, saving you hundreds of dollars and significant downtime. It’s the most efficient way to get your vehicle back to 100% functionality.
From the Diagnostic Bay: The Suburban with a Ghost
A customer brought in a 2015 Suburban with a list of complaints that sounded like a haunting. The radio would randomly shut off, the dome lights would flicker while driving, and occasionally the power liftgate wouldn’t respond. They had already replaced the battery and checked fuses with no luck. In my experience, when multiple, unrelated electronic systems act up intermittently, the BCM is the prime suspect. After confirming solid power and ground to the module, we identified it as the culprit. Instead of a costly new module and dealer programming, we used a cloned unit like this one. The installation took less than an hour, and every single electrical gremlin was gone. The customer was thrilled to have their reliable family hauler back without a massive repair bill.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is likely the component to inspect. Look out for:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication error codes, such as U0140, stored in the system.
- ✔ Issues with the HVAC (climate control) system’s blower motor or mode doors.
A Straightforward Guide to BCM Installation
Thanks to our programming service, installing your replacement 2015 Escalade BCM is a direct swap. While the exact location varies slightly by model (see fitment list), it’s typically found under the steering column or on the driver’s side of the dash/firewall.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: Find your original BCM. In most of these trucks and SUVs, it’s located under the driver’s side dash, near the steering column.
- Disconnect and Remove: Carefully unplug all electrical connectors from the module. Take a photo beforehand if it helps you remember their positions. Then, unbolt the module from its mounting bracket.
- Install the New Module: Mount your pre-programmed replacement BCM in the same location and securely reconnect all the electrical harnesses.
- Reconnect Battery: Reattach the negative battery terminal and tighten it securely.
- Test All Functions: Start the vehicle and test all the features controlled by the BCM: lights, locks, windows, horn, wipers, etc., to confirm the repair.
- Post-Installation Checks: In some cases, additional steps may be needed. If the airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary for proper brake light and traction control function.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, usually within 1-2 business days.
Do I have to send my original BCM in?
Yes. This is essential for our cloning process. Transferring the data from your original module is what makes the replacement unit a plug-and-play part and prevents the need for dealer programming.
Is there a core charge for my old module?
No, there is absolutely no core charge. After we clone the data, we will ship your original module back to you along with the newly programmed replacement.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty BCM. If you are experiencing symptoms like erratic lights, lock failures, and other body electronic issues, this is very likely the solution. Proper vehicle diagnosis is always recommended.
What if the airbag light comes on after installation?
This can happen occasionally. It simply means the BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
