Restore Your Cadillac’s Functionality with a Hassle-Free BCM Solution
If you’re dealing with bizarre electrical issues in your 2014-2016 Cadillac ELR—like power windows with a mind of their own, flickering interior lights, a security system that won’t cooperate, or even a no-start condition—the Body Control Module (BCM) is often the culprit. As a technician with over two decades of experience, I’ve seen how a failing BCM can turn a sophisticated vehicle into a source of constant frustration. It’s the central hub for your car’s body electronics, and when it goes, chaos ensues.
Forget the expensive trip to the dealership and the high cost of programming a brand-new module from scratch. We offer a streamlined, reliable solution. This is a replacement BCM that comes pre-programmed with your vehicle’s exact data. The process is simple: you purchase this module, ship your original BCM to us, and we handle the rest. We’ll meticulously transfer all the critical information—including VIN, key data, and specific vehicle options—to this replacement unit. We then ship the ready-to-install module back to you, eliminating the need for any on-car programming. This is the most direct path to getting your 2014-2016 ELR BCM replaced and your car back to normal.
A Technician’s Notebook: The Intermittent Gremlin
I once had a 2015 Cadillac SRX in the bay with a complaint that defied logic. The radio would randomly shut off, the driver’s side window would stop working, and the key fob would only work intermittently. The owner had already replaced the battery and checked all the fuses. Scans showed a slew of U-codes, specifically U0140 (Lost Communication With Body Control Module). The tricky part was that the issue was intermittent. After wiggling the main harness connected to the BCM, I was able to replicate every single symptom. This confirmed a fault internal to the module, not just a bad connection. A cloned BCM like this one solved the problem in an afternoon, without the high cost and scheduling headache of dealership service.
Key Symptoms of a Failing BCM
- âś” Erratic or non-functional power windows, door locks, and interior/exterior lights.
- âś” The security system or anti-theft light is always on or flashing, preventing the car from starting.
- âś” Key fobs are not being recognized by the vehicle.
- âś” Multiple, seemingly unrelated warning lights appearing on the dashboard.
- âś” Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- âś” Wipers or other accessories activating on their own or not working at all.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any work on the electrical system.
- âś” Locate the BCM: On the 2014-2016 Cadillac ELR, the Body Control Module is typically located in the right-hand (passenger side) cowl area. You may need to remove trim panels for access.
- âś” Disconnect and Remove: Carefully unplug all electrical connectors from your original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- âś” Ship Your Original Module: After your purchase, we will contact you with detailed instructions for shipping your original BCM to our facility.
- âś” Install the Replacement: Once you receive the programmed module back from us, simply mount it in place and reconnect all the electrical connectors.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
While our programming service makes this a near plug-and-play repair, some GM vehicles may require minor post-installation procedures. These are typically only necessary if a specific warning light appears:
- Airbag System Sync: If the airbag warning light is on 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 recalibration might be required to ensure proper brake light and traction control operation.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to mail your original BCM to us. We then copy the essential data from your module to the replacement unit and ship it back to you, usually within 1-2 business days of receiving your part.
Do I need to do any programming myself?
No. The module you receive will be fully programmed and ready for installation. This service eliminates the need for expensive dealer tools or software subscriptions.
Why do you need my original BCM?
Your original BCM contains the unique vehicle identification number (VIN), security information, and option configurations for your specific car. Cloning this data ensures the replacement module works seamlessly with all other computers in your vehicle.
Is there a core charge?
No, there is no core charge for this service. You can keep your original, non-functional module.
What if my airbag light comes on after installation?
This is a possibility on some GM vehicles. It simply means the airbag module needs to be re-synced with the BCM. A procedure called ‘Setup SDM Primary Key in BCM’ can be performed by most professional repair shops with a capable scan tool.
What part number should I match?
This unit, part number 13592376, replaces a wide range of part numbers listed in the description. As long as your vehicle is on the compatibility list, this module will work for you.
