Restore Your Cadillac’s Brainpower and Eliminate Electrical Frustrations
Is your 2014-2016 Cadillac ELR acting possessed? Flickering interior lights, power windows with a mind of their own, or a security system that randomly triggers are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s comfort and convenience features. When it fails, it can cause a cascade of confusing and annoying problems. Dealerships will quote you a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a fully tested, replacement BCM that comes ready for installation. We handle the complex part for you through our professional mail-in cloning service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module that restores full functionality to your vehicle without any need for expensive dealer tools or additional programming on your end. It’s the most reliable and cost-effective way to solve your electrical woes and get your sophisticated ELR working like new again.
From the Diagnostic Bay: The ELR with a Mind of Its Own
A customer brought in a ’15 ELR with a laundry list of bizarre issues: the radio would shut off intermittently, the passenger window wouldn’t respond, and the dome light would stay on, draining the battery. They had already replaced the battery and checked fuses, but the gremlins persisted. After hooking up my scan tool, I saw a slew of communication error codes (U-codes) pointing to the BCM. Instead of a costly new unit, we used this exact mail-in programming service. Once the cloned module arrived, installation took under an hour. Every single electrical issue was resolved instantly. It’s a textbook example of how a faulty 2014-2016 ELR BCM can mimic multiple other failures, and how cloning is the most direct fix.
Is Your Cadillac Showing These Symptoms?
- ✔️ Power windows, door locks, or mirrors not working or operating erratically.
- ✔️ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔️ The anti-theft or security system malfunctioning or preventing the car from starting.
- ✔️ Inaccurate or dead gauges on the instrument cluster.
- ✔️ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140.
- ✔️ Remote keyless entry failing to lock or unlock the doors.
A Straightforward Guide to Our Mail-In Service & Installation
- ✔ Place Your Order: Purchase this BCM, and we will contact you with detailed instructions and a shipping address. Please ensure your contact information is correct at checkout.
- ✔ Ship Your Original BCM: Carefully remove your original BCM from your ELR (typically located in the right-hand cowl or engine compartment area) and ship it to us.
- ✔ We Handle the Programming: Upon receipt, our technicians will professionally clone all the necessary data from your old module to your new one. This process typically takes 1-2 business days.
- ✔ Receive Your Ready-to-Install Module: We ship the newly programmed BCM back to you. You’ll receive tracking information once it’s on its way.
- ✔ Installation: Disconnect the negative battery terminal. Carefully install the replacement BCM, ensuring all connectors are securely seated. Reconnect the battery.
- ✔ Final Checks: Start the vehicle and test all body functions (lights, locks, windows, etc.). Note the post-installation procedures below, as some relearns may be necessary.
Important Post-Installation Information
While our goal is a seamless plug-and-play experience, some vehicle systems may require recalibration after the BCM is replaced. This is normal for modern vehicles. Key procedures to be aware of include:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for your specific vehicle.

Frequently Asked Questions
How does the mail-in cloning service work?
How does the mail-in cloning service work?
After you purchase, we’ll provide a shipping address. You send us your original BCM. We then use specialized equipment to read the vehicle-specific data from your module and write it onto the replacement unit we provide. We then ship the programmed replacement back to you, ready to install.
Do I need to program this module myself?
No. The entire point of our service is to handle the programming for you. The 2014-2016 ELR BCM you receive will be pre-programmed with your car’s data, making the installation plug-and-play and saving you a trip to the dealership.
Is there a core charge? Do I get my old module back?
There is absolutely no core charge or deposit required. We need your original module to perform the data cloning service. Once the service is complete, we ship the newly programmed replacement unit to you. Your original module is not returned.
What if I install it and a warning light like the airbag light comes on?
This can occasionally happen as different modules in the car re-establish communication. As noted in our post-installation guide, a simple relearn procedure, such as the ‘Setup SDM Primary Key in BCM’, may be needed. This requires a professional-grade scan tool but is a quick procedure for any qualified mechanic.
How do I know if the BCM is really the problem?
A failing BCM typically causes multiple, seemingly unrelated electrical issues. The best way to be certain is with a proper diagnosis from a qualified technician using a scan tool that can communicate with the BCM and check for specific fault codes (like U-codes).
