Restore Full Functionality to Your Cadillac ELR
Are you battling frustrating electrical gremlins in your 2014-2016 Cadillac ELR? Intermittent power windows, flickering lights, malfunctioning door locks, or even a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). As the central command center for your vehicle’s comfort and convenience features, the BCM’s health is critical. When it falters, it can create a cascade of confusing and unpredictable problems. This isn’t just an inconvenience; it can impact your vehicle’s security and your daily routine.
We offer a straightforward and reliable solution. Instead of facing expensive diagnostics and programming fees at the dealership, our professional cloning service provides you with a fully programmed BCM ready for installation. This service for the 2014-2016 ELR Body Control Module eliminates the need for any additional programming or key relearning, making it a true plug-and-play fix.
How Our BCM Programming Service Works
Our process is designed for your convenience. After you place your order, we will contact you with simple, step-by-step instructions to ship your original BCM to our facility. Once we receive it, our expert technicians will transfer all the essential data—including your vehicle’s specific configuration and security information—to a replacement unit. This ensures seamless integration with your ELR’s existing electronic systems. We then ship the ready-to-install module back to you, complete with tracking information. You get a fully functional BCM without the dealership hassle.
From the Diagnostic Bay: The Case of the Confused Cadillac
A few months back, a 2015 ELR came into the shop with a list of symptoms that had the owner completely stumped. The radio would randomly shut off, the passenger window wouldn’t respond, and the key fob only worked sporadically. The owner had already replaced the fob battery and checked fuses, but the issues persisted. On the scan tool, we saw a flurry of ‘U’ codes, specifically U0140 (Lost Communication With Body Control Module), pointing to a network problem. Instead of a complex wiring issue, my experience immediately pointed to the BCM itself. We performed our cloning service, and the new module resolved every single issue instantly. It’s a classic example of how a failing BCM can mimic multiple, unrelated problems.
Common Signs of a Failing BCM
If your ELR is experiencing these issues, a faulty BCM is the likely culprit. A failing module can trigger various Diagnostic Trouble Codes (DTCs), most commonly communication codes like U0140, U0155, or B-series codes related to specific body functions.
- âś” Erratic or non-working power windows, door locks, or interior/exterior lights.
- âś” Key fob not being recognized or intermittent remote functions.
- âś” Security system randomly activating or preventing the car from starting.
- âś” Warning lights on the dash, such as the “Service Vehicle Soon” indicator.
- âś” Wipers, horn, or other accessories working intermittently or not at all.
- âś” Complete no-start condition where the ignition seems dead.
Your Straightforward BCM Installation Guide
Installing your newly programmed BCM is a manageable task for a confident DIYer. For the 2014-2016 Cadillac ELR, the BCM is typically located in the right-hand (passenger side) cowl area.
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery and wait at least 10 minutes to allow all systems to power down completely.
- Locate the Module: Access the BCM by removing the necessary trim panels in the passenger-side cowl or kick panel area. Its exact position can be confirmed with a service manual.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount the replacement BCM onto the bracket and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition on (without starting the engine) and test all body functions: windows, locks, lights, wipers, and radio to confirm proper operation.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple recalibration procedure after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the BCM and the Sensing and Diagnostic Module (SDM) need to be re-synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
After you purchase, we’ll email you a prepaid shipping label and instructions. You simply package your original BCM, send it to us, and we’ll handle the rest. We transfer the data to the replacement module and ship it back to you, ready for installation.
Do I need to send in my keys?
No. Because we are cloning the data from your original BCM, all your existing keys will work seamlessly with the replacement module. No key programming is required.
Is this a guaranteed fix for my car’s problems?
This service resolves all issues directly caused by a faulty BCM. If your vehicle has been properly diagnosed with a failed BCM, this programmed module will restore its functions. It will not fix problems related to other faulty components or wiring.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
Is there a core charge for my old BCM?
No, there is no core charge. We need your original module to perform the data cloning service, but you are not required to return it after receiving the replacement.
