Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you battling frustrating electrical gremlins in your Cadillac, Buick, or Chevy? Intermittent power windows, flickering lights, malfunctioning door locks, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of confusing and unpredictable problems. This isn’t just an annoyance; it can impact your vehicle’s security and safety. We offer a reliable, cost-effective solution with this professionally programmed Body Control Module.
Forget about expensive dealership visits and the complexities of programming a new module from scratch. Our unique service simplifies the entire process. After you place your order, we’ll coordinate with you to ship your original BCM to our facility. Our expert technicians will then transfer—or ‘clone’—all the critical vehicle-specific data from your original module to this replacement unit. This ensures that the replacement BCM is a perfect digital match for your car, retaining all its original settings and security information. We then ship the ready-to-install module back to you, making the repair as simple as swapping the part. This is the most direct path to fixing your 2014-2016 ELR Body Control Module issues and getting your car back to 100%.
A Technician’s Notebook: The Case of the Confused Cadillac
A few months back, a 2016 Cadillac SRX came into the shop with a laundry list of bizarre symptoms. The owner reported the interior lights would stay on, the driver’s side window wouldn’t respond, and the remote key fob worked only sporadically. Diagnostics showed a flood of communication error codes (U-codes) pointing to the BCM. A physical inspection of the original module revealed no obvious damage. However, by testing the board’s internal circuits, we confirmed a microprocessor fault. Instead of a costly new module and hours of programming at the dealer, we used our cloning service. The customer shipped us their faulty BCM, we transferred the data, and sent the programmed replacement back. The install took them less than an hour, and every single electrical issue was resolved instantly. It’s a perfect example of how this service saves both time and money.
Symptoms of a Failing Body Control Module
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights) flicker, stay on, or won’t turn on.
- ✔ The security system or alarm malfunctions, sometimes preventing the car from starting.
- ✔ Dashboard warning lights appear randomly, especially for systems like ABS or Airbags.
- ✔ Communication Diagnostic Trouble Codes (DTCs) are present, such as U0140, U0155, or other U-series codes indicating a loss of communication.
- ✔ The horn honks unexpectedly or doesn’t work when pressed.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2014-2016 Cadillac ELR, the Body Control Module is typically located in the right-hand (passenger side) cowl area. For other models, refer to the fitment list below for its general location (e.g., LH dash, LH kick panel).
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the module. Press the release tabs firmly to avoid damaging them. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your pre-programmed replacement BCM in the same location and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition on and test all body functions—windows, locks, lights, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Information
While our programming service makes this a near plug-and-play repair, some vehicle systems may require a recalibration after the new 2014-2016 ELR Body Control Module is installed. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the airbag system with the BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and to prevent issues with the traction control or stability control systems.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

How does this programming service work?
How does this programming service work?
It’s simple. After your purchase, we will contact you with instructions to ship your original BCM to us. We then transfer its unique data to the replacement module. This ‘cloning’ process ensures the replacement is 100% compatible with your vehicle’s existing systems, including keys and security. We then ship the ready-to-install module back to you.
Do I need to send my original BCM?
Yes, sending your original BCM is required. This is how we extract the vehicle-specific programming that is essential for the replacement module to function correctly in your car without needing a trip to the dealer.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after we have completed the programming service on the replacement unit.
Will this fix my car not starting?
A faulty BCM can definitely cause a no-start condition, often related to the vehicle’s anti-theft or security system. If the BCM is the root cause of the problem, this pre-programmed module will resolve the issue.
What tools do I need for the installation?
Typically, you will only need basic hand tools like a socket set or screwdriver to access and remove the BCM. No special programming tools are required for the installation itself, as we handle all the programming for you beforehand. However, a professional scan tool may be needed for post-install procedures like the airbag system sync.
