Tired of Unpredictable Electrical Problems in Your Cadillac?
If your 2014-2016 Cadillac ELR is plagued by baffling electrical issues—power windows with a mind of their own, flickering interior lights, unresponsive door locks, or strange warning messages on your dash—you’re likely dealing with a failing Body Control Module (BCM). As an expert technician with over two decades of experience, I’ve seen how a faulty BCM can turn a sophisticated vehicle into a source of daily frustration. The BCM is the central command for your car’s body electronics, and when it fails, chaos ensues.
Forget the expensive trip to the dealership and the hassle of vehicle-side programming. We offer a streamlined, reliable solution. This is a professionally tested BCM that comes fully programmed through our mail-in cloning service. Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. We will transfer all the critical data from your original unit to this replacement, making it a true plug-and-play component for your vehicle. This process ensures all your car’s original features and security settings are perfectly preserved.
Case Study: A Tricky Diagnosis
A 2015 Cadillac ELR came into the shop with a complaint that was driving the owner crazy: the radio would randomly shut off, the driver’s side power window wouldn’t work, and the anti-theft light would stay on, sometimes causing a no-start. The owner had already replaced the battery and checked fuses. Diagnostics showed several communication error codes (U0140, U0155). Instead of just throwing parts at it, we isolated the BCM. These intermittent, multi-system faults are a classic sign of internal BCM failure. By providing a cloned ELR Body Control Module, we restored all functions in one go, without the car ever having to sit at a dealership for programming. It’s a precise fix for a complex problem.
Common Signs of a Failing BCM
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your solution:
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The security system acting up, causing intermittent no-start conditions.
- ✔ False warnings on the instrument cluster (e.g., “Service Theft Deterrent System”).
- ✔ Diagnostic Trouble Codes (DTCs) related to communication loss, such as U0140.
- ✔ Inconsistent operation of heating and A/C blower controls.
Your Straightforward Installation Path
Our cloning service makes the physical installation simple. Once you receive the programmed module from us, follow these general steps. The BCM in your ELR is located in the right-hand cowl area.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Access the BCM at its mounting location. This may require removing a kick panel or trim piece.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Note their orientation. Then, unbolt and remove the module from its bracket.
- Install the New Module: Mount your new, pre-programmed ELR Body Control Module in place and securely reconnect all electrical connectors.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair. Refer to the post-installation notes below.
Important Post-Installation Information
While our programming makes this a plug-and-play repair, some vehicle systems may require a relearn procedure after the BCM is replaced:
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
