Is Your Cadillac ELR Experiencing Strange Electrical Issues?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your power windows and locks to the interior lighting, security system, and even communicates with other critical modules. When the BCM begins to fail, it can create a cascade of confusing and frustrating problems that can seem unrelated. If you’re dealing with unpredictable electrical gremlins, a faulty BCM is often the culprit.
This is not just a replacement part; it’s a complete, hassle-free solution. We offer a professionally programmed 2014-2016 ELR Body Control Module that is ready for installation upon arrival. Our unique cloning service transfers all the essential data from your original module to this replacement unit, ensuring a seamless integration with your vehicle’s existing systems. This process bypasses the need for expensive dealership programming and complex setup procedures.
From the Diagnostic Bay
We had a 2015 Cadillac SRX come in with a complaint that was driving the owner crazy. The interior lights would flicker randomly, the radio would sometimes not turn on, and occasionally, the alarm would go off for no reason. They had already replaced the battery, but the problems persisted. After running diagnostics, we found no specific fault codes pointing to a single component, a classic sign of a network communication issue. We traced the problem to the BCM, which was intermittently failing and sending corrupt data across the vehicle’s network. By providing a cloned BCM, we were able to restore all functions perfectly without the customer having to pay for key reprogramming or other dealer-specific initializations. It’s a perfect example of how a failing BCM can manifest as multiple, seemingly unrelated issues.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security system or keyless entry system malfunctioning.
- ✔ Dashboard warning lights appearing randomly.
- ✔ Issues with the radio, climate control, or other interior accessories.
- ✔ A parasitic battery drain that kills your battery overnight.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Why Choose Our Programmed 2014-2016 ELR Body Control Module?
Replacing a modern BCM isn’t as simple as swapping parts. The module is tied to your vehicle’s VIN and security system. A standard used module from a junkyard will not work without extensive, and often expensive, programming with dealership-level tools. Our cloning service makes this a true plug-and-play repair. All the data that makes your car unique is transferred, preserving original key functionality and avoiding anti-theft system conflicts.
Post-Installation Requirements
While our programming handles the critical setup, some GM vehicles may require minor recalibration procedures after installation. These are simple for any professional technician with a capable scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper operation of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
What does this BCM programming service do?
Our service transfers the vital information—like VIN, key data, and vehicle options—from your original BCM to the replacement unit. This makes the new module plug-and-play, avoiding the need for costly dealership programming.
How long does the service take?
We typically program and ship the replacement module within 1-2 business days of receiving your original BCM. Return shipping time will depend on your location.
What if my original BCM is not communicating or is water damaged?
In many cases, even if the BCM is non-communicative or has physical damage, we can still recover the necessary data. Please contact us before ordering if you suspect your module is severely damaged.
Will I need to have my keys reprogrammed?
No. Because we clone the data from your original module, the replacement BCM will recognize your existing keys, saving you time and money.
Is this a difficult part to install?
The physical installation is straightforward for someone with moderate mechanical skill. The BCM is typically located in the driver’s or passenger’s kick panel or cowl area. However, post-installation procedures like an airbag sync may require a professional scan tool.
