Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you dealing with bizarre and frustrating electrical issues in your Cadillac ELR or other GM vehicle? One moment the power windows work, the next they don’t. Maybe your dashboard is lit up with random warning lights, or the car refuses to start for no apparent reason. These are classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can wreak havoc. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a streamlined and reliable solution. This listing is for a replacement Body Control Module, programmed specifically for your vehicle using the data from your original unit. This cloning service ensures that the replacement you receive is 100% plug-and-play, preserving your car’s original settings, key fob programming, and security information.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Chevy Malibu with a complaint that stumped two other shops. The radio would turn on by itself, the interior lights would flicker, and occasionally the car wouldn’t recognize the key fob. There were no consistent trouble codes, just a few intermittent communication errors (U-codes). After checking the main power and ground connections, I focused on the BCM. On the surface, the module looked fine. However, by monitoring live data streams, I saw erratic voltage outputs to the affected circuits. We performed our cloning service onto a replacement module, and within an hour of installation, all the ghost-like electrical problems were gone. This is a perfect example of how a failing BCM can cause chaos without leaving obvious clues.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. This is especially true if multiple symptoms appear at once.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up, causing no-start conditions or sounding the alarm randomly.
- ✔ Instrument cluster warning lights (like ABS, Airbag, or Traction Control) illuminating without a clear cause.
- ✔ Key fobs not being recognized by the vehicle.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
Your Straightforward Installation Guide
Our cloning service makes the physical replacement simple. Once you receive the programmed module from us, follow these general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the 2014-2016 ELR, the BCM is typically located in the right-hand cowl area. For other models, refer to the fitment list below for its general location (e.g., LH kick panel, RH dash).
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
- Power Up: Reconnect the negative battery terminal.
- Test Functions: Start the vehicle and test all body-related functions—windows, locks, lights, wipers, and radio—to confirm the repair was successful.
Important Post-Installation Notes
While our goal is a seamless plug-and-play experience, some vehicle systems may require a quick recalibration after the BCM is replaced. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the BCM with the airbag module and turn off the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control performance.
Disclaimer: These procedures can vary. We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
Frequently Asked Questions
How does this mail-in programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. We then ship the ready-to-install module back to you. This process ensures all your vehicle’s specific settings are retained.
Is this really plug-and-play? Will I need a dealer?
Yes, because we clone your original module’s data, the replacement BCM is fully programmed for your specific vehicle. This eliminates the need for any additional programming from a dealership, saving you significant time and money.
What if my original BCM is completely dead or water damaged?
In many cases, even if the BCM is non-functional, we can still retrieve the necessary data from the memory chip. Please contact us before purchasing if your module has severe physical or water damage so we can assess the likelihood of a successful data transfer.
Do I need to send my keys or other modules?
No, you only need to send us your original Body Control Module. Since we are cloning the data that already contains your key information, your existing keys will work perfectly with the new module.
How long does the programming service take?
We pride ourselves on a fast turnaround. The programming is typically completed and the module is shipped back out within 1-2 business days of us receiving your original BCM.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module after the service is complete.
