Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your vehicle? Intermittent power windows, flickering lights, a malfunctioning security system, or even a no-start condition can all point to a failing Body Control Module (BCM). As the central computer for your car’s comfort and convenience features, a faulty BCM can cause a cascade of confusing problems. In my 20+ years of diagnostic work, I’ve seen how a single failing BCM can make a perfectly good car feel unreliable. This isn’t just an inconvenience; it can affect your vehicle’s security and safety systems.
We offer a straightforward and reliable fix. This is a professionally programmed Body Control Module, configured specifically for your vehicle using the data from your original unit. This cloning service eliminates the need for expensive dealership visits for programming. You simply send us your original BCM, and we transfer all the critical vehicle-specific information to this replacement module. We then ship it back to you, ready for installation. It’s the most efficient way to get your car back to 100% functionality.
A Technician’s Notebook: The Case of the Confused Cadillac
A customer brought in a 2015 Cadillac SRX with a truly bizarre set of symptoms. The radio would turn on by itself, the driver-side window wouldn’t respond, and the anti-theft light would flash randomly, sometimes preventing the car from starting. They had already replaced the battery to no avail. After hooking up my scan tool, I found a slew of communication error codes, primarily a U0140 (Lost Communication With Body Control Module). Instead of shotgunning parts, we focused on the BCM. By providing a programmed module like this one, we were able to solve all the issues in one go, saving the customer hundreds compared to the dealership quote. This is a classic BCM failure scenario.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system engaging randomly or causing a no-start condition.
- ✔ The key fob not being recognized or working intermittently.
- ✔ Warning lights on the dashboard for systems like ABS, Airbag, or Traction Control.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate Your BCM: The location varies by model. For the 2014-2016 ELR, it’s typically found in the right-hand cowl area. For other models, check the fitment list below for common locations (e.g., LH kick panel, RH dash).
- ✔ Remove the Original Module: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or lifted. Then, unbolt the module from its mounting bracket.
- ✔ Ship Us Your Module: After purchase, we will contact you with shipping instructions. Please ensure your contact information is correct. Pack your original BCM securely and send it to us.
- ✔ Install the Replacement: Once you receive the programmed module from us, simply bolt it into place and reconnect the electrical connectors. Reconnect your battery.
- ✔ Perform Post-Install Checks: Start the vehicle and verify that the original issues are resolved. Check lights, locks, and windows. See the Post-Installation Procedures section below for potential additional steps.
Important Post-Installation Procedures
While our programming makes this a plug-and-play repair for most functions, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary. Always consult your vehicle’s factory service manual or a qualified technician for detailed guidance.

Frequently Asked Questions
How does this programming service work?
It’s simple. After you place your order, we’ll provide instructions for you to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement module. We ship the newly programmed module back to you, ready for installation.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle will not work correctly because it’s programmed for that car’s specific options and security information. Our service clones your car’s unique data, making our module a true plug-and-play replacement without needing dealer tools.
Is there a core charge?
No, there is no core charge. We use your original module for data transfer only. You do not need to send it back after receiving the programmed replacement.
Will I need to program my keys again?
No. Because we clone all the data from your original module, including the security information, your existing keys will work immediately upon installation.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn, if required, must be performed with a professional-grade bidirectional diagnostic scan tool. Many local repair shops can perform these procedures for you.
How do I know if my BCM is the problem?
The most common indicators are multiple, unrelated electrical issues. For a definitive diagnosis, a qualified technician should check for communication codes (U-codes) and test power/ground circuits at the BCM connector.
