Restore Full Functionality to Your GM Vehicle with a Plug-and-Play Solution
Are you chasing down bizarre electrical issues in your GM car or truck? Flickering interior lights, power windows with a mind of their own, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant frustration. It’s the central hub for all your vehicle’s comfort and convenience features, and when it goes, chaos ensues. Forget the dealership’s high costs and lengthy service appointments. Our professional cloning service provides a reliable, cost-effective fix by transferring your vehicle’s specific data to a replacement module, ensuring a seamless installation.
This service is designed for both seasoned mechanics and determined DIYers. You simply send us your original BCM, and we handle the complex programming. We’ll transfer the VIN, key data, and option configurations to this fully tested replacement unit. When you receive it back, it’s ready to install without needing an expensive trip to the dealer for programming. This is the most direct path to solving those frustrating electronic gremlins and getting your vehicle back to 100%. We make the process simple: after your purchase, we’ll contact you with clear shipping instructions for sending in your original module.
Case Study: A Tricky Diagnosis
A customer brought in their 2015 Silverado 1500 with a laundry list of complaints: the radio would cut out intermittently, the dome lights wouldn’t turn off, and the remote start had stopped working. They had already replaced the battery and checked all the fuses. A scan showed multiple U-series communication codes, pointing towards a network issue. In my experience, when you see a cluster of unrelated body electronic failures like this, the BCM is the prime suspect. We confirmed the BCM was failing to communicate properly. Instead of a costly new module and programming from the dealer, we used our cloning service. By transferring the data from his original BCM to a replacement, we had him back on the road the next day with all functions restored, saving him hundreds of dollars and significant downtime.
Is Your Vehicle’s BCM Failing? Watch for These Signs
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it might be time for a replacement. This 2015-2016 GM BCM is the solution.
- ✔ Erratic or non-functional power windows, locks, or mirrors.
- ✔ Instrument cluster lights flickering or warning indicators staying on for no reason.
- ✔ Remote keyless entry (RKE) or push-to-start system not working.
- ✔ Interior or exterior lights behaving unpredictably (staying on or not turning on).
- ✔ Vehicle security system faults or alarm sounding randomly.
- ✔ Communication error codes stored in the system (e.g., U0140, U0155).
- ✔ Wipers or radio operating intermittently or not at all.
A Straightforward Guide to Installation
Once you receive your pre-programmed module, installation is direct. While the BCM location varies by model (check your service manual), the general process is the same. Remember to perform this work with the vehicle off.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Depending on your model, the BCM is typically found under the driver’s side dash, near the steering column, or on a firewall/hinge pillar.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount the new, programmed BCM in the same location. Securely reconnect all electrical connectors into their correct ports.
- Reconnect Power: Reattach the negative battery terminal.
- Test All Functions: Start the vehicle and test all body functions: windows, locks, lights, radio, wipers, etc., to confirm the repair is successful.
- Post-Install Checks: In some cases, an airbag light or brake system warning may appear. Procedures like an Airbag System Sync or Brake Pedal Position Relearn may be needed using a professional scan tool. This is not always required but is a possibility.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to our facility. 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 BCM back to you, typically within 1-2 business days.
Do I need to send my keys or other modules?
No, you only need to send us your original Body Control Module. All the necessary key data and security information is stored within the BCM itself, so we don’t need your keys or any other parts from your vehicle.
Is there a core charge?
No, there is no core charge for this service. You can keep your original, non-functional module after we have completed the data transfer.
What if my original BCM is badly damaged or won’t communicate?
In most cases, even with internal faults, we can still retrieve the necessary data. If your module has severe physical or water damage, please contact us before ordering. We can assess the likelihood of a successful data transfer.
Will I need to perform any procedures after installation?
Because this 2015-2016 GM BCM is cloned, it’s typically plug-and-play. However, on some models, you may need to perform a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light is on, or a ‘Brake Pedal Position Relearn’. These require a professional-grade scan tool but are not always necessary.
