Is Your GM Vehicle Plagued by Electrical Gremlins?
If your 2015 Cadillac Escalade, Sierra, Silverado, or other compatible GM vehicle is experiencing bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from power windows and locks to interior lighting, the security system, and even communication between other critical modules. When it fails, it can create a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or not working.
- ✔ The horn or windshield wipers activating randomly without input.
- ✔ Key fobs failing to lock or unlock the doors, or the security system acting erratically.
- ✔ Warning messages on the dashboard such as “Service Security System” or “Service Stabilitrak.”
- ✔ Intermittent no-start or no-crank conditions where the engine won’t turn over.
- ✔ Inaccurate fuel gauge or other instrument cluster malfunctions.
We had a 2015 GMC Sierra 2500 in the shop that was driving the owner crazy. The dome lights would flicker at random, the radio would shut off, and occasionally it wouldn’t start. The battery and alternator tested fine. After checking the main network, we noticed communication dropouts originating from the BCM. Upon removal, we found faint traces of water intrusion from a leaky windshield seal that had slowly damaged the BCM’s circuit board. A cloned BCM solved all the issues instantly, saving the customer from a costly and complex diagnostic journey at the dealership.
The Easiest Solution: A Plug-and-Play Programmed BCM
Forget expensive dealership visits, towing fees, and the headache of programming a new module from scratch. Our professional mail-in cloning service provides you with a fully programmed, plug-and-play replacement BCM. We transfer the critical data—including your vehicle’s VIN, security information, and specific options—from your original module to a replacement unit. When you receive it back, installation is as simple as swapping the part. No further programming or calibration is required.

- ✔ Send Us Your Module: Carefully package and ship your original BCM to us.
- ✔ We Program Your Replacement: Upon arrival, our technicians will professionally clone all necessary data to the replacement BCM, typically within 1-2 business days.
- ✔ Receive Your Plug-and-Play Part: We ship your original module and the ready-to-install replacement back to you. Simply plug it in and restore your vehicle’s functionality.
Post-Installation Checks for Your 2015 Escalade BCM
While our service makes this a plug-and-play repair, certain vehicle systems may require a simple synchronization procedure after the new module is installed. This is normal and can often be performed with a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) to clear the light. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function as intended.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly is a “cloning” service?
Cloning is the process of transferring all the vehicle-specific software and data from your original BCM to the replacement unit. This includes the VIN, mileage, key fob information, and vehicle options. This makes the replacement module a true plug-and-play solution.
Do I need a dealer to program this after I install it?
No. Because we clone your original data, the replacement BCM will be ready for installation right out of the box. This process completely bypasses the need for expensive dealership programming.
How long does the programming service take?
Our service is typically completed within 1-2 business days after we receive your original module. We then ship it back to you promptly, and you will receive tracking information at that time.
Will my original keys and remote fobs work?
Yes. All security data related to your keys and remotes is transferred during the cloning process. Your existing keys will work exactly as they did before, with no relearning required.
What if my original BCM is badly damaged or unreadable?
In the vast majority of cases, even with physical or water damage, our technicians can still recover the necessary data. In the rare event that your module’s data is completely unrecoverable, we will contact you immediately to discuss your options.
Is there a core charge for this part?
No, there is no core charge. We use your original module for the data transfer and then send it back to you along with the programmed replacement. You can keep your original part.
