Is Your Vehicle Experiencing Strange Electrical Problems?
If your Chevrolet Impala, or another compatible GM vehicle, is suffering from flickering lights, malfunctioning power windows, erratic dashboard warnings, or a no-start condition, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and security systems to power locks and climate control. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues.
From the Diagnostic Bay
We once had a 2016 Silverado in the shop with a complaint of the radio turning on and off by itself and the dome lights staying on, draining the battery overnight. The owner had already replaced the battery and the radio head unit with no success. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of just selling him a new module that would require expensive dealership programming, we offered our cloning service. By transferring the data from his original, failing BCM to our replacement unit, we saved him hundreds of dollars and got his truck’s electronics working perfectly again. It’s a reminder that proper diagnosis is key, and a faulty BCM can mimic many other problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Dashboard warning lights illuminating for no reason (e.g., security, airbag, traction control).
- ✔ Interior or exterior lights not working correctly (staying on, not turning on, or flickering).
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ Horn honking randomly or not working at all.
- ✔ Key fob not being recognized or functioning intermittently.
- ✔ Climate control system behaving erratically.
The Simple, Plug-and-Play Solution: Our BCM Programming Service
Don’t pay exorbitant dealership fees for a new module and programming. Our service provides a straightforward and cost-effective solution. We supply a replacement BCM with part number 13593214 (or a compatible alternative) and transfer all the critical data from your original module onto it. This ‘cloning’ process ensures the replacement BCM is a perfect match for your vehicle’s specific configuration, including its VIN and factory-installed options.
How The Process Works:
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ We Contact You: We will reach out to you using the contact information on your order to provide shipping instructions for your original BCM.
- ✔ Ship Your Original Module: Carefully package and send your original BCM to our facility.
- ✔ We Program Your Replacement: Upon arrival, our technicians will professionally transfer all necessary data from your old module to the replacement unit.
- ✔ Receive Your Plug-and-Play BCM: We ship your original module and the newly programmed replacement back to you. Installation is as simple as swapping the units, with no further programming required.
Post-Installation Checks for Your 2015-2020 Impala BCM
While our goal is a 100% plug-and-play experience, some vehicle systems may require a quick recalibration after the BCM is reconnected. These are simple procedures that can often be performed with a high-end diagnostic 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. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) to clear the light.
- 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 do I need to send you?
You only need to ship your original Body Control Module (BCM) to us. After you place your order, we will contact you with detailed shipping instructions and the address for our facility.
Is this BCM new or used?
We use high-quality, fully tested replacement modules. Each unit is inspected and verified to be in perfect working condition before we program it with your vehicle’s data.
How long does the programming service take?
Once we receive your original BCM, the programming and testing process typically takes 1-2 business days. We then ship both your original and the newly programmed replacement module back to you.
Will I need to do any programming myself after I install it?
No, the module will arrive ready for installation. Our cloning service makes it a true plug-and-play part. In some rare cases, a simple relearn procedure like for the airbag or brake pedal sensor may be needed, as detailed in the description.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still extract the necessary data. If for some reason your module’s data is completely unrecoverable, we will contact you to discuss alternative options or provide a full refund.
