Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM Solution
Are you battling bizarre electrical issues in your 2015-2016 Chevrolet Impala or other compatible GM vehicle? From flickering dash lights and erratic power windows to a car that refuses to start, a failing Body Control Module (BCM) can turn your daily driver into a source of constant frustration. As the central command for your vehicle’s comfort and convenience features, a faulty BCM can wreak havoc. In my 20+ years of diagnostics, I’ve seen these modules cause some of the most confusing symptoms, often leading to misdiagnosis and expensive, unnecessary repairs. This isn’t just a part; it’s the solution to restoring order and reliability to your car.
We offer a simple, effective, and affordable alternative to the dealership. Instead of towing your vehicle and paying steep programming fees, our service provides you with a fully programmed 2015-2016 Impala BCM that’s ready for installation right out of the box. We achieve this through a professional cloning service: you simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to a replacement unit. This process ensures seamless integration with your vehicle’s existing systems, making the repair as straightforward as possible.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a failing BCM is a likely culprit. I’ve seen these issues countless times in the shop, often starting intermittently before becoming a constant problem.
- ✔ Unresponsive or malfunctioning power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up, causing alarm faults or preventing the engine from starting (Security light on).
- ✔ The radio or infotainment system randomly turning on or off.
- ✔ Dashboard warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, such as U0140, U0155, or other ‘U’ codes, indicating a loss of communication with the BCM.
- ✔ A complete no-start condition where the starter doesn’t even click.
Case Study: The Elusive Electrical Gremlin
A customer brought in a 2015 Sierra 1500 with a problem that had stumped two other shops. The power locks would cycle randomly while driving, the dome light would flicker, and occasionally the truck wouldn’t start. They had already replaced the battery and alternator to no avail. After connecting my scan tool, I noticed intermittent communication drops across the low-speed CAN bus network. The data pointed directly to the BCM. Instead of a complex and costly rewiring job, we performed a BCM clone. By transferring the data from his original, failing module to our replacement, we solved all the issues in one shot. The customer was back on the road the next day, saving hundreds compared to a dealership visit. This is the power of a proper diagnosis and a pre-programmed module.
A Straightforward Guide to Your BCM Replacement
Our mail-in programming service is designed to be simple and get you back on the road quickly. Here is the process from start to finish:
- Purchase This Service: Complete your order online. Ensure your contact information is accurate, as we will reach out to coordinate the next steps.
- Remove Your Original BCM: Carefully disconnect your vehicle’s negative battery terminal. Locate and remove the original BCM. Its location varies by model (e.g., under the steering column in a Sierra, on the LH dash in an Impala).
- Ship Us Your Module: Securely package your original BCM and ship it to us. We will provide you with the shipping address after your purchase.
- We Handle the Programming: Once we receive your module, our technicians will perform a full data transfer to the replacement BCM. This ensures all your vehicle’s specific settings are retained.
- Receive & Install: We ship your newly programmed BCM back to you, typically within one business day of receiving your original. Installation is the reverse of removal. Reconnect your battery, and you’re ready to go!
Important Post-Installation Information
In most cases, this is a true plug-and-play repair. However, due to the complexity of modern vehicle systems, some models may require a simple relearn procedure. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional bi-directional scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some vehicles, a recalibration of the brake pedal position sensor might be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any part of the process.

Frequently Asked Questions
How does the mail-in programming service work?
After you purchase, we’ll contact you with instructions to ship your original BCM to us. We then clone its data to a replacement module and ship it back to you, ready for installation.
Do I need to get this programmed by a dealer?
No. Our cloning service makes this a plug-and-play part. All the necessary vehicle-specific programming is done by us before we ship it to you, saving you time and money.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal failure, we can still extract the necessary data. If for some reason your module is unreadable, we will contact you to discuss options, which may include a full refund.
Is there a core charge for this part?
No, there is no core charge. You are free to keep your original module after our service is complete.
Will this fix my specific problem?
This BCM will correct issues directly caused by a faulty module. If you’re experiencing symptoms like erratic lights, power accessory failure, or security system faults, this is a very common solution. Proper diagnosis is always recommended.
How do I find the part number on my BCM?
The part number is printed on a white label directly on the BCM’s plastic housing. You will need to locate and likely remove the module to read it clearly.
