End the Electrical Chaos: A Reliable Fix for Your GM Vehicle
If you’re dealing with bizarre and frustrating electrical issues in your 2014-2017 Chevrolet Caprice or another compatible GM vehicle, you’ve likely discovered the culprit is the Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen it all: lights flashing for no reason, power windows with a mind of their own, security system lockouts, and even no-start conditions that leave you stranded. These aren’t random glitches; they’re classic signs of a failing BCM, the central command center for your vehicle’s body electronics.
Simply buying a new or used BCM from the dealer or a junkyard won’t solve the problem. It must be programmed specifically to your vehicle’s VIN and options, a costly and time-consuming process. Our solution bypasses that headache entirely. We offer a professional cloning service for your 2014-2017 Caprice BCM. You send us your original module, and we transfer all of its critical data—including VIN, mileage, and key information—to this fully tested replacement unit. The result? A true plug-and-play module that restores full functionality without any additional programming required.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 GMC Sierra 2500 with a complaint that was driving him crazy: the radio would randomly turn off, the driver’s side power window would stop working, and he’d occasionally get a “Service StabiliTrak” message. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of U-codes (communication errors), specifically U0140, pointing to a loss of communication with the BCM. Instead of a complete failure, the BCM was failing intermittently, corrupting the data network. By cloning his original module to our replacement, we solved all the electrical gremlins in one shot, saving him hundreds compared to a dealership visit.
Is Your Vehicle Exhibiting These BCM Failure Signs?
A failing BCM can cause a wide range of symptoms that seem unrelated. If you’re noticing any of the following, your BCM is the likely cause:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Instrument cluster gauges sweeping, flickering, or going dark.
- ✔ “Service Theft Deterrent System” message and potential no-start conditions.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-series codes.
- ✔ Inconsistent A/C and climate control operation.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is designed to be a simple swap. While the exact location can vary, it’s typically found under the driver’s side dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most listed models, the BCM is located under the steering column or on the driver’s side firewall/kick panel area. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, windows, locks, wipers, and horn to confirm the repair.
Important Post-Installation Information
In some cases, minor follow-up procedures may be needed to ensure all systems are perfectly synced.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control functionality.
- No Core Required: We make it simple. There is no core charge, so you can keep your original module.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified automotive technician if you are unsure about any step.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we extract the essential software and vehicle-specific data (like VIN, security info, and options) from your original BCM and transfer it directly to a replacement module. This makes the new module a perfect electronic match for your vehicle, eliminating the need for expensive dealership programming.
Do I need to program this BCM after I receive it?
No. Because we clone your original data, this module arrives ready for installation. It is a true plug-and-play solution, designed to save you time and money.
How does the process work?
After you place your order, we will contact you with simple instructions and a shipping address. You will need to ship your original BCM to us. Once we receive it, we perform the cloning service and ship your ready-to-install replacement BCM back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is causing major issues, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), please contact us before ordering to discuss options.
Will this fix my check engine light?
This BCM will resolve issues and diagnostic trouble codes (DTCs) directly related to the Body Control Module, such as communication codes (U-codes). It will not fix codes related to the engine, transmission, or other separate vehicle systems.
