Restore Full Control Over Your Vehicle’s Electronics
Are you dealing with a vehicle that seems to have a mind of its own? Flickering dash lights, power windows that won’t cooperate, or a security system that randomly acts up are all classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable issues. In my 20+ years as a technician, I’ve seen how a single failing module can make a perfectly good car feel unreliable. This isn’t just an inconvenience; it’s a matter of function and safety.
We offer a straightforward and dependable solution: a high-quality replacement BCM, part number 22820314, that arrives at your door fully programmed for your specific vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our experts will flash the module with the latest GM-certified software and calibrations. This critical step ensures seamless integration, eliminating the need for an expensive trip to the dealership for programming. You get a part that’s ready to install right out of the box.
From the Diagnostic Bay: The Case of the Haunted Traverse
A customer brought in a 2015 Chevy Traverse with a laundry list of bizarre electrical complaints. The radio would randomly shut off, the interior dome lights would flicker while driving, and the power liftgate was completely unresponsive. They were worried about a massive wiring problem. After a quick scan, I pulled a U0140 code: “Lost Communication With Body Control Module.” This pointed directly to a BCM failure. Instead of a costly diagnostic hunt, we installed this exact VIN-programmed BCM. In less than an hour, every single electrical gremlin was gone. It’s a prime example of how this single part can be the definitive fix for a host of complex-seeming issues.
Common Signs of a Failing Body Control Module
If you’re experiencing any of the following, a failing BCM is the likely culprit. Replacing it with our Programmed GM BCM can restore proper function and peace of mind.
- ✔ Erratic power window and door lock operation.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Instrument cluster warning lights (like the security light) illuminating for no reason.
- ✔ Key fob not being recognized or intermittent remote start failure.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Installation Guide
Installing your new BCM is a manageable job for a confident DIYer or any professional mechanic. Follow these general steps to get your vehicle back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: On most compatible sedans and SUVs (like the Traverse, Acadia, Enclave), the BCM is located under the driver’s side of the dashboard. On vans (Savana, Express), it’s typically behind the center dash panel.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, remove the bolts or clips securing the module to its bracket and take it out.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect all the electrical connectors into their correct ports.
- Power Up: Reconnect the negative battery terminal. Start the vehicle and test all related functions—lights, locks, windows, horn, and wipers—to confirm the repair.
Please Note: After installation, some vehicles may require additional relearn procedures as detailed in our FAQs.

Frequently Asked Questions About Your Programmed GM BCM
Frequently Asked Questions
How does the VIN programming service work?
It’s simple. After you place your order, you’ll provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your exact model and options, then load it onto the BCM. This ensures it works correctly as soon as it’s installed.
Do I have to send my old BCM back?
No. This product comes with no core charge. You can keep your original part, saving you the time and hassle of a core return.
My airbag light came on after I installed the part. Is this normal?
In some cases, yes. If the airbag warning light is on, the BCM and the airbag’s SDM (Sensing and Diagnostic Module) need to be synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears after installation.
Why are my brake lights not working correctly?
Certain models may require a Brake Pedal Position Sensor relearn after BCM replacement. This recalibration ensures the new module accurately reads the sensor’s input for proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific procedures.
Is this a guaranteed fix for my vehicle’s electrical issues?
While this Programmed GM BCM resolves the vast majority of issues listed, proper vehicle diagnosis is key. If you’ve confirmed the BCM is the point of failure, this part is the most reliable and cost-effective solution available.
