Tired of Bizarre Electrical Problems in Your GM Vehicle?
As a technician with over two decades of experience, I’ve seen it all: dashboards lighting up unexpectedly, power windows with a mind of their own, and vehicles that refuse to start due to a security system fault. More often than not, the culprit is a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an inconvenience; it can be a serious safety concern.
Forget the expensive dealership visit and the hassle of finding a shop to program a new module. We offer a direct, reliable solution. This is a replacement GM BCM 22820314 that comes fully programmed to your vehicle’s specific VIN. We load the latest GM software updates before it even leaves our facility, ensuring it integrates seamlessly with your vehicle’s systems. It’s the straightforward fix you’ve been looking for.
A Technician’s Notebook: The Case of the Confused Traverse
A customer brought in a 2014 Chevy Traverse last month with a list of complaints that seemed endless. The radio would turn off, the liftgate wouldn’t open, and the “Service Stabilitrak” light was on. They had already replaced the battery, but the problems persisted. After hooking up my scan tool, I found a slew of U-codes (communication errors) all pointing back to one source. The BCM was failing intermittently, causing chaos on the vehicle’s data network. A replacement was the only fix. This pre-programmed GM BCM 22820314 is the exact solution that gets vehicles like that Traverse back to perfect working order without the dealership’s high programming fees.
Common Signs of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ Warning lights such as “Service Stabilitrak,” “Service Traction Control,” or ABS lights appear on the dash.
- ✔ The horn may sound randomly or not work at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication failures, like U0140, U0155, or other U-codes.
- ✔ The air conditioning or climate control system behaves unpredictably.
Your Straightforward BCM Installation Guide
Replacing the BCM is a manageable job for a confident DIYer. The module is typically located under the driver’s side dashboard or behind the center console, depending on your model.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On models like the Traverse, Acadia, and Enclave, it’s usually on the left-hand (driver’s) side of the dash. For Express and Savana vans, it’s often in the center dash area.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old BCM and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions—lights, locks, windows, radio, etc.—to confirm the repair.
Important Post-Installation Information
Because this GM BCM 22820314 is pre-programmed, most vehicles will be ready to go immediately. However, in some cases, additional system-to-system handshakes are required:
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag module and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure the brake lights and traction control system function correctly. This is also performed with a scan tool.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What does ‘VIN-Programmed’ mean?
It means we use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the exact software and calibrations your car needs. This eliminates the need for a dealership to program the module after installation, saving you hundreds of dollars.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Will this fix my ‘Service Stabilitrak’ warning?
A failing BCM is a very common cause of this warning light, as it disrupts communication with the brake and steering systems. While other issues can cause this light, if you’re also experiencing other electrical problems, a faulty BCM is the most likely culprit.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s VIN. We cannot ship your order until we receive the VIN, as programming is a required step.
Is this hard to install myself?
For someone with basic mechanical skills and tools, it’s generally a straightforward process. The main challenge is accessing the module, which is usually under the dashboard. Please review our installation guide and assess your comfort level before starting.
Will I definitely need a scan tool for relearn procedures?
Not always. Many vehicles will operate perfectly after installation. The relearn procedures for the airbag or brake pedal sensor are only required if you experience a specific warning light (like the airbag light) after the new BCM is installed.
