Restore Your GM Truck’s Electrical System with a Plug-and-Play BCM

Are you chasing electrical gremlins in your 2012-2014 Chevy Tahoe, Silverado, or other GM truck? Flickering lights, malfunctioning power windows, a radio that has a mind of its own, or random warning messages on the dash are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. In my 20+ years of diagnostics, I’ve seen these modules cause everything from simple annoyances to no-start conditions that leave drivers stranded.

Forget the expensive dealership visit and the hassle of scheduling programming. We offer a direct, reliable solution. This BCM, compatible with part numbers 22737275, 22846365, and 22846364, comes fully programmed to your vehicle’s specific VIN. Just provide us with your VIN at checkout, and our technicians will flash the module with the latest GM software updates before it even leaves our facility. This ensures it’s ready for installation right out of the box, restoring function and communication between your vehicle’s critical systems.

Signs Your GM Truck’s BCM is Failing

The BCM is the nerve center for dozens of components. If you’re experiencing any of these issues, your BCM is the likely cause:

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
• ✔ The security system light stays on, preventing the vehicle from starting.
• ✔ Warning lights on the dashboard such as ‘Service StabiliTrak’ or ‘Service 4WD’.
• ✔ Inconsistent or non-working radio and climate control functions.
• ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1325.
• ✔ Horn sounding unexpectedly or not working when pressed.

Your Straightforward BCM Installation Guide

Installing your new BCM is a manageable job for a confident DIYer. It’s typically located under the driver’s side of the dashboard, near the steering column.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
2. Access the Module: You will likely need to remove the lower dash panel or knee bolster to gain access to the BCM. This is usually held in by a few screws or clips.
3. Identify and Disconnect: Locate the BCM. Before unplugging, take a picture of the connector locations and colors to make reassembly foolproof. Carefully release the locking tabs on each electrical connector and pull them straight out.
4. Remove the Old BCM: The module itself is typically held in place by a few small bolts or plastic clips. Remove them and slide the old BCM out of its mounting bracket.
5. Install the New BCM: Slide your new, pre-programmed BCM into the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
6. Final Steps: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle to test all functions (lights, windows, radio, etc.).

Important Post-Installation Notes

While our VIN programming handles the vast majority of the setup, some GM vehicles may require a simple relearn procedure for specific systems to communicate with the new BCM. This is normal.

• Airbag System Sync: If the airbag (SRS) light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This syncs the new BCM with the airbag module and requires a professional-grade scan tool.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and StabiliTrak function.
• No Core Charge: You are not required to return your old module. There is no core charge or deposit associated with this purchase.

Disclaimer: Vehicle systems vary. Always have a factory service manual available for your specific model or consult with a certified technician if you are unsure about any procedure.
