Restore Your Truck’s Brain and Banish Electrical Gremlins
Are you battling bizarre electrical issues in your GM truck or SUV? Flickering lights, malfunctioning power windows or locks, a security light that won’t turn off, or even a frustrating no-start condition? These are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM goes, it can create a cascade of confusing problems.

Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specifically for your truck. This means it arrives at your door ready for installation, saving you a costly trip to the dealership and hours of diagnostic headaches. This is the most efficient way to get your 2000 Tahoe Body Control Module and other compatible GM vehicles back to factory-spec operation.
From the Diagnostic Bay
I remember a 2000 Silverado that came into my shop with the strangest symptoms. The owner said his interior lights would stay on, the radio would randomly change stations, and sometimes the horn would honk when he used the turn signal. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a dozen communication error codes (U-codes) pointing to a network failure. The culprit was a failing BCM. The internal circuits had degraded, causing it to send scrambled messages across the vehicle’s data bus. Installing a pre-programmed BCM like this one solved every single issue in under an hour. It’s a common failure point I’ve seen hundreds of times on this platform.
Is Your GM Truck Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ The radio or instrument cluster behaves unpredictably.
- ✔ Communication error diagnostic trouble codes (DTCs), such as U0140, U0155, or U0100.
- ✔ The horn sounds at random intervals or doesn’t work when needed.
A Straightforward Guide to Installation
Replacing your 2000 Tahoe Body Control Module is a manageable job for a DIYer with basic tools. The module is typically located under the driver’s side of the dashboard.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most of these trucks and SUVs, you’ll find it mounted to the left of the steering column, often behind a lower dash panel.
- Remove Connectors: Carefully press the release tabs on each of the electrical connectors and pull them straight out from the module. There are usually three or four multi-colored connectors.
- Unbolt the Module: Remove the bolts or screws holding the BCM bracket in place and carefully pull the old module out.
- Install the New BCM: Mount your new, pre-programmed module in the same location, secure it, and plug in the electrical connectors until they click firmly 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.
Important Post-Installation Steps
Because this module is central to many systems, a couple of additional procedures may be required after installation:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure your brake lights and traction control system function correctly.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s specific VIN before shipping. It arrives ready to be installed, though some minor post-install relearn procedures may be necessary depending on your vehicle.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We make it simple: there is absolutely no core charge on this module. You can keep your old part.
Where is the BCM located on my 2000 Tahoe?
The 2000 Tahoe Body Control Module is typically found under the dashboard on the driver’s side, to the left of the steering column.
What happens if my airbag light comes on after installation?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag module. This requires a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part that has been programmed with the latest software for your vehicle, ensuring reliable performance and perfect fitment.
What information do you need from me?
After you place your order, we will need you to provide your 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific vehicle options.
