Is Your GM Truck or SUV Acting Possessed?
Are you dealing with a frustrating mix of electrical issues in your Tahoe, Silverado, or Yukon? Flickering dashboard lights, power windows and locks with a mind of their own, a security system that randomly acts up, or a battery that drains for no reason are all classic signs of a failing Body Control Module (BCM). These problems aren’t just annoying; they can compromise your vehicle’s reliability. Stop chasing electrical gremlins and get the definitive, hassle-free solution.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of confusing problems. You might be experiencing:
- Intermittent or non-working power windows, door locks, and interior lights.
- Erratic instrument cluster behavior or warning lights that won’t turn off.
- Problems with the radio or climate control system.
- Security system faults or a no-start condition due to Passlock issues.
- Communication error codes (U-codes) when scanning the vehicle.
This replacement Body Control Module is the answer. It arrives programmed specifically to your vehicle’s VIN, ensuring it communicates perfectly with your truck’s other systems right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.

- ✔ VIN-Programmed for Your Vehicle: We flash the module with the latest GM software using your VIN. This ensures compatibility and proper function of all your vehicle’s specific options.
- ✔ Plug & Play Installation: Because it’s pre-programmed, installation is straightforward. Simply disconnect the old module and connect the new one. No dealer visit required.
- ✔ Restores Full Functionality: Get your power accessories, security system, and instrument cluster working reliably again.
- ✔ No Core Charge: You don’t need to send your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.
- ✔ Peace of Mind Included: This unit is backed by our one-year replacement warranty.
An Expert’s Note on GM BCMs
“On these early 2000s GM trucks and SUVs, the BCM is the central hub for almost all interior electronics. It’s not just a simple fuse box; it’s a computer that manages everything from the dome light to the anti-theft system. That’s why VIN-programming isn’t just a convenience—it’s a necessity. Without the correct programming for your specific RPO codes (Regular Production Options), you could end up with new problems, like windows that don’t work or a persistent security light. We handle that complex step for you, so the 2000 Tahoe BCM you receive is truly ready for your vehicle.”
Important Post-Installation Information
While this module is designed for a simple installation, some vehicles may require one or two final synchronization steps. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on 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 module.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the programming process work?
It’s simple. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this VIN to download the correct software and calibration files from GM’s database and flash them onto the module before it ships. This ensures it’s a perfect match for your truck’s factory options.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. The BCM is typically located under the driver’s side dashboard. It involves removing a few trim panels and disconnecting electrical connectors. The key benefit of our product is that the difficult part—the computer programming—is already done for you.
What happens if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A repair shop with a professional-grade bidirectional scan tool (like a Snap-on, Autel, or a GM Tech 2) can perform the “Setup SDM Primary Key in BCM” procedure in a few minutes to resolve this.
Do I really not have to send my old part back?
That’s correct. There is no core charge or need to return your original module. This saves you the time, cost, and hassle of shipping a part back to us.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many systems, a ‘Service 4WD’ message is often related to the Transfer Case Control Module (TCCM), the encoder motor, or the switch on the dash. A failing BCM can sometimes cause communication errors that trigger other warnings, but you should diagnose the 4WD system specifically if that is your primary issue. This 2000 Tahoe BCM is the correct fix for body-related electrical functions.
