Is your 2000 GM truck or SUV plagued by frustrating electrical gremlins?
If you’re dealing with flickering lights, unresponsive power windows and locks, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of baffling and intermittent issues. This replacement Body Control Module, part number 09377486, is the definitive solution to restore your vehicle’s factory functions and reliability.
From the Diagnostic Bay
We had a 2000 Tahoe come in where the owner had spent hundreds of dollars replacing the driver’s side window motor and switch, but the window still worked intermittently. He was convinced the wiring was bad. After a quick scan, we saw communication faults with the BCM. Instead of a costly wiring chase, we installed a VIN-programmed BCM. All the power accessories, including that stubborn window, started working perfectly. It’s a classic case where the central computer, not the individual components, was the root of the problem.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing or acting unpredictably.
- ✔ The radio or instrument cluster gauges behaving strangely.
- ✔ A persistent “Service Vehicle Soon” light on the dash.
- ✔ Battery drain issues caused by the BCM not properly shutting down accessories.

Simple Installation & Post-Install Information
Installation is straightforward. The BCM is typically located under the driver’s side of the dashboard. Once installed, most functions will be immediately restored. However, please be aware of the following potential procedures:
- Airbag System Sync: If your 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 your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function as intended.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic functions not related to the engine, such as power windows, locks, lights, wipers, security system, and instrument panel gauges.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is typically simple. The BCM is usually located under the driver’s side dashboard and held in by a few bolts or clips. Since we program it beforehand, it’s designed to be a plug-and-play process, though some post-install procedures may be needed as noted.
Do I need to send my old part back?
No. This purchase does not require a core return. You can keep your original module.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and features. This ensures compatibility and proper function without needing a trip to the dealer.
What if my airbag light is on after I install the BCM?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a professional-grade diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
