End the Electrical Gremlins in Your GM Truck or SUV
Are you chasing bizarre and frustrating electrical problems in your Suburban, Tahoe, or Silverado? Flickering interior lights, power windows and locks with a mind of their own, or a security system that randomly acts up are all classic signs of a failing Body Control Module (BCM). This central computer is the nerve center for your vehicle’s body electronics, and when it fails, it can make your reliable truck feel unpredictable. Stop wasting time and money on incorrect diagnoses and get the definitive solution.
Common Symptoms of a Failing BCM & Your Direct Solution
If you’re experiencing any of the following, a faulty BCM is the likely culprit. This pre-programmed module is designed to be the direct, reliable fix for these issues. We handle the complex programming so you can focus on the installation.
- Intermittent or non-working power windows, door locks, or mirrors.
- Erratic instrument cluster behavior or warning lights (like the security light).
- Interior dome lights staying on or not working at all.
- Problems with the radio or climate control functions.
- The vehicle’s security system preventing it from starting.
Replacing your faulty unit with our pre-programmed 2000 Suburban 1500 Body Control Module will restore the precise, factory-intended operation of these critical systems, giving you a vehicle you can count on again.

An Expert’s Take on GMT800 Electronics
“As a technician, I’ve seen countless GMT800 platform trucks—the Silverados, Suburbans, and Sierras from this generation. They are legendary for their durability, but after two decades, their electronic modules are a common point of failure. The BCM is ground zero for the ‘weird’ electrical problems owners describe. In the past, this was a dealer-only repair due to the programming requirements. A VIN-programmed module like this one is the smartest way to perform this repair today. It saves the DIYer or independent shop hundreds of dollars and hours of hassle. It’s the exact fix needed to keep these great trucks on the road and running right.”
Important Post-Installation Information
While this 2000 Suburban 1500 Body Control Module is designed for a straightforward swap, some vehicles may require additional electronic ‘handshake’ procedures after installation. Please be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
We provide this information to ensure you have a complete picture of the repair. For the dedicated DIYer, this is a very manageable job that restores critical vehicle functions. The key is our VIN-specific programming, which handles the most difficult part of the job before the 2000 Suburban 1500 Body Control Module even ships.
Frequently Asked Questions
Do I need to send my VIN number?
Yes. Providing your Vehicle Identification Number (VIN) is mandatory. We use it to program the module with the exact software and calibrations for your specific vehicle, ensuring compatibility and proper function.
Is this a difficult part to install?
For someone with basic mechanical skills, the physical installation is straightforward. The BCM is typically located under the driver’s side dashboard. The main challenge has always been the programming, which we handle for you. Some post-install electronic procedures may be required, as noted in the description.
Will this fix my ‘Security’ light issue?
A flashing or solid security light and a no-start condition are very common symptoms of a failed BCM in these GM vehicles. This module is the correct component to fix that issue, as it controls the Passlock security system.
What tools are needed for the post-installation procedures?
Procedures like the Airbag System Sync or Brake Pedal Position Relearn require a bi-directional professional diagnostic tool (scan tool). Many local repair shops can perform these quick procedures for a small fee if you do not have access to one.
Is this compatible with my 2000 GMC Sierra?
Yes, this part is compatible with a wide range of GM trucks and SUVs from that era that use the specified service numbers (19208539, 9371990, 9385236). This includes the GMC Sierra, Yukon, Chevy Silverado, Tahoe, and more. Please check the fitment list to confirm your specific model.
