Restore Full Electrical Function to Your 2000 GM SUV
Are you battling frustrating electrical problems in your 2000 Chevrolet Suburban, Tahoe, or GMC Yukon? Flickering lights, unresponsive power windows, a malfunctioning security system, or even a vehicle that refuses to start can often be traced back to a single component: a failing Body Control Module (BCM). This vital computer acts as the central hub for your truck’s body electronics. When it fails, it can create a cascade of confusing and unpredictable issues. This replacement BCM, part number 16257155, is the definitive solution to restore your vehicle’s reliability and functionality.
Unlike sourcing a used module from a junkyard, which would require expensive dealer programming, our BCMs arrive at your doorstep pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash the unit with the latest software updates from General Motors, ensuring optimal performance and compatibility. This plug-and-play approach eliminates the need for a tow to the dealership and costly diagnostic fees, saving you significant time and money. Simply provide us with your VIN during checkout, and we handle the complex programming for you.
Expert Pro Tip
Before condemning your BCM, always perform a thorough check of your vehicle’s battery and primary ground connections. A weak battery, loose terminals, or a corroded ground strap (especially the one from the engine block to the chassis) can cause low voltage conditions that mimic the symptoms of a faulty BCM. A simple check can sometimes save you the cost of a replacement part.
Is Your 2000 Suburban BCM Failing?
A faulty Body Control Module can manifest in numerous ways, often seeming like multiple unrelated problems are happening at once. If your truck is experiencing several of the following symptoms, a failing BCM is the most likely culprit.
Common Failure Symptoms:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (lights staying on or not turning on).
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Radio or climate control systems functioning incorrectly.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Inaccurate gauge readings on the instrument cluster.
A True Plug-and-Play Solution
This isn’t just a replacement part; it’s a complete, hassle-free repair solution. The key is our professional, VIN-specific programming service. When you order, we take your truck’s VIN and configure the module to match its exact factory options and settings. This ensures that every feature—from the power seats to the keyless entry—works precisely as it did from the factory. This 2000 Suburban BCM is a direct-fit replacement for the original unit, making installation straightforward for any DIY mechanic or professional technician. The module is located under the driver’s side of the dashboard for easy access.
Installation and Post-Install Procedures
While the module is designed for a simple swap, some vehicles may require minor post-installation steps to fully sync with other onboard systems. Please be aware of the following potential procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the BCM and the airbag system’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary. This procedure can also be completed with a capable diagnostic tool.
We believe in making your repair as simple as possible, which is why there is no core charge for this module. You can keep your original part without the hassle of shipping it back.

Frequently Asked Questions
What does a Body Control Module actually do?
The BCM is a computer that supervises and controls many of the non-engine-related functions in your vehicle. This includes power windows, locks, lights, the alarm system, interior chimes, and communication between various electronic modules. Think of it as the central nervous system for your truck’s body electronics.
Is this BCM truly plug-and-play?
Yes, for the vast majority of vehicles. Because we program it to your VIN before shipping, it will control all the basic functions immediately upon installation. However, as noted, some vehicles may require a simple sync procedure for the airbag or brake systems, which needs a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function correctly in your vehicle.
What happens if my airbag light is on after installation?
This is a known possibility and does not indicate a faulty part. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to turn off the light.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep, discard, or recycle your original module at your convenience without any extra fees or hassle.
