Is Your 2000 GM SUV Experiencing Strange Electrical Issues?
If your GMC Yukon, Chevy Tahoe, or Suburban is acting possessed—with flickering lights, malfunctioning power windows, or a security system that has a mind of its own—the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable problems. Don’t let a faulty module keep you from enjoying your vehicle. This direct-fit replacement BCM, programmed specifically for your truck, is the definitive solution to restore order and functionality.
Expert Pro Tip
Before condemning your BCM, always verify your vehicle’s battery health and check for solid ground connections. A weak battery or a corroded ground wire (especially the one on the frame under the driver’s door) can cause low-voltage situations that mimic the symptoms of a bad BCM. A quick check with a multimeter can save you time and ensure you’re targeting the right problem.
Common Symptoms of a Failing BCM
- âś” Power windows, door locks, or mirrors working intermittently or not at all.
- âś” Interior dome lights or exterior parking lights staying on and draining the battery.
- âś” The factory security system engaging randomly or preventing the engine from starting.
- âś” Keyless entry remote failing to lock or unlock the doors.
- âś” Instrument cluster gauges or warning lights behaving erratically.
- âś” Radio or climate control systems not functioning correctly.
- âś” Communication errors with diagnostic scan tools.
The Simple, Dealer-Free Solution: A Pre-Programmed 2000 Yukon BCM
Typically, replacing a BCM involves a trip to the dealership for expensive and time-consuming programming. We eliminate that hassle completely. When you order from us, you provide your vehicle’s 17-digit Vehicle Identification Number (VIN), and our technicians will program the module with the latest GM software updates specific to your truck’s factory options. This ensures that when the BCM arrives, it’s ready for installation, saving you hundreds of dollars in dealer fees and getting you back on the road faster.
This module is a direct replacement for part numbers 9377486, 16257155, 15136876, and 09377486. It is designed to fit the following 2000 model year vehicles:
- Chevrolet Suburban 1500 & 2500
- Chevrolet Tahoe
- GMC Yukon (excluding Denali)
- GMC Yukon XL 1500 & 2500
Installation and Post-Install Procedures
The BCM is located under the dashboard on the driver’s side. Installation is straightforward: disconnect the negative battery terminal, unplug the electrical connectors from the old module, remove it, and install the new one in its place. Once the new module is installed and the battery is reconnected, most functions will be immediately restored.
In some cases, two additional procedures may be required to sync the new BCM with other vehicle systems. These typically require a bi-directional scan tool, which most professional repair shops have.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is a simple command performed with a professional diagnostic tool.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation. This is also a quick procedure performed via a scan tool.
With our pre-programmed 2000 Yukon BCM, you get a reliable, cost-effective repair that restores your vehicle’s electronic functions to factory specifications. Plus, with no core charge, you can keep your original module without the hassle of shipping it back.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready to be installed, flashed with the latest GM software for your specific vehicle.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific truck. It contains information about the manufacturer, model year, and factory-installed options. We use the VIN to load the exact software and calibration files your vehicle requires for all features to work correctly.
Where is the BCM located on my 2000 Yukon/Tahoe/Suburban?
The Body Control Module is typically located on the driver’s side, up under the dashboard, often near the steering column or emergency brake pedal assembly.
What happens if the airbag light is on after I install the new BCM?
This is a common occurrence and simply means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a plug-and-play part?
For most functions, yes. Because we pre-program it, your power windows, locks, lights, and other core features should work immediately after installation. However, as noted, a final sync procedure for the airbag system or brake sensor may be required depending on your vehicle.
My original part number is 16257155. Will this part work?
Yes. This BCM, part number 9377486, is a direct, compatible replacement for several part numbers, including 16257155, 15136876, and 09377486. We will program it to function identically to your original module.
