Is Your 2000 GM Truck or SUV Experiencing Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows, or a security system that has a mind of its own, the culprit is likely a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, coordinating everything from the interior lights and door locks to the instrument cluster and security system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues, making your reliable truck feel unpredictable.
Expert Pro Tip
Before replacing your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (especially the main ground from the battery to the chassis and engine block). A weak battery or a corroded ground can cause voltage drops that mimic the symptoms of a failing BCM. A few minutes with a multimeter can save you from replacing a perfectly good module.
Symptoms of a Failing 2000 Yukon BCM
A faulty Body Control Module can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your BCM needs attention:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not turning on, or flickering erratically.
- ✔ The security system engaging randomly or the “Security” light staying illuminated on the dash.
- ✔ Inaccurate or dead gauges on the instrument panel.
- ✔ Radio or climate control systems behaving strangely.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
- ✔ The vehicle failing to start despite having a good battery and starter.

Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software updates specific to your truck. This ensures a seamless installation process, getting you back on the road quickly and confidently.
This module is a reliable replacement for several part numbers, including 16257155, 15136876, 09377486, and 9377486. By purchasing this pre-programmed 2000 Yukon BCM, you are getting a part that is ready for installation right out of the box, saving you a costly trip to the dealership and hours of diagnostic headaches.
Installation and Post-Install Procedures
The BCM is typically located on the driver’s side, under the dashboard. While the physical replacement is straightforward, a couple of post-installation procedures, known as ‘relearns’, may be necessary depending on your specific vehicle’s configuration.
- Airbag System Sync: If the airbag warning light is on after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function correctly.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about performing these procedures.
Frequently Asked Questions
What does a BCM do on my 2000 Yukon?
The Body Control Module (BCM) acts as the central computer for your truck’s electronic accessories. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, the security system, and the instrument cluster gauges.
Is this BCM ready to install or does it need programming?
This BCM comes fully programmed to your vehicle’s specific VIN. You must provide us with your VIN at the time of purchase. This service ensures the module is ready for installation upon arrival, saving you a trip to the dealership.
What is a core charge and do I have to pay one?
A core charge is a deposit you pay until you return your old part. However, this product has no core charge! You can keep your original module without any extra fees or the hassle of returning it.
Why is my airbag light on after installing the new BCM?
The airbag light may illuminate because the new BCM needs to be electronically synced with the vehicle’s existing airbag computer (SDM). This requires a specific ‘Setup SDM Primary Key in BCM’ procedure, which must be performed using a professional diagnostic tool.
Where is the BCM located on my 2000 Tahoe or Suburban?
On these models, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column. It’s a black plastic box with several large wiring harnesses connected to it.
