Restore Full Electronic Functionality to Your GM Truck or SUV
Are you battling strange and frustrating electrical problems in your 2000 GM truck or SUV? Issues like flickering lights, malfunctioning power windows and locks, or a persistent security warning are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement BCM, part number 09377486, is the definitive solution to restore your vehicle’s proper operation and reliability.
We had a 2000 Yukon come in with a classic case of BCM failure. The owner was frustrated with intermittent dome lights that wouldn’t turn off, a radio that would randomly shut down, and the dreaded ‘Service Security System’ message on the dash. After confirming power and grounds were good, we diagnosed the BCM. Instead of a costly trip to the dealership for a new module and programming, we installed one of our pre-programmed units. The installation was straightforward, and upon startup, all the ghost-like electrical issues were gone. The customer was thrilled to have their truck back to normal without the dealership hassle.
Common Symptoms of a Failing 2000 Suburban BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or the ‘Service Security System’ light staying on.
- ✔ The radio or climate controls behaving unpredictably.
- ✔ Communication issues between various electronic modules, leading to multiple warning lights.
- ✔ Inconsistent or non-working remote keyless entry (RKE).
Plug-and-Play Solution Programmed to Your VIN
Getting your vehicle back on the road shouldn’t be complicated. That’s why we offer this BCM fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN during checkout, and our technicians will flash the module with the latest GM software updates for your exact configuration. This means no expensive programming tools or trips to the dealership are required. It arrives at your door ready for installation.
Post-Installation Procedures
While this module is designed for a straightforward swap, some 2000 GM models may require additional steps after installation to ensure all systems communicate correctly. These are not always necessary but are important to be aware of:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be needed. This syncs the new BCM with the airbag system and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN allows us to program the BCM with the specific software and settings for your truck’s options, such as power seats, keyless entry, and security system. This ensures it works correctly right out of the box.
Is this BCM difficult to install?
The BCM is typically located under the driver’s side of the dashboard. Installation involves disconnecting the battery, removing a few trim panels, and swapping the module. It is a manageable job for a DIYer with basic tools.
Do I need to send my old BCM back?
No. This purchase has no core charge, so you can keep your original module.
What if my airbag light comes on after I install it?
This can happen occasionally. It 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 to resolve this.
Will this fix my power windows and locks?
If the BCM is the cause of your power window and lock failure, then yes, this part will correct the issue. The BCM is the most common point of failure for these types of widespread electrical problems.
