Restore Full Electronic Control to Your 2000 GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2000 GMC Yukon, Chevy Tahoe, or Suburban? Issues like flickering lights, malfunctioning power windows and locks, a dead battery overnight, or a persistent security light are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it falters, it can cause a cascade of unpredictable and annoying problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s factory functions and reliability.
From the Diagnostic Bay
We had a 2000 Yukon XL 2500 in the shop that was on its third new battery in six months. The owner was convinced he had a bad alternator or a short somewhere, but everything checked out. After hours of tracing wires, we hooked up a scope to the battery with everything off. We found a significant parasitic draw that would appear intermittently. The culprit? The original BCM wasn’t letting all the vehicle’s systems go to ‘sleep’ after shutdown, slowly draining the battery every night. Installing a new, properly functioning BCM solved the problem instantly, saving the owner from buying a fourth battery and endless diagnostic headaches.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior dome lights or exterior headlamps and taillights.
- ✔ The security system light stays on, or the vehicle won’t start due to a false security alert.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ Unexplained battery drain that kills your battery overnight or after a few days.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Diagnostic trouble codes related to communication loss with other modules (U-codes).

Simple, VIN-Programmed Installation Process
Forget expensive trips to the dealership for programming. This 2000 Yukon Body Control Module arrives at your door pre-programmed with the latest GM software updates, matched specifically to your vehicle’s VIN. The process is simple: place your order, provide us with your vehicle’s VIN, and we handle the rest. This ensures that the module is ready for installation right out of the box, saving you time, money, and hassle. While the unit is designed for a straightforward installation, some vehicles may require a post-installation procedure as detailed below.
Post-Installation Requirements
After installing your new BCM, one or two additional steps may be necessary to ensure all systems communicate correctly. These are standard procedures for this type of repair.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and traction control functionality.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function.
Is this part truly plug-and-play?
For most vehicles, yes. Because we program it to your VIN, it should function immediately upon installation. However, as noted, some vehicles may require an airbag sync or brake pedal relearn procedure with a professional scan tool to clear warning lights.
What if my airbag light is on after I install the BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A repair shop with a high-level diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to return my old BCM?
No. This part is sold with no core charge. You can keep your original module.
Will this fix my vehicle’s no-start problem?
If your no-start issue is caused by the factory anti-theft system (Passlock) being triggered by a faulty BCM, then yes, this part will resolve it. The security light being on or flashing is a strong indicator of this type of failure.
