Is your 2000 GMC Yukon, Tahoe, or Suburban suffering from bizarre electrical issues?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central computer for your truck’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement BCM, part number 9377486, is the definitive solution to restore your vehicle’s electronic functions to factory-perfect condition.
From the Diagnostic Bay
We had a 2000 Chevy Tahoe come in that was driving the owner crazy. The interior dome lights would stay on intermittently, draining the battery overnight. He’d already replaced the battery twice. After checking door jamb switches and wiring, we hooked up our scanner and found communication faults pointing directly to the BCM. We installed a VIN-programmed BCM just like this one, and the problem was solved instantly. It’s a classic failure mode for these trucks, and a new module is the only reliable fix.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Inconsistent or dead dashboard gauges and warning lights.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Problems with the radio or climate control systems.

Post-Installation Procedures
While this module is programmed for your vehicle, some systems may require a final synchronization step after installation. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after you install the BCM, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and dashboard gauges.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as programming is a required step.
Is this BCM difficult to install?
The BCM is typically located under the driver’s side of the dashboard. It is held in by a few bolts or clips and has several electrical connectors. For someone with basic mechanical skills, it is a manageable job. However, if you are not comfortable working around vehicle wiring, we recommend professional installation.
What if my airbag light comes on after installation?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional 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 purchase has no core charge. You can keep your original module.
