Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
If your 2001 GMC Yukon, Tahoe, Silverado, or Sierra is acting possessed—with flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues. This replacement BCM, part number 09392990, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2001 Sierra 2500 come into the shop with a list of complaints the owner called ‘ghosts in the machine.’ The dome lights would stay on, the radio would shut off randomly, and the power door locks only worked intermittently. After checking fuses and grounds, all diagnostics pointed to an internal failure in the BCM. Instead of a complicated and expensive wiring chase, we installed a VIN-programmed BCM. The moment it was connected, all the phantom issues vanished. It’s a common story for these trucks, and a new BCM is almost always the fix.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft light staying illuminated on the dash.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Wipers activating on their own or not responding to the switch.

Post-Installation Procedures
While this module is designed for straightforward installation, some vehicles may require simple relearn procedures after the BCM is connected. These are standard for this type of repair:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system operate correctly.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this BCM difficult to install?
Installation is straightforward. The BCM is typically located under the driver’s side of the dashboard. You simply disconnect the battery, unplug the old module, plug in the new one, and reconnect the battery. However, as noted, some minor electronic relearn procedures may be required afterward.
How do I provide my VIN for programming?
You can add your 17-digit VIN to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it before we ship your order.
What happens if my airbag light is on after I install this?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep your original BCM.
