Restore Full Functionality to Your GM Truck or SUV
Are you battling strange and frustrating electrical issues in your 2001 GMC Yukon or similar GM truck? Flickering lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of problems that are difficult to diagnose. This isn’t just an inconvenience; it can affect your vehicle’s security and safety systems. This replacement BCM, part number 9392990, is the reliable, straightforward solution to get your truck’s features working correctly again.
We take the guesswork and high dealership costs out of the equation. This isn’t just a part in a box; it’s a comprehensive cloning service. When you order, you’ll provide your vehicle’s VIN. Our technicians will then program this module with the latest GM software specific to your truck. This means when it arrives at your door, it’s ready for installation, saving you from needing specialized, expensive scan tools or a trip to the dealer for programming. It’s the most efficient way to solve your BCM-related headaches.
Case Study: A Tricky Diagnosis
I remember a 2001 Silverado 1500 that came into my bay with a bizarre complaint: the radio would turn on by itself, and the power door locks would cycle randomly, sometimes even while driving. The owner had already replaced the battery and checked all the fuses. Diagnostics showed no clear trouble codes pointing to a single component. From experience, I know these ghost-like issues on GMT800 platforms often lead back to the BCM. We swapped in a programmed BCM, and the gremlins vanished instantly. It’s often not one big failure, but dozens of small internal connection issues within the original module that cause this chaos.
Common Signs of a Failing GM BCM
- ✔ Power windows or door locks operate erratically or not at all.
- ✔ The security or anti-theft light stays on, potentially causing a no-start condition.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The horn honks unexpectedly.
- ✔ Dashboard gauges behave erratically or stop working.
- ✔ The radio or HVAC controls malfunction.
- ✔ Communication-related DTCs like U-codes (e.g., U0140, U0100) may be present.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to discharge.
- ✔ Locate the BCM: On most of these GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, to the left of the steering column.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove the fasteners holding the module in place and take it out.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely fasten it. Reconnect all the electrical connectors, ensuring they click into place.
- ✔ Reconnect Battery: Reattach the negative battery terminal. The vehicle is now ready for the final steps.
Important Post-Installation Steps
After installing your new 2001 Yukon BCM, a couple of system relearn procedures may be necessary to ensure everything communicates correctly. These are often required when key security and safety components are changed.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Why do you need my VIN?
Your VIN is essential for our cloning service. It allows us to access the exact GM factory calibration file for your vehicle’s specific options and features. We program the BCM with this data and the latest software updates, ensuring it works seamlessly with your truck right out of the box.
Is this a simple plug-and-play installation?
For the most part, yes. Because we pre-program the module, you avoid the most difficult step. You simply swap the hardware. However, as noted, some vehicles may require a ‘relearn’ procedure for the airbag or brake systems, which requires a capable scan tool.
What is your core policy?
We believe you should keep what’s yours. We do not require a core deposit, and we always return your original module with the programmed replacement unit we ship to you. We do not keep your old part.
Will this fix my ‘Service 4WD’ light?
While a BCM can cause a wide range of issues, a ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM), the encoder motor, or the dash switch. This 2001 Yukon BCM primarily controls body functions like lights, windows, and security.
How do I find my original BCM part number?
The part number is printed on a sticker directly on the case of your BCM. You will need to access the module (typically under the driver’s side dash) to read it. Verifying the part number ensures a perfect match.
