Restore Your GM Truck’s Electrical System
Are you experiencing frustrating and unpredictable electrical problems in your 2001 GM truck or SUV? Issues like malfunctioning power windows, erratic interior lights, a faulty security system, or other strange electrical behavior are common indicators 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 problems. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by pre-programming this module to your vehicle’s unique Vehicle Identification Number (VIN). This ensures it has the latest software updates from GM and communicates perfectly with your truck’s other systems right out of the box. Simply provide your VIN after purchase, and we’ll handle the complex programming for you.
From the Diagnostic Bay
We recently worked on a 2001 Chevy Tahoe that had its owner completely stumped. The power locks would cycle randomly while driving, and the radio would shut off intermittently. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes pointing directly to the BCM. We installed one of these VIN-programmed modules, and the problems vanished instantly. It’s a classic case where a single faulty component creates a cascade of confusing symptoms.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights or dashboard lights flickering, staying on, or failing to illuminate.
- ✔ “Service Theft System” or “Security” light illuminated on the dash.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Radio or climate control system malfunctions.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss (U-codes).

Installation and Post-Install Information
Installation is a straightforward process of locating the old BCM (typically under the driver’s side dashboard) and swapping it with this new, pre-programmed unit. Because it’s already flashed to your VIN, you avoid a costly trip to the dealership for programming. However, in some cases, minor post-installation procedures may be required:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Please note: No core charge is required. You can keep your old part.
Frequently Asked Questions
How does the VIN programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will then use this number to flash the BCM with the specific software and latest updates for your exact vehicle configuration before we ship it.
Is this part truly plug-and-play?
For most vehicle functions, yes. The VIN programming handles the majority of the setup. However, due to the complexity of modern vehicle systems, some models may require a simple relearn procedure for the airbag or brake systems, as detailed above. This can be performed by a qualified mechanic or with a high-level diagnostic tool.
How can I be sure my BCM is the problem?
The symptoms listed on this page are strong indicators of BCM failure. The most accurate way to confirm is to have a professional technician perform a diagnostic scan. They can check for communication codes (U-codes) and directly test the BCM’s functionality.
My original part number isn’t 9392990, will this still work?
Yes, if your original part number is 09375899, 9392990, 09370249, or 19180223, this module is the correct replacement and will function identically.
Do I have to send my old BCM back?
No. There is no core charge associated with this part, so you are not required to return your original module.
