Is your 2001 GM truck or SUV experiencing bizarre electrical problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange warning messages on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central computer responsible for managing your vehicle’s body electronics. When it starts to fail, it can cause a wide range of frustrating and unpredictable issues that can be difficult to diagnose.
From the Diagnostic Bay
We had a customer with a 2001 Silverado whose power door locks would randomly cycle while driving down the road. He’d already replaced two lock actuators with no success. After a quick scan, we saw communication fault codes pointing to the BCM. Replacing the module with a properly programmed unit solved the phantom lock issue and also fixed a dim dome light he hadn’t even mentioned. These modules control so many functions, a single failure can create a cascade of seemingly unrelated problems.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Vehicle security system engaging randomly or preventing the engine from starting.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Wipers operating intermittently or at the wrong speed.

Don’t waste time and money at a dealership. This replacement Body Control Module is the perfect solution to restore your vehicle’s functionality. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific VIN before we ship it. This ensures compatibility with your exact options and features, making installation as straightforward as possible. Simply provide your VIN after purchase, and we’ll handle the complex programming for you.
This module is a direct replacement for part numbers: 09375899, 9392990, 09370249, and 19180223. There is no core charge, so you can keep your original part.
Post-Installation Information
After installing your new BCM, a couple of simple relearn procedures may be necessary depending on your vehicle’s configuration. These are standard steps when replacing this type of module.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform a “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function correctly.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors many of the electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How does the VIN programming process work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the latest GM software and your vehicle’s specific configuration onto the BCM before it ships. This makes the installation process much simpler for you.
Is this part difficult to install?
The physical installation is typically straightforward. The BCM is located under the driver’s side of the dashboard. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, as noted, some post-installation electronic procedures may be required with a professional scan tool.
Will I need a mechanic to perform any procedures after I install it?
Possibly. If the airbag light comes on, or if you notice issues with brake light operation, you will need a mechanic with a professional-grade diagnostic tool to perform the Airbag System Sync and/or Brake Pedal Position Relearn procedures.
Do I need to send my old BCM back?
No. This part is sold with no core charge, so you are not required to return your original module.
How do I know this fits my truck?
This module fits a wide range of 2001 GM models including the Suburban, Tahoe, Yukon, Silverado, and Sierra. It is a direct replacement for part numbers 09375899, 9392990, 09370249, and 19180223. The best way to ensure compatibility is to match one of these part numbers from your original BCM.
