Are you battling frustrating electrical gremlins in your 2001 GM truck or SUV? Inconsistent power windows, flickering lights, or strange warning messages are often signs 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 confusing issues. This replacement BCM, part number 09392990, is the definitive solution to restore your vehicle’s functionality and reliability.
We take the guesswork and hassle out of the repair process. Unlike a generic part from a local store, this BCM comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our technicians will load the latest GM software onto the module. This means no expensive trips to the dealership for programming—it’s ready for installation right out of the box, saving you time and money.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system preventing the vehicle from starting (Security light on).
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ The radio or climate control system behaving unpredictably.
- ✔ False warning messages like “Service Vehicle Soon” appearing on the dash.
Installation and Setup for Your 2001 Silverado BCM
Physical installation is straightforward. The BCM is typically located under the driver’s side of the dashboard. Once the new module is connected, your vehicle should start and most functions will be restored immediately. However, depending on your vehicle’s specific configuration, a couple of additional steps might be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
This is a direct replacement for part number 09392990 and is also interchangeable with part numbers 09375899, 9392990, 09370249, and 19180223. Best of all, there is no core charge, so you can keep your original module.

Frequently Asked Questions
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories. This includes power windows, locks, interior and exterior lighting, security systems, wipers, and more. It acts as a central hub for these functions.
Do I need to get this part programmed?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN during or after checkout, and it will arrive ready to install with the latest software from GM.
Where is the BCM located on my truck?
On most 2001 GM trucks and SUVs like the Silverado and Sierra, the BCM is located on the driver’s side, up under the dashboard to the left of the steering column.
What happens if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a guaranteed fix for my electrical problems?
This BCM will fix any problem directly caused by a faulty module. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis to rule out other issues like bad wiring or faulty switches.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
