Is Your 2001 GM Truck Experiencing Bizarre Electrical Issues?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange behavior from your gauges, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and hard-to-diagnose problems. Don’t let electrical gremlins keep your truck off the road. This direct-fit replacement BCM is the solution you need.
From the Diagnostic Bay
We had a 2001 Silverado 2500 in the shop that was driving the owner crazy. The dome light would stay on, the driver’s side power window worked only when it wanted to, and the radio would randomly shut off. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. We installed a VIN-programmed BCM, and instantly, all the strange electrical issues were gone. It’s a perfect example of how one single component, the 2001 Sierra BCM, can be the root cause of multiple, seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system or anti-theft light flashing, preventing the vehicle from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Intermittent issues with the radio or climate control system.
- ✔ False warnings on the driver information center.

When you purchase this module, you simply provide us with your vehicle’s 17-digit VIN. Our technicians will then program the BCM with the latest software updates from GM, ensuring it is perfectly matched to your truck’s specific options and configuration.

This module is a direct replacement for part numbers: 09375899, 9392990, 09370249, and 19180223.
Installation and Post-Install Procedures
Physically installing the BCM is typically a simple process, as it’s a plug-and-play module located under the driver’s side dash. However, after installation, some vehicles may require additional electronic relearn procedures. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Core Policy: There is no core charge for this part. You can keep your old module.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of its electronic accessories, such as power windows, locks, interior/exterior lighting, security system, wipers, and more.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What if my airbag light comes on after I install the BCM?
This can happen occasionally. It means the new BCM needs to be electronically synced with the airbag system’s computer (SDM). A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
My original part number is 09375899. Will this part work?
Yes. This BCM, part number 09392990, is a direct replacement for several part numbers, including 09375899, 09370249, and 19180223. As long as your vehicle is listed in the fitment guide, this part will work correctly.
