Restore Full Functionality to Your GM Truck or SUV
Are you battling frustrating electrical problems in your 2001 GM truck or SUV? Issues like flickering lights, malfunctioning power windows and locks, or a security system that prevents your vehicle from starting are often traced back to a failing Body Control Module (BCM). This module is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement BCM, part number 09375899, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
The greatest advantage of this unit is our complimentary VIN programming service. Before we ship your part, our technicians will flash the module with the latest GM software updates, specifically matched to your vehicle’s Vehicle Identification Number (VIN). This critical step ensures compatibility and saves you from a costly and time-consuming trip to the dealership for programming. You receive a part that is ready for installation right out of the box.
Common Symptoms of a Failing 2001 Silverado Body Control Module
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security or anti-theft system light is illuminated, possibly causing a no-start condition.
- ✔ The horn honking randomly or the panic alarm activating without reason.
- ✔ Inconsistent or non-functional dashboard gauges and warning lights.
- ✔ Communication errors when scanning the vehicle with a diagnostic tool.
From the Diagnostic Bay
We had a 2001 Sierra 2500 in the shop that was a true head-scratcher. The owner had replaced the battery, alternator, and multiple window switches trying to solve a collection of bizarre electrical issues. The dome light would stay on, the driver’s window worked only when it wanted to, and the horn would chirp randomly. After confirming all the basic wiring was sound, we hooked up our professional scanner and saw multiple communication loss codes with the BCM. We installed a VIN-programmed BCM, and instantly, every single issue was resolved. It’s a powerful reminder that the BCM is the brain of the body, and when it’s not healthy, the whole system suffers.
Installation and Post-Install Procedures
This BCM is located on the left-hand (driver’s) side of the dashboard. While the physical replacement is straightforward for a DIYer with basic tools, please be aware of potential post-installation steps. Because this module interacts with other critical systems, your vehicle may require one or more of the following relearn procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and traction control function, a brake pedal position sensor recalibration may be needed.
Disclaimer: Specific requirements can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive and program it with your VIN.
Is this part really plug-and-play?
It is pre-programmed to your VIN, which handles the most complex part of the installation. However, as noted, some vehicles may require additional ‘relearn’ procedures for systems like the airbags or brakes, which need a compatible scan tool.
My original part number is 9392990. Will this work?
Yes. This BCM is a direct, compatible replacement for all part numbers listed, including 09375899, 9392990, 09370249, and 19180223.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
What happens if the airbag light comes on after I install it?
This indicates the BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be synced. A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
