Are you experiencing frustrating electrical issues in your 2001 GM truck or SUV? Flickering dashboard lights, malfunctioning power windows and locks, or a security system that acts up on its own are common 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 and intermittent problems. This replacement Body Control Module, part number 09370249, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We make the repair process simple. Unlike going to a dealership, 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 flash the module with the latest official GM software updates before it ships. This ensures a seamless plug-and-play installation, eliminating the need for expensive dealer programming.
From the Diagnostic Bay
We had a 2001 Silverado 2500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would stay on, and the power locks worked only when they felt like it. The owner had already replaced the battery and checked all the fuses. After hours of chasing wires, we hooked up our scanner and saw communication errors pointing directly to the BCM. A failing BCM can send faulty signals throughout the vehicle, mimicking a dozen other problems. Swapping in a pre-programmed BCM like this one solved every single issue in under 30 minutes. It’s often the hidden culprit behind the most baffling electrical gremlins.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all
- ✔ The security system or alarm malfunctioning or preventing the vehicle from starting
- ✔ Horn honking unexpectedly
- ✔ Inaccurate or dead gauges on the instrument cluster
- ✔ “Service Vehicle Soon” or other warning lights illuminated on the dash

Installation and Post-Install Procedures
The BCM is typically located on the driver’s side, under the dashboard. Installation is a straightforward unbolt-and-unplug process. However, after installing the new module, some vehicles may require additional steps:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control functionality.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN.
Is this BCM difficult to install?
The physical installation is relatively simple for someone with basic mechanical skills. It’s usually located under the driver’s side dashboard and involves removing a few panels and connectors. The main benefit of our product is that the difficult programming part is already done for you.
What if my airbag light is on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old, faulty BCM?
No. This product has no core charge. You can keep your original module without any extra fees or the need to return it.
