Restore Your Truck’s Electrical System and Drive with Confidence
Are strange electrical problems plaguing your 2001 GM truck or SUV? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or random warning lights can all point to a failing Body Control Module (BCM). This vital component is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable issues. Get back in control with this fully programmed, ready-to-install BCM.
Common Symptoms & Your Solution
A faulty BCM can be difficult to diagnose because its symptoms often seem unrelated. If your truck is experiencing any of the following, our pre-programmed 2001 GM Truck BCM 9375899 is the reliable, cost-effective solution you need:
- Power windows, door locks, or mirrors working intermittently or not at all
- Interior dome lights or dashboard lights staying on or not turning on
- Erratic behavior from the radio or climate controls
- The security or anti-theft system preventing the vehicle from starting
- False warnings on the instrument cluster (e.g., “Service 4WD” light)
- Communication error codes (U-codes) when scanned with a diagnostic tool
Instead of paying for expensive dealership diagnostics and programming, this module arrives flashed with the latest GM software specifically for your vehicle’s VIN. It’s the most direct path to restoring your truck’s proper function and your peace of mind.

Expert Insight: The Pre-Programmed Advantage
From over 20 years of hands-on diagnostics, I can tell you that the biggest hurdle in replacing a modern module like a BCM is the programming. In the past, this was a dealer-only job. You’d install the part, and the truck would still be dead in the water until it was towed to a dealer for a costly programming session. Our VIN-programming service completely eliminates that step. We handle the complex part, so you can perform the installation with confidence. This 2001 GM Truck BCM 9375899 turns a major repair into a manageable weekend project for a skilled DIYer or a quick, profitable job for an independent shop.
Installation & Post-Install Procedures
After providing us with your VIN during checkout, we will program the module and ship it to you. Installation involves locating the original BCM (typically under the driver’s side of the dashboard), disconnecting the battery, swapping the modules, and reconnecting everything. While the module is programmed for your main vehicle functions, some security and safety systems may require a relearn or sync procedure with a professional scan tool after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required for proper brake light and traction control operation.
We provide the most critical component—a properly programmed 2001 GM Truck BCM 9375899—to get your vehicle back on the road quickly and reliably.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, interior and exterior lighting, the security system, and even the wipers.
Do I absolutely need to provide my VIN?
Yes. Providing your Vehicle Identification Number (VIN) is mandatory. We cannot ship the module without it. The VIN is essential for us to load the correct software and vehicle-specific options, ensuring the BCM works correctly right out of the box.
Is this BCM difficult to install?
For someone with moderate mechanical experience, the physical installation is straightforward. It is typically located under the driver’s side dashboard and involves unplugging connectors and removing a few bolts. The most important part, the programming, is already done for you.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bi-directional diagnostic scan tool, such as a GM Tech 2 or equivalent professional-grade scanner. Basic code readers cannot perform these functions.
Will this fix my specific electrical problem?
This module is the definitive solution for failures within the BCM itself. If your vehicle is exhibiting multiple symptoms from the list above, it is highly likely that the BCM is the root cause. However, we always recommend proper diagnostics to rule out wiring or sensor issues.
What happens if the airbag light comes on after I install it?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag control module (SDM). A qualified mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to sync the systems and turn off the light.
