Is your 2001 GM truck experiencing bizarre electrical problems? Flickering lights, malfunctioning power windows, 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 computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating issues. This replacement Body Control Module is the definitive solution, arriving at your door pre-programmed to your truck’s specific VIN with the latest GM software updates.
Common Symptoms of a Failing BCM
If you’re noticing any of the following issues, a faulty BCM is the likely culprit. Replacing it can restore proper function and reliability to your vehicle.
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Security system or keyless entry malfunctions.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Unexplained battery drain when the vehicle is off.

Installation and Post-Install Notes:
Installation is typically plug-and-play. The BCM is located on the driver’s side, under the dashboard. However, depending on your vehicle’s specific configuration, a couple of simple relearn procedures may be necessary after installation.
- Airbag System Sync: If your 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: In some cases, a brake pedal position sensor recalibration may be required to ensure your brake lights and traction control system function correctly.
- No Core Charge: You are not required to send your old module back. Keep your original part with no extra fees.

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 like power windows, lights, door locks, the security system, and wipers. It acts as the central hub for your truck’s body electronics.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship it.
Is this BCM difficult to install?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is usually located under the driver’s side of the dashboard. The main benefit of our product is that the complex programming is already done, making it a plug-and-play process.
Will this fix my airbag light?
If the airbag light comes on after installing the new BCM, it’s because the new module needs to be electronically ‘introduced’ to the airbag system. This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. The BCM itself does not fix an existing airbag fault.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep your original module without any additional fees or hassle.
