Restore Your Truck’s Electrical System and Drive with Confidence
Are you battling bizarre and frustrating electrical problems in your GM truck or SUV? Flickering lights, intermittent power windows, a security light that won’t turn off, or gauges that have a mind of their own are all classic signs of a failing Body Control Module (BCM). Don’t let these electrical gremlins keep your reliable vehicle off the road. This pre-programmed BCM is the definitive, hassle-free solution to restore your truck’s full functionality and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, it’s highly likely your BCM is the culprit:

Expert Insight: Why a Programmed Module is a Smarter Fix
As a technician, I’ve seen countless owners of great trucks like the Silverado, Suburban, and Tahoe get frustrated by BCM failures. These modules are the central hub for all body electronics, and after years of heat cycles and constant use, internal components and solder joints can fail. Grabbing a used module from a salvage yard might seem like a cheap fix, but it’s a gamble. It won’t be programmed for your vehicle’s specific options, leading to new problems and an inevitable trip to the dealer. Our solution provides a reliable part, loaded with the latest stable software from GM and programmed to your exact VIN. It’s the right way to fix the problem once and for all.
Important Post-Installation Information
While this module is designed for a simple installation, some vehicles may require one or more relearn procedures to sync with the new BCM. These are standard procedures for this type of repair.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary on some models to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine-related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, climate controls, and more.
How do I know if my BCM is failing?
Common signs include erratic behavior of your electronic accessories, such as lights flickering, windows not working, the security light staying on, or gauges acting strangely. A single one of these issues could be a bad switch or wire, but multiple, seemingly unrelated electrical problems often point directly to the BCM.
Is this really a plug-and-play installation?
Yes, because we program it to your VIN, it is designed to be plug-and-play. It eliminates the need for dealership programming. However, as noted above, some vehicles may require a simple relearn procedure for the airbag or brake systems, which can be done with a compatible professional scan tool.
Where is the BCM located on my 2002 Tahoe?
On the 2002 Tahoe and similar GM trucks/SUVs, the BCM is typically located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it is usually found behind the center dash area.
What happens if I don’t provide my VIN?
Providing your VIN is essential. We cannot ship your order without it, as the programming process is what makes this module work correctly with your specific vehicle’s features and security system. After your purchase, we will contact you for the VIN.
What does the one-year replacement warranty cover?
The one-year replacement warranty covers any defects in the module itself. If the unit fails within one year of the purchase date, we will provide a replacement part. This gives you confidence in the quality and reliability of your repair.
