Is Your Truck or SUV Acting Possessed?
Are you dealing with a frustrating mystery of flickering lights, malfunctioning power windows, a security system that randomly goes off, or gauges that have a mind of their own? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). In your GM truck or SUV, the BCM is the central command for most of the electronic accessories you use every day. When it starts to fail, it can make your dependable vehicle feel unreliable and chaotic. It’s time to stop chasing electrical gremlins and install a permanent, reliable solution.
Common Symptoms & Your Solution
If you’re experiencing any of the issues below, a failing BCM is the most likely culprit. This pre-programmed module is the definitive fix, designed to restore your vehicle’s electrical system to perfect factory operation. Stop guessing and get the right part, ready to install right out of the box.

Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless DIY repairs get stalled by programming. A BCM isn’t like a simple sensor; it’s tailored to your vehicle’s exact options—from the type of transmission to whether you have power seats. Ordering a generic, non-programmed module from a junkyard or parts store is a recipe for disaster. It simply won’t work. Our process of programming the BCM to your specific VIN before we ship is the secret to a successful, hassle-free repair. We handle the complex part so you can enjoy a simple installation.
Important Post-Installation Steps
While this module is designed for a straightforward installation, some vehicles may require one or more of the following procedures to ensure all systems communicate correctly. This is normal for this type of repair.
- Airbag System Sync: If the airbag warning light comes on after installation, the ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional diagnostic tool to sync the system and turn off the light. This is only required if the light is on.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on certain models to ensure proper brake light function and traction control system performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is the process after I order?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive it. Once we have your VIN, we will program the module with the latest GM software specific to your vehicle and ship it out to you, typically within 1-2 business days.
Do I really not need to get this programmed by a dealer?
That’s correct. The entire point of our service is to save you that time, money, and hassle. The programming is done by our expert technicians before the BCM ever leaves our facility. It will arrive at your door ready for a direct, plug-and-play installation.
What tools are needed for installation?
Installation is typically straightforward. You’ll need basic hand tools like a socket set and a screwdriver. The BCM is usually located under the driver’s side dashboard. We always recommend disconnecting the battery before starting any electrical work on your vehicle.
Will this fix my ‘Service 4WD’ light?
While a BCM can cause a wide variety of issues, a ‘Service 4WD’ message is more often related to the Transfer Case Control Module (TCCM), the encoder motor, or the switch in the dash. This BCM is not the typical solution for that specific problem.
What if my original part number is not on your list?
Please contact us with your vehicle’s VIN and the part number from your original BCM. The list provided covers the most common compatible numbers, but there may be others. We can verify compatibility for you to ensure you get the correct part.
