Restore Your Truck’s Electrical System and Drive with Confidence
Are you battling frustrating and unpredictable electrical problems in your GM truck or SUV? Flickering lights, malfunctioning power locks, a security system that acts on its own, or warning lights that won’t turn off are common signs of a failing Body Control Module (BCM). This vital component is the central hub for your vehicle’s body electronics, and when it starts to fail, it can make your trusted vehicle feel unreliable. Get back to normal with this direct-fit, professionally programmed BCM, designed to restore your vehicle’s factory functions and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of issues that seem unrelated. If you’re experiencing any of the following, this module is your definitive solution:
- Intermittent or non-working power windows, door locks, or mirrors.
- Erratic interior or exterior lighting behavior.
- The security or anti-theft system preventing the vehicle from starting.
- False warnings on the instrument cluster (e.g., “Service 4WD”).
- Poor battery life due to parasitic draw from a faulty module.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine OEM module and flash it with the latest GM software updates specifically for your vehicle using the VIN you provide.

An Expert’s Insight on GMT800 Electricals
As a technician with over two decades of experience, I’ve seen countless early 2000s GM trucks like the Silverado and Suburban with these exact BCM issues. The original modules were susceptible to failure from voltage spikes and internal component degradation over time. The result is what mechanics call “electrical gremlins.” The most important part of the fix isn’t just swapping the box—it’s the programming. The BCM needs to know your vehicle’s specific options (RPOs), like whether you have power seats or keyless entry. Our VIN-based programming for the 2002 Suburban 1500 BCM 15095334 ensures it works correctly right out of the box, saving you from the headache and expense of a dealership visit for calibration.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power locks, the alarm system, interior and exterior lighting, and instrument panel warnings. When it fails, these systems can behave erratically.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your specific vehicle’s features and options. This makes the installation plug-and-play and ensures everything works as it did from the factory.
Is this part difficult to install?
Physically, the BCM is typically located under the steering column or center dash and is held in by a few bolts or clips. For most DIYers with basic tools, the replacement is straightforward. Since we handle the programming, you avoid the most complex part of the job.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag system (SDM). This is done with a procedure called “Setup SDM Primary Key in BCM” using a professional scan tool. This is only necessary if the airbag warning light appears after you install the new module.
Do I need to send my old part back?
No, there is no core charge for this item. You can keep your original module.
Will this fix my “Service 4WD” light?
A faulty BCM is a very common cause for a false “Service 4WD” message on these GM models. While other issues can cause this light, replacing a known-bad BCM like the 2002 Suburban 1500 BCM 15095334 often resolves this specific problem.
