Is your GMC Savana or other GM truck experiencing bizarre electrical problems?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or strange warning lights on your dash, a failing Body Control Module (BCM) is the most likely cause. The BCM acts as the central nervous system for your vehicle’s body electronics. When it fails, it can create a cascade of frustrating and difficult-to-diagnose issues. This OEM-quality replacement BCM, part number 15198116, is the definitive solution for restoring your vehicle’s electronic systems to perfect working order.
We take the guesswork and expense out of the repair. Unlike a dealership, which requires costly programming appointments, we pre-program this module to your vehicle’s specific VIN before shipping. This ensures it arrives ready for a simple, plug-and-play installation, communicating seamlessly with your truck’s other modules right out of the box.

Expert Pro Tip
Before you begin the installation, always disconnect the negative terminal of your vehicle’s battery. This not only prevents accidental electrical shorts but also helps clear any lingering fault codes from the old, failing module. After installing the new BCM and reconnecting the battery, allow the vehicle to sit for a few minutes to initialize the new component.
Solving Your GM Truck’s Electrical Gremlins
A faulty BCM can manifest in numerous ways, often mimicking other component failures. By replacing it, you address the root cause of these problems. This module is the direct solution for a wide range of issues across many popular GM models, including the Chevrolet Silverado, Suburban, Tahoe, GMC Sierra, Yukon, and Cadillac Escalade.

Installation and Post-Install Considerations for your Savana 2500 Body Control Module
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column, or in the center dash on Savana and Express vans. It’s held in place by a few clips or bolts and has several wiring harnesses connected to it. The entire swap can often be completed in under 15 minutes.
In some cases, post-installation procedures may be necessary. If you see an airbag light after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function to sync the modules. Similarly, a ‘Brake Pedal Position Relearn’ might be required on certain models. There is no core charge for this part, so you can keep your old module without any hassle.
