An Expert’s Diagnostic Tip: “Over my 20 years under the hood, I’ve seen countless BCMs get replaced when the real culprit was a bad ground. Before you install your new Programmed 25844480 BCM, take 10 extra minutes to check the main BCM ground connection—typically located on the driver-side A-pillar near the kick panel. A clean, tight ground ensures your new module can communicate perfectly and prevents the same frustrating issues from returning. It’s the single most important step for a successful, long-lasting repair.”
Frequently Asked Questions
Will this BCM be ready to install right out of the box?
Yes. We program the module to the VIN you provide during checkout. This ensures it communicates correctly with your vehicle’s other systems for a true plug-and-play installation, with no extra dealer visit required.
My airbag light is on. Will this fix it?
This module will often resolve the underlying electronic fault causing an airbag light, especially with code B1001. However, in some cases, a post-installation procedure called ‘Setup SDM Primary Key in BCM’ is needed. This can be done with a professional-grade scan tool and syncs the new BCM with the airbag system.
How difficult is the installation?
Installation is straightforward for a DIYer with basic tools. The BCM is typically located under the driver-side dashboard, near the steering column. It usually takes less than 15 minutes to unplug the old unit and install the new one. The key is ensuring your battery is disconnected before you begin.
Is this the correct part for my vehicle?
This Programmed 25844480 BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Suburban, Tahoe, Yukon, and Escalade. It replaces numerous original part numbers, including 25823559. Please verify the part numbers listed or use our vehicle fitment tool to confirm compatibility.
What if I need to perform a brake pedal position relearn?
On some models, a brake pedal position sensor relearn may be required after installation to ensure brake lights and traction control function properly. This is a simple procedure that can be performed with most bi-directional scan tools.
