Expert Insight: Check Your Grounds First!
As a veteran technician, I’ve seen countless BCMs replaced when the real culprit was a poor ground connection. On these GM trucks and SUVs, the main ground point is often located on the frame rail beneath the driver’s door. Before installing your new programmed GM 25844480 BCM, take 10 minutes to locate, remove, and clean this ground connection with a wire brush until it’s shiny. A solid ground is critical for the BCM to function correctly and can prevent a host of electrical issues from returning.
Frequently Asked Questions
Does this BCM really not require any programming at the dealership?
That’s correct. We program the module to your vehicle’s VIN before it ships. This allows for a straightforward installation where you simply disconnect the old BCM and connect the new one. No dealer visit is required for the BCM itself to function.
What tools do I need for installation?
Installation is typically very simple and requires basic hand tools, such as a socket set or nut driver, to remove the lower dash panel for access. The BCM is usually held in place by clips or a few small bolts and is located under the steering column.
My airbag light is on. Will this fix it?
This module will often resolve the underlying electrical fault causing an airbag light (like DTC B1001). However, in some cases, a post-installation procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to sync the new BCM with the airbag system and turn off the light.
What if this module doesn’t fix my problem?
While a faulty BCM is the cause of these symptoms in the vast majority of cases, we recommend proper vehicle diagnosis. If you install the module and your issue persists, you may have a different problem, such as a wiring short or a bad ground connection. This unit is backed by our one-year replacement warranty for any defects with the part itself.
Is this a new or used part?
This is a high-quality, OEM-grade component that has been thoroughly tested and prepared to provide reliable, long-term service for your vehicle. It is programmed with the latest GM software updates for optimal performance.
