Expert Insight: The End of the “Electrical Gremlin” Chase
As a technician, I’ve seen countless hours and dollars wasted chasing what seems like a dozen different electrical problems in these GM trucks.

Frequently Asked Questions
Do I need to take my vehicle to the dealership after installation?
No. This Body Control Module comes pre-programmed to your vehicle’s specific VIN. This allows for a direct, plug-and-play installation without the need for any additional programming from a dealership or mechanic.
What if my airbag light is on after installing the new BCM?
In some cases, particularly if you had an airbag code like B1001, the new BCM may need to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool.
Is this part difficult to install?
Installation is straightforward for most DIYers. The BCM is typically located under the driver’s side dashboard, near the steering column. It usually takes less than 10 minutes to swap out. Always disconnect the battery before starting any electrical work.
What is a core charge? Do I need to send my old part back?
A core charge is a deposit you pay until you return your old part. We do not have a core charge on this item, so you can keep your old BCM without any extra fees or hassle.
How do I know if this Programmed GM BCM 25844480 will fit my vehicle?
