Expert Tech Tip: Check Your Grounds!
From my 20+ years under the dash, I can tell you that a bad ground is a common culprit for BCM failure and can cause a new module to fail prematurely. Before installing your new BCM, take a few extra minutes to inspect the main grounding points under the dash near the driver’s side kick panel. Ensure they are clean, tight, and free of corrosion. This simple step can prevent a world of headaches and ensure your new GM 25844480 Body Control Module provides years of flawless service.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It reads inputs from switches (like your window or headlight switch) and sensors, and then sends commands to operate things like your lights, wipers, power locks, windows, HVAC blower motor, and security system.
Is this module truly ‘plug-and-play’?
Yes. Because we program the module to your vehicle’s VIN before shipping, it will be recognized by your truck’s other computer systems upon installation. This allows you to skip the expensive programming procedures required at a dealership.
What if my airbag light stays on after installation?
If the airbag light persists (often with code B1001), it means the new BCM needs to be synced with the airbag’s computer (SDM). This is not a defect. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure, which is a quick recalibration that resolves the light.
Do I need to return my old BCM?
No. There is no core charge or requirement to return your original part. You can keep it or dispose of it at your convenience.
How can I be sure this part fits my vehicle?
This BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade.
