Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this module truly plug-and-play?
Yes. Because we program the module to your vehicle’s specific VIN before shipping, it is ready for installation right out of the box. In most cases, no further steps are needed. However, please see our note about the airbag system.
What if my airbag light stays on after installation?
If the airbag warning light is on after installing the new BCM (often with code B1001), a procedure called “Setup SDM Primary Key in BCM” must be performed. This requires a professional-grade scan tool and syncs the new BCM with the airbag system. This is the only potential post-installation procedure that may be required.
Do I need to return my old BCM?
No. We do not require a core return for this part. You can keep or dispose of your old module, making the replacement process even simpler and more convenient.
How can I be sure my BCM is the problem?
A failing BCM typically causes multiple, seemingly unrelated electrical issues. If your power locks, windows, and HVAC are all acting up, the BCM is the most likely culprit. The 2007-2011 Sierra 1500 BCM 25790508 is the direct solution for these widespread symptoms.
Will this fit other GM models besides the Sierra 1500?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Tahoe, Suburban, Yukon, and Escalade. Please refer to the detailed fitment list on this page to confirm compatibility with your specific vehicle.
