Poor grounds are a common issue on these GM trucks and can mimic the symptoms of a failed module. When installing your new 2007-2011 Sierra 1500 Body Control Module, ensuring these grounds are clean and tight is a crucial step to prevent future problems.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this part really plug-and-play?
Yes. We program the module to the VIN you provide during checkout. This ensures it communicates correctly with your vehicle’s other computers right out of the box, with no additional programming required for standard operation.
What if my airbag light is on after installation?
In some cases, particularly if DTC B1001 was present, the airbag system (SDM) may need to be synced with the new BCM. This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool. This is the only potential post-installation step that may be required.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module without any penalty.
How do I know if this is the right BCM for my truck?
This 2007-2011 Sierra 1500 Body Control Module fits a wide range of GM trucks and SUVs.
