Frequently Asked Questions
What does a Body Control Module do on a Sierra 2500?
The BCM is a computer that manages and controls many of your truck’s non-engine-related electronic features. This includes the power windows, door locks, security system, interior and exterior lighting, wipers, and the HVAC system. When it fails, you can experience a wide variety of strange electrical issues.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before it ships. This allows it to communicate correctly with your truck’s other systems upon installation, eliminating the need for a trip to the dealership for expensive programming.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep or dispose of your original module, making the replacement process simpler and more convenient for you.
My airbag light is on after installation. What do I do?
In some cases, particularly if DTC B1001 was present, the new BCM needs to be synchronized with the airbag system’s SDM (Sensing and Diagnostic Module). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed with a professional-grade diagnostic scan tool. This is a simple sync procedure, not a full reprogramming.
How do I know if this BCM is compatible with my truck?
This module is a direct replacement for numerous part numbers and fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, and Escalade.
