Frequently Asked Questions
What is the main function of a Body Control Module?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like your lights, power windows and locks, security system, climate controls, and wipers, ensuring they all work together correctly.
Is this BCM difficult to install?
No, the physical installation is very straightforward for most DIYers. The BCM is typically located under the driver’s side dashboard near the steering column and can be swapped in under 5 minutes. Because our unit comes pre-programmed, no special computer tools are needed for the initial setup.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and configurations onto the module. Without it, the BCM won’t recognize your truck’s features, leading to incorrect operation or complete failure of certain systems. Our service ensures it works perfectly right out of the box.
Will this fix my airbag light that’s on?
This module can resolve BCM-related airbag codes like B1001. However, if the light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the new BCM with the airbag system. This is a common final step for this repair.
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 extra fees or hassle, making the replacement process even simpler.
How can I be sure this is the right 2007-2011 Silverado 3500 Body Control Module for my vehicle?
