Expert Technician’s Tip: When replacing any major electronic module like a BCM, always take an extra minute to check the main ground connections on the chassis nearby. A loose or corroded ground wire is a common culprit for repeat failures and can cause symptoms that mimic a bad module. Ensuring a clean, tight ground connection is a simple step that can save you a world of headaches down the road.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like your power windows, locks, lights, wipers, security system, and climate controls, ensuring they all work together correctly.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The module is usually located under the driver’s side dashboard or steering column and can often be replaced in under 15 minutes. Because it comes pre-programmed, no special computer tools are needed for the initial setup.
Will I need to go to the dealer after installation?
No. The primary benefit of our module is that it’s programmed to your VIN before shipping. This means you can skip the expensive and time-consuming trip to the dealership for programming that is required with a new, un-programmed module.
What if my airbag light stays on after installing the new BCM?
In some cases, particularly if you had an airbag code like B1001, the new BCM needs to be electronically introduced to the airbag system (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed with a professional-grade scan tool. This syncs the systems and turns off the light.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and return shipping costs.
How do I know this is the right 2007-2011 Sierra 2500 Body Control Module for my truck?

When you provide your VIN at checkout, we perform a final verification to guarantee you receive the correct, pre-programmed part for your specific vehicle.
