Frequently Asked Questions
What does a Body Control Module do on a Chevy Tahoe?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lights, the security system, wipers, and the HVAC system, ensuring they all work together correctly.
Is this BCM truly “plug and play”?
Yes. We program the module to your vehicle’s VIN before shipping it. This ensures it communicates correctly with your truck’s other computers right out of the box, eliminating the need for any additional dealership programming.
Do I need to send my old BCM back?
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 simpler for you.
Will this fix my airbag light?
In many cases, yes. However, if the airbag light remains on after installation, a simple “Setup SDM Primary Key in BCM” procedure may be needed. This is a quick sync that can be performed with a professional scan tool to finalize communication between the new BCM and the airbag system.
