Frequently Asked Questions
What does a BCM do on my Sierra Denali?
The Body Control Module, or BCM, acts as the central computer for your truck’s body electronics. It manages non-engine related functions like your interior and exterior lights, power windows, door locks, security system, wipers, and the HVAC climate control system.
Is this module truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it’s ready for installation without requiring any additional programming from a dealership, saving you time and money.
What if my airbag light stays on after installation?
In some cases, particularly if DTC B1001 was present, the airbag system 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 diagnostic scan tool. It is only necessary if the airbag light remains on after the new module is installed.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module without any obligation to return it.
Where is the BCM located in my truck?
The BCM is typically located inside the cabin, under the driver’s side of the dashboard, often near the steering column. Installation is straightforward and usually takes less than 15 minutes.
Will this fix a specific DTC like B1001?
Yes, a faulty BCM is a very common cause for the DTC B1001 (Option Configuration Error). Replacing the module with this correctly programmed unit is the standard procedure to resolve this code, though you may need to perform the SDM key sync procedure as mentioned above.
