Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we pre-program the module to your vehicle’s VIN before shipping. This allows for a plug-and-play installation without the need for expensive tools or a trip to the dealership.

Installation is typically very simple, requiring only basic hand tools like a socket set or screwdriver to remove the lower dash panel. The module itself is held in by clips or a few small bolts and has several electrical connectors that unplug easily.
Will this fix my airbag light?
This BCM can resolve issues causing an airbag light, especially if you have DTC B1001. However, in some cases, a post-installation procedure called “Setup SDM Primary Key in BCM” may be required using a professional scan tool to sync the new BCM with the airbag system and turn off the light.
