This code means that there's a problem with the airbag system for the seat on the right side of the second row in your car. It's like a special pillow that's supposed to pop out in an accident, but something is wrong with it, and it might not work when needed.
The code B003B indicates an issue with the airbag deployment control system for the second row right seat. This is typically related to the airbag's ability to deploy in a staged manner during a collision.
The B003B code is triggered when the airbag control module detects a fault in the deployment circuit for the second row right frontal airbag, specifically in its stage 3 deployment. This could be due to electrical issues, such as an open circuit, short to ground, or short to voltage in the airbag deployment loop.
