This code means there's a problem with the airbag system in the car, specifically the part that controls how the driver's airbag deploys in a crash.
The vehicle's airbag system has multiple stages for deploying airbags. This code indicates an issue with the third stage of the driver's frontal airbag deployment.
The B0003 code is triggered when the airbag control module detects a fault in the circuit responsible for the third stage deployment of the driver's frontal airbag. This can be due to a malfunction in the control module, wiring, or connectors.
• Airbag warning light on the dashboard
• Airbag may not deploy properly in a crash
• Potential error messages on diagnostic tools
• Faulty airbag control module
• Damaged wiring or connectors
• Corroded or loose connections
