- Faulty weight sensor: There is a weight sensor in the passenger seat that determines whether or not the airbag should be activated. If this sensor is faulty, it may be sending an incorrect signal to the airbag control unit, causing the airbag light to stay on.
- Loose or disconnected wiring: The passenger airbag system relies on several electrical connections to function properly. If any of these connections are loose or disconnected, it can prevent the system from functioning correctly and cause the airbag light to stay on.
- Faulty airbag control unit: The airbag control unit is the central computer that manages the airbag system. If this unit is faulty, it may cause the airbag light to stay on, even if there are no other issues with the system.
To diagnose the exact cause of the passenger airbag light staying on, it is recommended that you take your vehicle to a qualified mechanic or automotive technician. They will be able to use diagnostic tools to identify the specific issue and make any necessary repairs.
