What is the issue when PRE-SAFE stops functioning

[Marie]

PRE-SAFE stops functioning under the following circumstances: 1. Normal situation: If PRE-SAFE stops functioning under normal circumstances, it does not affect the vehicle's operation. The driver can restore normal function by turning off the engine and restarting it. 2. Sensor malfunction: In special cases where it cannot be activated, it may be due to a sensor malfunction. It is recommended to take the vehicle to a 4S shop for inspection and check if the car radar needs cleaning; it is also possible that the camera sensor was damaged during car washing. 3. Safety protection device turned off: Additionally, PRE-SAFE stopping functioning could be due to the vehicle's safety protection device being turned off, meaning the passenger airbag switch is deactivated. The owner can go to a service station for assistance or manually turn on the passenger airbag themselves, with the switch located on the passenger side. If none of these issues are present, the owner can choose to upgrade the computer system and then clear the fault code.
