What is the reason for the continuous flashing of hazard lights when the car is turned off?

The reason for the continuous flashing of hazard lights when the car is turned off is a problem with the control box. It is necessary to check whether the hazard light relay is functioning properly. Use a multimeter to directly measure the output line of the hazard light relay to see if there is a 12v output. If there is intermittent output variation, it indicates normal operation. If there is no output or a constant 12v output, it means the hazard light relay is damaged and needs to be replaced with a new one. The method to activate the hazard lights is to press the red triangle button on the vehicle's dashboard. The functions of hazard lights are: 1. To alert other vehicles in case of emergencies such as breakdowns or accidents; 2. To prevent rear-end collisions when parking on the roadside by turning on the hazard lights.
