The invention provides a redriving method and device of an actuator, electronic equipment and a computer storage medium, and the method comprises the steps: closing actuator driving when a fault diagnosis system reports fault information that the actuator has a physical line fault; then, after the driving control closing request is set to be 1, testing pulses are sent through the electronic control unit at preset time intervals; if the actuator responds to the test pulse within the preset number of times, it is indicated that misdiagnosis or physical line healing may occur, the drive control closing request is set to be zero, the application layer restores to drive the actuator, and the electronic control unit does not send the test pulse any more; if the actuator does not respond to the test pulse within the preset number of times, it is indicated that misdiagnosis is not carried out or the physical circuit cannot be cured, the electronic control unit does not send the test pulse any more, and the situation
