METHOD FOR THE SAFE DEACTIVATION OF A HIGH VOLTAGE NETWORK OF A MOTOR VEHICLE

摘要

The invention relates to a method for the safe deactivation of a high voltage network (3) of a motor vehicle (1) during a diagnosis and/or repair procedure. According to said method, a first operating action is carried out on operating elements of the motor vehicle (1) and/or an external testing device (22) connected to a bus system (20) of the motor vehicle (1), thereby transmitting a first trigger signal to the bus system (20) of the motor vehicle (1). When at least one control appliance (14-19) of the motor vehicle (1) receives the trigger signal, the high-voltage network (3) is deactivated such that it can only be reactivated by a second trigger signal generated by a defined second operating action.
