Method for performing remote diagnosis of fault condition in car, involves sending control command to monitoring device for detecting trace data when no error class is found in diagnostic request

摘要

The method involves providing a monitoring device (24) in a car (10) for providing an error description (36) as well as error-state-independent metadata (38) of a current state of the car based on an error condition. A diagnostic request (42) is transmitted to a server (12), and the error description and metadata contained in the diagnostic request are compared. Error classes (46, 48) corresponding to known errors are stored in a memory (26). A control command (44) is sent to the monitoring device for detecting trace data (54) when no error class is found in the request. An independent claim is also included for a car.
