Securely providing diagnostic data from a vehicle to a remote server using a diagnostic tool

A vehicle system and method of secure communication between a vehicle and an external device communicating with the vehicle in a diagnostics mode. The method includes the steps of: receiving a first diagnostic request at an electronic control unit (ECU) from the external device; determining an increased risk of security breach at the ECU based on the [nature of the] first request; and when it is determined that the increased risk exists, providing a misinformative response.
