Abstract

A method for diagnosing a state in a vehicle, which has a CAN communications bus to which electronic control units of the vehicle are connected, includes providing a rest state of the vehicle; coupling a diagnostic testing device to at least one diagnostic terminal of the vehicle; monitoring of the CAN communications bus by the diagnostic testing device with regard to CAN messages sent out after entry into the rest state; detecting of a CAN message sent out on the CAN communications bus after entry into the rest state, and assigning of the detected CAN message to an electronic control unit sending out the CAN message; providing information regarding a chronological appearance of the detected CAN message in a series of CAN messages appearing on the CAN communications bus after entry into the rest state; and providing information for identifying the electronic control unit sending out the detected CAN message.
