Diagnostics and Security: Gateways for hackers and how to close them – As long as diagnostics takes place locally, in other words using a cable connection between the diagnostic tester and the diagnostic interface or the vehicle, it is safe to assume that the diagnostic system is basically secure as far as unauthorized access is concerned. But the picture changes as soon as there is a remote data connection over the Internet.
A frequent challenge for diagnostics in the field, particularly in the machine environment, is that the ECU configuration of the machine is not known in advance and that a diagnostic project may have to be adapted or supplemented dynamically during runtime. With the new version 2.2. of the repair shop tool Softing TDX, it is possible to load and even supplement diagnostic projects dynamically, depending on the machine configuration.
Development projects are increasingly being handled by teams whose members are spread all over the world. Remote Engineering allows efficient networking of global work capacities. However, there are a number of aspects that need to be considered during implementation to ensure a smooth process.
ECU and vehicle updating is an important application area for Softing DTS.monaco, as an accompanying measure in the engineering process to validate various software versions, but also to prepare the automated flash procedure for manufacturing and after-sales service.
The visually meaningful representation of measurement parameters and their thresholds is necessary particularly at the test bench and in vehicle validation. Softing DTS.monaco helps visualize various states regardless of whether a NOx sensor has to fulfill its values within a certain time or if it has to be indicated that pressure or temperature has reached a threshold value.
The identification of a test unit as well as the reading out of the error memory are activities which are repeated throughout the product life cycle. Regardless of whether HiL, test bench or vehicle – the versions as well as any error memory entries which might occur must be acquired and documented in every test sequence.
During the life cycle of an ECU/vehicle, various diagnostic services and functions specified by the OEM or legislator have to be supported. Softing DTS.monaco can be used for a first step in this partly approval-relevant validation.
The book "Diagnostic Communication with Road-Vehicles and Non-Road Mobile Machinery" is all about standardized diagnostic communication between a diagnostic tester and E/E systems of road-vehicles and non-road mobile machinery such as agricultural machines and construction equipment.
Regardless of the integration level of software and ECUs, communication problems along the OSI communication layers result in specific challenges for diagnostic experts. These problems are critical for the remaining life cycle of the vehicle because, for example, in manufacturing, this behavior can lead to delays in or an entire absence of vehicle programming.
