Remote diagnostics applications
There are multiple diagnostics application use cases – namely proximity, remote, and in-vehicle. In the proximity use case, the service technician uses their diagnostic tool and connects via a wireless or wired interface to the vehicle, in the remote use case, the technician connects via the cloud platform to the vehicle remotely, and in the in-vehicle use case, the vehicle dash or central-console interface is used for diagnostics. Figure 9.11 illustrates the proximity use case and remote diagnostics use case.

Vehicle diagnostics [2] can be classified into two types:
- Classic vehicle diagnostics based on Unified Diagnostic Services (UDS)
- Service-oriented vehicle diagnostics
While classic vehicle diagnostics rely on well-established protocols such as UDS, service-oriented vehicle diagnostics represent a more flexible and modern approach.
