DoIP	Diagnostics over Internet Protocol (Communication protocol of automotive electronics according to ISO-13400[5])
Aging	Unlearning/deleting of a no longer failed event/DTC after a defined number of operation cycles from event memory.
Diagnostic Client	A Diagnostic Client is a diagnostic service requester, i.e. sends a UDS request to the Diagnostic Server. Usually the Diagnostic Client is an external tester equipment but can also be another vehicle internal ECU.
Diagnostic Communication Management	Diagnostic Communication Management is the part of the Diagnostic Management which belongs to tester communication and the processing of UDS services.
Diagnostic Conversation	Diagnostic Conversation represents a conversation between Diagnostic Client (Tester) and Diagnostic Server.
Diagnostic Event Management	Diagnostic Event Management is the part of the Diagnostic Management which belongs to processing and storing of diagnostic events and associated data.
Diagnostic Management	Diagnostic Management is a placeholder for the complete functionality of diagnostic communication and event handling.
Diagnostic Server instance	Diagnostic Server (DM) is intended to support an own Diagnostic Server instance per installed SoftwareCluster, see section 7.5 for a detailed description. Each of those Server instances has and manages its own resources and is responsible for dispatching and processing of diagnostic services.
Diagnostic Service instance	A diagnostic service instance implements a concrete use of a diagnostic service in a given context. It refers to a DiagnosticServiceClass and the DiagnosticAccessPermission , see 7.5.1.5.3 for a detailed description.
Displacement	In case of an Event memory overflow: Replacing the most insignificant stored event memory entry by a reported event which needs to be stored and is more significant.
DTC group	Uniquely identifies a set of DTCs. A DTC group is mapped to the range of valid DTCs. By providing a group of DTCs it is expressed that a certain operation is requested on all DTCs of that group. The DTC group definition is provided by ISO 14229-1[1] and OEM/supplier-specific.
DTCStatusAvailabilityMask	The DTCStatusAvailabilityMask - byte is used in UDS responses to requests for certain sub-functions of service 0x19. It express which of the UDS DTC status bits are supported by the DM for masking purposes.
Enable Conditions	The criteria / conditions under which the test results from the monitors in the AA’s are valid and shall be processed by DM. Configuration is done per event.
Extended Data Records	Contains statistical data for a DTC. Extended data records are assigned to DTCs and maintained and stored by the DM.
Event	An event (also diagnostic event) uniquely identifies a fault path of the system. An application monitors the system and reports events to the DM.
Event memory	The DM stores information about events in the event memory. There can be multiple event memories, each keeping information independently from each other. Examples of the event memory is the UDS primary event memory or the up to 256 user-defined event memories.
Event memory overflow	An event memory overflow occurs, if this specific event memory is full and the next event occurs to be stored in this event memory.
Event status	Bit-packed status information based on Event level. Contains the following bits: Nr. Definition: • 0 testFailed • 1 testFailedThisOperationCycle • 6 testNotCompletedThisOperationCycle Compare UDS DTC status bit
Fail-safe reaction	(Sometimes also called "limp home mode"): Reaction to avoid or minimize harm or damage in case of a failure.
GroupOfAllDTCs	Identifies a special DTC group that contains all DTCs. This DTC group is identified by the DTC value 0xFFFFFF in 14229-1[1] and contains by default all DTCs of a fault memory. It is present by default in the DM and requires no configuration.
Internal, External	Classifies if a DiagnosticDataElement is either managed internally inside DM or by an external adaptive applications, see 7.5.4.1 for the precise definition.
Internally, Externally	Definition of the support type of a SID by the DM. Internally means processing is done by DM itself, Externally means an external service processor is used.
internal data element	A DiagnosticDataElement which is provided by the DM itself. See also 7.5.4.1.
Monitor	A monitor (also diagnostic monitor) is a piece of software running within an application, monitoring the correct functionality of a certain system part. The result of such a function check is reported to the DM in form of a diagnostic event.
Operation cycle	A new operation cycle is the start of a new monitoring cycle. This is reflected in a reset of the testFailedThisOperationCycle and testNotCompletedThisOperationCycle bits in the DTC status and optional notification to the monitor to restart the monitoring.
Primary event memory	The primary event memory is used to store events and event related data. It is typically used by OEMs for after sales purposes, containing information to repair the vehicle.
Snapshot Record	Set of measurement values stored in the fault memory at a certain point of time during fault detection. It is used to gain environmental data information for occurred faults.
SoftwareCluster	A SoftwareCluster groups all AUTOSAR artifacts which are relevant to deploy software on a machine. This includes the definition of applications, i.e. their executables, application manifests, communication and diagnostics. In the context of diagnostics a SoftwareCluster can be addressed individually by its own set of diagnostic addresses.
SourceAddress	A Source Address is used to encode client and server identifiers. In a UDS request the source address encodes the Diagnostic Client whereas the source address in a UDS response encodes the Diagnostic Server.
TargetAddress	A Target Address is used to encode client and server identifiers. In a UDS request the target address encodes the Diagnostic Server whereas the target address in a UDS response encodes the Diagnostic Client.
Transport Protocol Handler	A subcomponent of DM implementing a particular Transport Protocol (either DoIP or any other proprietary UDS Transport Layer).
Transport Protocol Manager	Link between UDS Transport Layer and Application Layer.
UDS service	A diagnostic service as defined in ISO 14229-1[1].
UDS DTC status bit	UDS DTC status bit as defined in ISO 14229-1[1] Annex D.2; Each single bit position represents and documents a certain status information for the connected DTC. The following eight bits are defined: Nr: Definition: 0 testFailed 1 testFailedThisOperationCycle 2 pendingDTC 3 confirmedDTC 4 testNotCompletedSinceLastClear 5 testFailedSinceLastClear 6 testNotCompletedThisOperationCycle 7 warningIndicatorRequested All eight bits constitute the UDS DTC status byte. Compare Event status
UDS DTC status byte	Bit-packed DTC status information byte as defined in ISO 14229- 1[1], based on DTC level. Contains the UDS DTC status bits.
User-defined event memory	The user-defined event/fault memory is used by the UDS service 0x19 with subfunctions 0x17, 0x18 and 0x19. It behaves as the primary event memory but contains data independent from the primary fault memory. It is used to store information that are relevant for different purposes such as warranty or development.
Non-volatile Memory	In the context of DM, Non-volatile Memory refers to the persistent information over the shutdown of the DM process. This does not depend on HW details.
