3 Terms, definitions and abbreviated terms

3.1 Terms and definitions

For the purposes of this document, the following terms and definitions given in ISO 27145-1 and ISO 14229-1 apply.

3.1.1 calibration identifier: CALID

identification code for the software installed in the electronic control unit

3.1.2 calibration verification number: CVN

server/ECU calculated verification number used to verify the integrity of the software in the electronic control unit

3.1.3 central gateway: CGW

electronic control unit that connects in-vehicle communication networks

3.1.4 data identifier: DID

indicator making reference to a data item in the server

3.1.5 diagnostic trouble code: DTC

value making reference to a specific fault in a system implemented in the server
Note 1 to entry: It is defined in SAE J2012-DA or as SPN and FMI as defined in SAE J1939 Companion Spreadsheet and SAE J1939-73:2010, Appendix A.

3.1.6 info type identifier: ITID

indicator making reference to identification information
EXAMPLE:Calibration identifier in the server.
Note 1 to entry: The ITIDs are defined in SAE J1979-DA.

3.1.7 malfunction indicator: MI

display or gauge that clearly informs the driver of the vehicle in the event of a malfunction/failure
Note 1 to entry: Additional details are included in the WWH-OBD GTR.

3.1.8 monitor identifier: MID

indicator making reference to an OBD monitor function
Note 1 to entry: An example of an OBD monitor function is a misfire monitor in the server. The MID is defined in SAE J1979-DA.

3.1.9 standard/manufacturer monitor test identifier: SMTID

OBD identifier which is defined in SAE J1979-DA or by the vehicle manufacturer

3.1.10 parameter identifier: PID

unique identifier used to refer to a specific data value within a server

3.1.11 routine identifier: RID

identifier making reference to a routine function
Note 1 to entry: An example of a routine function is an evaporation monitor routine in the server.
Note 2 to entry: Routine identifiers are defined in SAE J1979-DA.

3.1.12 suspect parameter number: SPN

numeral that identifies a particular element, a fault associated with a component, such as a sensor, or a parameter associated with an ECU

3.1.13 uniform resource locator: URL

uniform resource identifier which, in addition to identifying a resource, provides a means of locating the resource by describing its primary access mechanism
Note 1 to entry: An example of primary access mechanism is its network location.
