Terms and Definitions
3.1.1 calibration identifier, CALID
identification code for a specific software/calibration contained in a server/ECU
Note 1 to entry: If regulations require calibration identifications for emissions-related software, these are reported in a standardized format as specified in ISO 27145-2.
3.1.2 class A, B1, B2, C malfunction
attribute of a DTC, which characterizes the impact of a failure on emissions or on the OBD system's monitoring capability according to the requirements of the WWH-OBD GTR
3.1.3continuous malfunction indicator, continuous-MI
malfunction indicator showing a steady indication at all times while the key is in the on (run) position with the engine running [ignition ON - engine ON]
3.1.4 continuous malfunction indicator counter, continuous-MI counter
conveys the amount of time the OBD system was operational during the time a continuous-MI was last activated
Note 1 to entry: For a detailed definition, see GTR No. 5.
3.1.5 confirmed and active DTC
DTC status, which is detected during two consecutive operation cycles, in which the DTC is still present and commands the MI to be on if the DTC class is A, B1 or B2
Note 1 to entry: For a DTC of class C, the MI is not illuminated.
3.1.6 cumulative continuous malfunction indicator counter, cumulative continuous-MI counter
cumulated operating hours with a continuous-MI activated
Note 1 to entry: The cumulative continuous-MI counter counts up to the maximum value provided in a 2-byte counter with 1 h resolution and holds that value. The cumulative continuous-MI counter is not reset to zero by the engine system, a scan tool or a disconnection of a battery.
The cumulative continuous-MI counter operates in the following manner:
a) the cumulative continuous-MI counter begins counting once the continuous-MI is activated;
b) the cumulative continuous-MI counter halts and holds its existing value once the continuous-MI is no longer activated;
c) the cumulative continuous-MI counter continues counting from the point at which it had been held when a continuous-MI was activated.
3.1.7 calibration verification number, CVN
server/ECU calculated verification number used to verify the integrity of the software/calibration contained in a server/ECU
Note 1 to entry: If regulations require calibration identifications for emissions-related software, those are reported in a standardized format as specified in ISO 27145- 2.
3.1.8 discriminatory display
requires the MI to be activated according to the class in which a malfunction has been classified
3.1.9 malfunction
failure or deterioration of a vehicle or engine system or component, including the OBD system, during which the WWH-OBD GTR specifically identifies the conditions which are considered to be failures
3.1.10 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.
3.1.11 malfunction indicator counter, MI counter
conveys the amount of time during which the OBD system operates while a failure/breakdown is active
3.1.12 non-discriminatory display
indicator requiring only a single type of MI activation
3.1.13 on-board diagnostics, OBD
system that monitors some or all computer input and control signals
Note 1 to entry: Signal(s) outside of the predetermined limits imply a fault in the system or in a related system.
3.1.14 previously active DTC
DTC status that is first detected during two consecutive operation cycles but later detection shows that the fault is no longer present
3.1.15 vehicle identification number, VIN
numeral identifying and specific and unique to each vehicle according to the applicable legal provisions of each national/regional authority
3.1.16 vehicle on-board diagnostics
providing a single access point for external test equipment to retrieve all data of the OBD system
3.2 Abbreviated terms

CVN calibration verification number
DTC diagnostic trouble code
DID diagnostic data identifier
DLL data link layer
ECM engine control module
