On-board diagnostics. Various views of a "MaxScan OE509" – a fairly typical onboard diagnostics (OBD) scanner, 2015. On-board diagnostics ( OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that ...
OBD-II PIDs. OBD-II PIDs ( On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [1] It is derived from ISO 14230-3 and the now obsolete ISO 15765-3 (Diagnostic Communication over Controller Area Network (DoCAN) [2]). 'Unified' in this context ...
The International Classification of Diseases, Clinical Modification (ICD-9-CM) was an adaptation created by the US National Center for Health Statistics (NCHS) and used in assigning diagnostic and procedure codes associated with inpatient, outpatient, and physician office utilization in the United States. The ICD-9-CM is based on the ICD-9 but ...
Classical (algebraic) block codes and convolutional codes are frequently combined in concatenated coding schemes in which a short constraint-length Viterbi-decoded convolutional code does most of the work and a block code (usually Reed–Solomon) with larger symbol size and block length "mops up" any errors made by the convolutional decoder ...

SNOMED started in 1965 as a Systematized Nomenclature of Pathology (SNOP) and was further developed into a logic-based health care terminology. [6] [7]SNOMED CT was created in 1999 by the merger, expansion and restructuring of two large-scale terminologies: SNOMED Reference Terminology (SNOMED RT), developed by the College of American Pathologists (CAP); and the Clinical Terms Version 3 (CTV3 ...
When a vehicle detects a problem, it generates a DTC code which is a unique code that corresponds to the specific problem detected. The code is usually a combination of letters and numbers. DTC codes are read by a diagnostic tool, such as an OBD 2 scanner, which is plugged into the vehicle's diagnostic port. The tool communicates with the ...
