'''OBD''' (sigla [[Língua inglesa|do inglês]] ''On-Board Diagnostic'': "diagnóstico a bordo") e '''OBD-II''', é um sistema eletrônico de [[Diagnóstico|autodiagnóstico]] de [[veículo]]s; um recurso integrado ao computador de bordo na maioria dos automóveis que circulam atualmente, [[telemática]] e [[Internet das coisas|IoT]].<ref name=":0">{{citar web|url=https://www.geotab.com/pt-br/blog/obd-ii/|titulo=O que é OBDII? Histórico de diagnósticos a bordo|data=31 de julho de 2023|acessodata=7/08/2024|website=GeoTab}}</ref> As informações são geradas pelas unidades de controle do motor (ECU ou módulos de controle).<ref name=":0" />

A conexão ao sistema consiste em um conector padronizado que foi sancionado como obrigatório na [[Europa]] e nos [[Estados Unidos]] para todos os veículos produzidos desde 1996, e no [[Brasil]] a partir de 2010 com o padrão de segunda geração OBD2 (ou ODBII). A porta OBD-II pode ter uma configuração de 6, 9, à 16 pinos.<ref name=":0" />

A medida tem a finalidade de popularizar o serviço de reparo eletrônico, reduzindo drasticamente o custo das oficinas, possibilitando o consumidor pagar mais barato por esse gênero de serviço. Além disso, a padronização e abertura dos protocolos de comunicação trouxeram ao mercado equipamentos extremamente baratos possibilitando a compra dos mesmos pelos próprios consumidores para "diagnóstico em casa". Atualmente existem no mercado equipamentos de diagnóstico na ordem de $20 dólares com interface [[USB]] e tecnologia [[Bluetooth]] para sincronização com um computador ou aparelho celular.

== Versões ==
O OBD-II é a segunda geração do OBD, este era inicialmente conectado externamente ao console do carro, enquanto o OBDII é integrado dentro do veículo.<ref name=":0" />

[[EOBD]] (sigla do inglês ''European On-Board Diagnostics'', onde os automóveis a gasolina fabricados na Europa a partir de 2001 e os diesel desde 2003 devem ter sistemas de diagnóstico a bordo para monitorizar as emissões do motor.<ref>{{Citar web|url=https://www.gendan.co.uk/article_5.html|titulo=What is EOBD, EOBD2 and OBDII?|acessodata=2024-08-07|website=Gendan Automotive Products|lingua=en}}</ref>

[[WWH OBD|WWH-OBD]] (sigla do inglês ''World wide harmonized on-board diagnostics'': "diagnóstico a bordo harmonizado a nível mundial") é padrão internacional usado para o diagnóstico de veículos implementada pela [[Organização das Nações Unidas|ONU]], devido o mandato do Regulamento Técnico Global (GTR), este usa os Serviços Unificados de Diagnóstico (do inglês ''[[Unified Diagnostic Services]]'', UDS) com Códigos de Diagnóstico de Problemas (do inglês ''[[Diagnostic Trouble Codes]]'', DTC) de 3 bytes.<ref name=":0" />

== História ==
A idéia de diagnóstico a bordo é da década de 1960, quando várias organizações fizeram as bases para um padrão, como a California Air Resources Board (CARB), a [[Society of Automotive Engineers]] (SAE), a [[Organização Internacional de Normalização|International Organization for Standardization]] (ISO) e a [[Agência de Proteção Ambiental dos Estados Unidos|Environmental Protection Agency]] (EPA).<ref name=":0" />

Assim em 1968 a Volkswagen lançou o primeiro sistema de computador OBD com capacidade de digitalização do diagnóstico.<ref name=":0" /> Em 1979 a Society of Automotive Engineers recomenda um conector padronizado e um conjunto de sinais de teste DTC.<ref name=":0" />

== Informações ==
O OBDII tem acesso às informações de status e aos códigos DTC:<ref name=":0" />

* Veículos (motor e transmissão)
* Controle de Emissões

* Identificação do veículo
* Identificação da Calibração
* Contador de igniçãoModo 1: informação do veículo<ref name=":0" />

* Pid 12: RPM do motor
* Pid 13: Velocidade do veículo

Modo 3: problemas (P = Powertrain, C = Chassis, B = Body, U = Network)<ref name=":0" />

* P0201: avaria no circuito do injetor – cilindro 1
* P0217: temperatura do motor
* P0219: excesso de velocidade
* C0128: fluido de freio baixo
* C0710: avaria na posição do volante
* B1671: módulo de bateria de tensão fora de alcance
* U2021: dados inválidos

WWH UDS<ref name=":0" />

* P0070: temperatura do ar ambiente
* P0071: desempenho dos sensores de temperatura do ambiente
* P0072: pouca entrada no circuito do sensor de temperatura
* P0073: muita entrada no circuito do sensor de temperatura
* P0074: entrada intermitente no circuito do sensor de temperatura
