O OBD Diagnostice |
|
Basically OBD is invented to monitor the emission-relevant systems and to secure are constantly low emissions. Should one of the involved components fail or is showing a malfunction, the event is saved and depending on the relevance for the environment corresponding actions are taken. So a single ignition failure will have no consequences for normal driving operation as far as possible. However it will be saved and can be read out via the OBD interface. In case of a more severe event, e.g. the failure of the lambda probe, permanent ignition failures etc. an emergency program is started that makes it possible to read the next garage on own resources.
The manufactures started very soon to make other systems and their errors readable via OBD. This went so far, that currently nearly everything could be read out, set and reset via the OBD interface. E.g.: In cars of the VAG company one can already set the reaction of the central locking system (when the key switch is pressed, should the windows close or not, same for the sunroof), via the comfort function; one can also set the displays in the dashboard, the air condition, the gear reaction of the automatic shift, the sound settings of the radio, etc. Even the emission check and the setting of the CO2 values can be done via the OBD interface.
Otázkou zůstává jaké diagnostické možnosti mám ve svém vozidle, jaké řídící přístroje jsou zabudovány, co lze všechno nastavit, jaký hardware a software potřebuji, abych si mohl se svým autem dělat věci, které chci.
Pro diagnostiku musíme v prvé řadě vědět, jestli je konkrétní vozidlo vybaveno OBD I nebo OBD II . Pak je otázkou, jestli se má provádět čistě diagnostika nebo také chiptuning a tacho nastavení. Z toho vychází výběr hardware. Přitom je třeba vzít v úvahu, že ne každý hardware ( Interface) spolupracuje s jakýmkoliv softwarem. Abyste zjistili diagnostické schopnosti vašeho auta, tak si projděte téma OBD-Technik a případně zapojení zásuvky. |
