ISO 9141-2 utiliza comunicaci\u00f3n serie as\u00edncrona a trav\u00e9s de uno o dos cables (l\u00edneas K y L) para transmitir datos. La velocidad de transmisi\u00f3n es de 10,4 kb\/s, lo que resulta suficiente para diagn\u00f3sticos b\u00e1sicos, lecturas de sensores y obtenci\u00f3n de c\u00f3digos DTC. El protocolo tambi\u00e9n incluye procedimientos de inicializaci\u00f3n y sincronizaci\u00f3n (handshake), que garantizan una transmisi\u00f3n de datos estable y reducen la probabilidad de errores.<\/p>\n\n\n\n
