Eso de escanearlo me intereso, como lo puedo hacer 
saludos |
AQUI ESTA CON UN SIMPLE CLIP SE AHORRAN UNAS LUKAS solo para los 22RE
Unir como se muestra los terminales "E1" con "TE1" con la chapa de contacto en "off" luego das contacto y veras que se enciende la luz del check engine ...................infinitos parpadeos seguidos significa que
no hay codigo de fallas.
ahora un parpadeo de la luz "check engine" seguido de una pausa serian 10(decenas) y los parpadeos seguidos serian 1 (unidad)....haber si me explico...........
@...........=10
@...........@@=12 entiendase @=parpadeo luz check engine
@......@.......@=21
@......@.........@@=22
@......@.........@..........@@@@=34
Y asi sucesivamente ahora una vez que tiene el numero revisar la sgte tabla:
