Desarrollo Hacia Adentro Desarrollo Hacia Afuera

El procedimiento es el siguiente:

- Apagar el contacto del auto.
- Buscar debajo de la guantera una ficha color celeste con 2 ranuras planas y puentearla con un cable.
- Poner el auto en contacto.
- La Luz amarilla que se encontraba prendida va a empezar a hacer una serie de destellos largos y luego una serie de destellos cortos. Contar cuantos hace de cada uno.
-Los destellos largos sonlas decenas y los cortos son las unidades.

Ejemplo:
6 destellos largos, 7 destellos cortos significa codigo de error 67 
Busco en la tabla y la falla es "baja eficiencia del catalizador o catalizador roto"
