Throwing U0300 codes on both engines. Turns over fine but will not start. Does anyone have any ideas?
 
U0300 is the loss of the security coding in the cluster/touchscreen. The engines will just roll over if the ECMs dont see this coding.

Thanks. Do you know how to fix this?
 
BUDS will have to be hooked up and they will need to have the ECMs relearn the coding.
Unsure if this can be done with Can-doo.

Thanks! CanDoo cannot do this. However, I got it fixed. The cluster had to be re-paired with the ECM. Micah from FB posted how to do this. I followed his instructions and it worked. Can't believe I lost the whole day :banghead: but at least it's fixed. :thumbsup:
 
Micah to the rescue again :thumbsup:. He's help me out as well on the Vortex FB site.
Yes, great guy, very knowledgeable with these boats. Speaks well and is always willing to help. Need more people like him...

Hi cann you tell me the instructions haw to do that. Thanks Branko
 
¡Gracias! CanDoo no puede hacer esto. Sin embargo, lo arreglé. Tuve que volver a emparejar el clúster con el ECM. Micah de Facebook publicó cómo hacerlo. Seguí sus instrucciones y funcionó. No puedo creer que perdí todo el día, :cabeza de ganso: pero al menos está arreglado.:Pulgares hacia arriba:
Disculpa tengo una chaparral 2016 y la falla que me hace es que al arrancar a los 5 segundos se apagan ambos motores. Y después ya no quieren arrancar. En candoo me arroja el código u0300 pero no me arroja la opción para enlazar los ecu con el cluster. Será la misma falla que tú tenías ?
