Hi all I am in a bit of a loose end. i have the above engine. and the yanmar i5601e display. I now have a loose end that i need help with if anyone can shed some light on. Engine has just done little over 100 hrs. Now i am getting check engine. now on the display this is all i am getting for some reason its not giving me the option to view diag codes. is there any reason why it's not letting me read the codes.engine is running smooth but when i push it to around 2500 revs it flashes check engine. i have striped the whole engine down. cleaned heat exchanges with riydelime. had turbo to be checked and its all working fine,elbow clean new fuel pump new temp sensor, new filters
It sounds like you're just pissing in the wind and throwing money at it. You need to get a Yanmar tech out with the yanmar computer.
