Greetings everyone. Wanted to help a friend out who has a 322C excavator, s/n HEK00257. He says it is running rough. He said he disconnected one injector at a time and whichever one didn't make it run harder would be the culprit. However, they all made it run worse, so he does not think it is an injector. We are wanted to access the ecm and see if there are any codes active. Can anyone instruct me how to do that without Cat ET? Thanks in advance.
