Joel, think you are correct and understand we are not train mechanics and breaking out
Diagnostic Codes is getting into area where stress will over come problem at hand . Maybe
This will help clear up a few things. Caterpillar has what is called diagnostic codes and they
are listed in different ways so the operator can understand the seriousness of what is happening.
Number one active fault codes that are logged on engine ECM. What this means STOP ENGINE
and do not run until you can locate problem and or call tow truck. Number two, logged codes,
logged codes will show operator something been happening but is not active ( if Code is not active
do not worry about it. ) Number three, Event codes of which in about most all cases tell operator
What is going on but not a out of service. What event code means just what it says , an event
Has taken place but may come and go. ( like a short on switch, comes and goes or dirty electrical
Connection ). The diagnostic readout ECM will tell a person engine hour clock time, occurrence
first time and last time engine clock and total occurrence.for example heat sensor occurrence 178
times will pin point electrical short of faulty heat sensor. Last this is called a logged event code.
many event codes will clear after 100 miles. Again misunderstanding in areas that require a trained
Technician can be sometime very stressful. Myself with all these different monitors on your dash
to help you understand your engine while driving a person needs to understand your Caterpillar
engine has all the fail safe built into engine to protect engine. Dave Atherton Retired Cat Mechanic
