Can you supply any more details of the Diagnostic Code(s) .? The Operator Monitor can be used to pull off more detailed information. Are we talking about a dealer mechanic here.?
Thanks I’ll put a detailed put together. Here is the entire serial number in the attached photo.
Yes CAT dealer’s mechanic located in Vernal Utah USA.
20 year experience CAT service mechanic tried to update ECM engine control module but this unit can not be updated. Monitor in cab shows a red exclamation ❗️ flashing at top of monitor and in the lower portion of monitor message says Engine Fault Check Engine. This machine doesn’t show the Diagnostics on the menu. The mechanic said first error code said replace mass error sensor. That was replaced last week. Then the second error code said to replace the crank sensor. After both brand new sensors were replaced still having same problem but no more error codes. Machine drops from 70hp to 40HP and shuts down. Machine was running fine before this initial error code. Thank you
Without knowing details of what specific Diagnostic Codes are/were present any suggestions would be a cr@p shoot IMHO. Can you get hold of the mechanic and ask him for some details of what the Codes were.? If he was following standard protocol he should have downloaded a Product Status Report (PSR) before he started any diagnostics. The PSR is an Adobe pdf document and would contain details of all Codes/Events that were regaistered in the machine ECMs. Please ask him if he has that document.
Yes will contact CAT mechanic on Monday and request this information. I’ll post again Monday with this info. Thank you
