345CL PJW00920 6363hours 6329 hrs@ startup, "ENGINE ECM ERROR" in red on screen. Active errors 36:268-2 programmed parameter fault. 105:590-12 ECM fault. No Events. Machine ran normal. Dealer reflashed ECM. Machine now normal, and display normal. 6mos later, 6363 hrs@ startup, "ECM FAULT" in red onscreen. Active errors 36:268-2 105:590-12 Now has logged Event 105:E00179 The first and last occurrences are way outside the current or past meter reading. AND, now any function that uses pump #1 chatters and shakes whole machine. Pressure jumps all over the place only on pump #1. Pump #2 responds normal. Obviously, the ECM has forgotten its values again, but, what would screw with pump #1 operation? Machine did sit unused for 4 years, with only an occasional startup.
Disregard. ECM needs replaced. Main pump #1 shed most of it's brass.
I had a few medium HEXs with ECM problems several years ago. Like yours they would lose software settings or sometimes engine ECMs would lose FLS and FTS values. The only solution appeared to be ECM replacement.
Yup. FLS & FTS lost, again. Hydro pump had a service letter EIGHT years ago. Gonna cry to Cat and see if any help is available.
If you get ANY assistance then you better head to the nearest casino............and bet the farm.
You might get some deep sympathy, an estimate for half the real cost and a handkerchief to cry in.
What does the oil analysis history show? If you can demonstrate elevated wear levels whilst the service letter was still current, you may have a chance.
What did you ultimately end up doing to fix your machine? I have the same machine with 7900 hours and had the codes read last fall same as yours, I acquired this machine last summer and same as yours sat for like 7 years with only occasional starting but no really use. I changed all the hydraulic filters and no metal visible. Thanks
Limped it on a trailer and traded it in for a 325F.
