Recently had some hydraulic lines replaced at a local shop. The machine was there for about 3 months before they could get to it, order the parts, and get it done. Once I got it back, I've gotten several codes and it begins to derate. Also, when I start it up now it states something like "unknown model". 237.13 523935.05 1569.31 94.04 523941.05 Today I changed both fuel filters and still getting 2 codes and it still derates: 237.13 Vehicle Identification Calibrate error 1569.31 Engine Protection Derate Any thoughts on next step?
Please post the machine's serial number. So, all those codes cleared and the two at the bottom were the only ones to return? The most likely resolution is to have both the EMU and the ECU reprogrammed, then let the machine run for 15 minutes after that.
