We are trying out a 320 Cat Next Gen, and it has 2 codes on the display. I have kept away from emissions machines, and electronic control hydraulics, and Can Network electronics, so this would be the first foray into these machines, it has two codes on the display, 4576-3(1) 2402-9(1) Is there a maintenance mode to access in the display to read these codes? What are these codes? and what is the typical issue? Are these decent machines? S/N 320CMYK00188
