CAT 299D3 (DY9) slightly revs up and it sounds like the hydraulic fan revs up a little bit right after to turn the key to the off position. I'm going to calibrate the fan today, but beings there is no codes I wondered if this was a normal procedure and what the point of it is. I also have two more of these 299D3's and neither of them have this issue. Any advice would be appreciated.
