Is there a certain temperature required (for the machine/engine to warm up to) before reverse works? I was out riding and went to reverse and no go. This was the first time I have ever used the reverse on this new machine, a 2021 Expedition SE 900 ACE. After I pressed the button to go into reverse, I just heard some clunking sounds then a RER Failure message came up on the display.
I tried a few more times, same thing. I tried in neutral, 1st, and 2nd. Same thing. You can see engine temp (I think?) in attached photo with the RER failure message. It was minus 15 F (15 degrees F below zero, or about minus 26 C) outside at the time. No snow or ice build up at all on the track. The machine was on fairly level, hard pack snow ground (snow covered dirt road). I had ridden the machine about .9 miles before trying reverse. The display readout showed 169F for engine temp.
I drove back home and tried it again and then reverse worked without issue, several times. Weird. I didn't happen to notice or get a photo of the display when the reverse did work, so didn't notice the engine temp readout at that point.
Thoughts? Anyone else experience this? What could cause this?
