Installed the G8 gauge on a M sno pro 858 a week ago. Fired the sled up, gauge worked great everything works, no codes. Went to load the sled in the trailer for a trip this weekend and noticed the check engine light came on. I have the registration code U1000 on still have to get that done. Is there a way to look up what the check engine is on the G8 without it running? I tried toggling through the diagnostic page after I shut the sled off and didn't see anything. There was no additional code beside U1000 shown on gauge when it was running, just that and the illuminated wrench. With sled off, the gauge doesn't register engine information so the wrench went away. Maybe I just need to try looking at the diognostic page with sled running.
