Got the exact issues you described. Brought it to the shop and got the dps updated with no effect. One of the mechanics thought it was related to the speed sensor? If they figure it out I'll post the results.So did you check any of the wires that were talked about earlier in this thread?I put this in another topic than I saw this one.
Started having DPS problems last summer. While idling and stopped it would go out and give check DPS along with engine light. I have tried to replicate it while at home by running water on the connections but could not. (Seems very random.) Than I start it up in my garage and it does it. Turn it off let the system power done and it resets. Bought it in to dealership and they said it was showing lost communications with DPS, reset and gave it back saying they don't know why and BRP would only pay for a replacement if it was throwing a certain code, which of course it was not. Needless to say not very happy. I than started troubleshooting, took all electrical connections cleaned and reattached hoping it was a bad connection. Rode bike all day yesterday and no problem, just about the time I think it was an electrical connection issue it does it again. Same thing stopped and idling after riding in water it goes out, stop it let it power down and reset. as soon as i restart it does it again. Next time when I start it I put the key in lights on and it stays working. Ride it for awhile longer stop let it idle for a long time no more trouble. I know from my troubleshooting that if you disconnect the communications connection on steering motor, it will go out and give code but as soon as you reconnect it starts working again, But if you disconnect the power connection it throws code and won't reset till you ether stop and let it power down or disconnect and reconnect communications connection. I am starting to think it may be a low voltage issue, having lights on causes it to put out more juice, but am at a loss as to what to try next. By the way it is a 2011 Outlander 800 XT.
