Out riding yesterday and I see an error code come up Lo10.8, last digit changes from .6 up to .9. I notice my engine temperature climbing so I stop and don’t here the fan running. Turned the engine off and let in cool down, maximum temperature it reached was 210°F, it’s never been over 204°F before. When I turned the key to the on position you could hear the fan trying to come on, running about half speed, cycling off and on several times.

We had been driving at slower speeds in LOW AWD. The decision was made to turn around and ride back to the trailer keeping an eye on the engine temperature and stopping if it looked like it was going to overheat. I put it in HIGH 2WD and kept the speed up to move more air across the radiator. This worked find and we got it back to the trailer with no problems. The code reappeared several times on the way back but the temperature never got over 190°F and the RZR was running fine.

So this Thanksgiving I’m grateful that 1) I didn’t overheat (destroy) my engine, 2) I didn’t have to get towed back to the trailer and 3) it didn’t ruin the rest of the day for everyone else. We put it on the trailer and I rode with my wife in her RZR the rest of the day.

So, this code (Lo10.8) and the fan not running? Is that a low voltage code? Is it possible at 4,500 miles my voltage regulator is shot? Maybe a fan relay? Maybe the fan itself is gone? Temperature indicator seems to be working correctly. Sure don’t want to take it in to Ride Never for repair, so any help I can get here on the forum would be great.

The machine is a 2012 XP900, approx. 4,500 miles, all stock no engine performance upgrades, no previous issues.

Thanks for any help in advance,

Todd
