When it worked it was impressive as long as you didn't touch the foot brake.

The EPS quit once and started working again with no problems since. Hopefully the ADC just took a "brake".

 

And I don’t see why you wouldn't; its soo believable.

 

I'll check the ADC fluid tomorrow. And the muffler bearing too.

 

Were you using any throttle when you were going down the hill?

 

Nope. I was too busy trying to control the thing. LOL

 

I rode around here at the resort a bit today gathering hoses so I could leave the water running down at the caboose village rather than the overflow running in the canyon onto the dirt road.

So I putted around a bit and climbed a few little hills and with the ADC working like the old EBS the rear just slid down the hills. I thought I would go for a real adrenalin rush so I went up a steep hill that is really loose so I could test my skilled riding abilities.

Now the ADC light doesn't come on at all but the ADC was working coming down the really steep hill yet 5 minutes before that it didn’t work at all.

So, now the ADC works intermittently. The ADC light used to come on even when it didn't work but now the ADC light doesn't come on at all.

As soon as I get my Christmas Tree it’s off to the dealer.

 

While riding yesterday the ADC indicator was on when all of the conditions were met for the ADC to work. The ADC still doesn't work but the indicator does. The indicator was not coming on the day before.

I think ADC is a HUGE improvement over what Polaris had in the past. I don’t like that it only works with the throttle completely closed. If you want to go a little faster than a crawl then as soon as you touch the throttle the ADC quits working and your back to the same old scary useless dangerous rear tires locking up and sliding down the hill.

I am not a fan of how the on demand 4-wd works either. I do not like the delay in the front wheel engagement and I really think that when you put something in 4-wd that it should be in 4-wd.

Corning at high speeds and giving it a little throttle the rear end likes to break loose before the front wheels engage to aid in pulling you through the corner. This is not good if you decide to power through a corner. If I wanted the rear to slide around corners I would select 2-wd. Isn’t that why you have a choice?? I want to decide when the front wheels are engaged and disengaged, not the machine.

I do prefer the handling characteristics at high speed of a SRA as to this IRS too. I'm sure the weight comes in to play here too.

There is too much criteria for things to work on this ATV. For the ADC to work (if you’re lucky enough that yours does) you have to be in 4-wd, be under 15 mph, have ADC selected and the throttle completely closed.

Did you know that if you are riding along in 2-wd at let say 25 mph and select “on demand 4-wd” that the 4-wd will NOT engage until the engine RPMs have dropped below 3100 rpm?? What’s up with that?? Where’s “On Demand”??

For me today I prefer the 4-wd that Can Am uses. I like the viscous coupler in the front diff because it is not regulated by being in high or low range and is not tied to any kind of a rev or speed limiter. Its aggressive and and its always there, even at wide open throttle. And you decide when the ATV is or is not in 4-wd.

 

If you're in High gear you should be able to shift on the fly into AWD. I think you might have an electrical problem between what is happening with the ADC and the AWD not engaging quickly. It should be much faster than Can-Ams you've been on. At least on my Polaris it's almost impossible to see how fast it engages. With the Can-Am it's more gradual to engage. I haven't been on any Can-Ams 2011 or newer though. Done plenty of high speed AWD in the snow, ice, and not so deep mudholes. Haven't experienced what you are going through. I haven't been on an XP so I don't know if they changed things around a bit.

 

Its headed back to the dealer pretty soon.

I like as many things about it as things I don't like.

 

If you can detect when the front end engages, then you must have a problem with the atv. I have never been able to tell when mine locks in or unlocks. It only takes about 1/6 of a turn on the rears before the front locks in. Can Am can have there Crisco lock diffs. I have seen plenty of those in action (or inaction) to know I prefer the Polaris set up.
I agree there have been a few times when it would be nice to lock in the front end regardless of what is happening out back, but there is just no perfect atv out there. If there was, no one would be able to afford to buy it.
