Well, I've had my 2015 midsize 570 Crew EPS for just under 2 months (currently have 34.3 hours on it) and today I had my first dash light come on. We had just finished a 10 mile ride in the snow and got back home. I stopped, put it in reverse and backed up, then pull into the garage and as soon as I rolled about 10' forward, I had two lights come on. Turns out one is the EPS Warning light and the other was the Check Engine light. The manual says of the EPS warning lite that if it remains on the EPS system is imperative and to see you authorized Polaris dealer. The Check engine light says the indicator appears if an EFI-related fault occurs. Do not operate the vehicle if this warning appears. Serious engine damage could result. See your dealer.
So, this 10 mile trip in the snow was in Low range the whole time and we never got over 15MPH. We did go through a couple of deep snow drifts when we first started out, but the last 8 miles was just snow packed county roads. None of the lights ever came on until we got home. Anybody got any ideas? We are expecting snow again tonight and I will need to plow in the morning. Thanks much.

Don't know about the Efi light but on my 2015 Xp 900 when my Epson light came on it was due to a low battery could be the same for both Not sure but there are a lot of more knowledgeable people here than me

Thanks for the reply. I did get the codes for both problems. I got the following codes with the first number in the left corner of the display, the second number in the right side of the display and the third number in the lower right of the display:

Error code SPN FMI
0 84 2
1 84 19
2 190 2

Can anybody tell me what these mean?

From what I've read on this forum, there seems to be an ongoing speed sensor issue. Most say to run the machine at 4000rpms for about a half a minute and it will clear but these were all with 900's. Does anyone know if it's the same problem on the 570's and where the speed sensor is on the 570 and would it be an issue of icing up that caused the problem or is it just symptomatic for Polaris?

I've had the check engine light come on a few times. Every single time it was something that got wet. I let it sit for a day or two to dry out and all was well again. Might be your issue with all the snow you went through

 

[Mtjag]

Littlebigrancher, thanks for that response. I've got snow caked all up under the machine, around the shafts and up behind the engine (from backing into a snow bank). The first part of our ride was over an unplowed road and I was pushing snow with the bottom of the skid plate. Definitely got the AWD workout on that part of the run. The remainder was just snow packed road and I drove slow for my wife. I've got it parked in our heated garage so it will dry out good tonight and we'll see what happens in the morning when it's plow time. Thanks!

Might wanna try and unplug some plugs and see if there's moisture in them. If so I would highly recommend using dielectric grease on your plugs

If it's running normally, and all your fluids are good, I'd give it some time before I went running to a dealer. do you have a space heater and a shop/shed that you could use to get the snow melted out from under the thing to see if it improves?

If it is a speed sensor issue, usually you'll notice the speedometer stop working for a bit (mine does this when going through snow or when caked up with ice, but it's a fullsize) and it will trip the check engine light...

My 570 ACE has done the 0 84 2 which is a speed sensor. If you have EPS it gives a code for that too I think.

I just ran it around for a few minutes and it went away.

 

[Mtjag]

Well, I decided to take it back out for a spin before dark here to see if running it over 4000 rpms for a few minutes might help. After just about 30 seconds, the check engine light went out, but the EPS light remains lit. So, I'm going to leave it for the night in the heated garage and tomorrow will unplug the wires to the EPS unit to see if there is moisture in there. Thanks for the help!

 

[littlebigrancher]

Good deal. You half way there lol

 

[papa10]

If I am deciphering the service manual correctly, both of the "84" codes are speed sensor related. The "190" code says: "Engine speed(this is applicable when the EPS module gets the engine speed from the ECM)". Manual does not show a 190-2 code. The above code explanation is for 190-31(error in engine speed computation) and 190-19(received engine speed has error). Hope I didn't thoroughly confuse you.

UPDATE: Well, this morning I went to the garage and the Ranger kicked right off with no lights on. Everything seems to be reset and running fine. I guess the speed sensor just got plugged with snow and that set off EPS and Check Engine light. As several have stated on this forum, you just need to run it at over 4000 rpms for about 30-45 seconds and when the Check Engine light goes off, then you reset the EPS light by turning the machine off and restarting. Of course, making sure the the speed sensor is not coated in ice is probably the first thing that needs to happen. Anyway, just wanted to say thanks for everyone for their input. This is a great forum is the lagniappe of Polaris. In Louisiana, where I am from originally, lagniappe means "a gift or a little something extra" and that is what the helpful members of this forum represent.

One piece of advice, go get dielectric grease and start filling connections up so it don't happen again

I am in ND so snow is going to be a big part of what I drive in. What do I need to do to snow proof my machine???

 

[littlebigrancher]

I have no snow experience but any electrical connection that could get moisture in it I'd put dielectric grease in it before you have a malfunction.

Got some and will do...just be lazy today, but that is on my short to do list. Thanks for the reminder!

 

[Mtjag]

Ok, I can't determine which is the speed sensor so I'm just going to put dielectric grease on every connection I can find. Like NDranger, I'm in snow all the time up here so I need to get it as water proof as possible.

.......so I'm just going to put dielectric grease on every connection I can find......

No harm in that.
