P0562:
MODULE: DPS
DESCRIPTION: System Voltage low
CAUSE: Blown fuse, battery low (damaged magneto/regulator), damaged circuit wires or connection, intense winch usage
ACTION: Check the two DPS fuses Validate that all the DPS connectors are secured Measure voltage between harness connector DPS2-A&B and ground (expected value – 11 to 13 volts) Measure batter voltage with engine stopped. (Expected value 11 to 13 volts) Check ground and positive connections on battery.

P1F05
MODULE: DPS
DESCRIPTION: Motor current sensor range/performance
CAUSE: Motor input vs output Current correlation check failed
ACTION: External troubleshooting is not possible Replace the DPS

A P0562 code in a Can-Am ATV indicates that the Power Control Module (PCM) has detected a drop in the vehicle's voltage supply:

• What it means
  A P0562 code indicates that the voltage supply in the vehicle has dropped below a certain threshold. This can cause electrical components to stop working or stop working altogether.

P1F05

Module: DPS

Description: Motor current sensor range/performance

Possible Causes: Possible internal component failure

Service Actions:
If Occured: - Check the connectors on the DPS for moisture and corrosion. - Clear the Fault.
If Active: - Key-Off until complete vehicle shut-down. -Key-On- If fault is still active, further external troubleshooting is not possible. DPS must be replaced.


That's from a BRP Spyder forum, but it's probably similar.

The P0562 and low voltage associated with it could have caused the P1F05 code easily. When my fuel pump fuse blew I got like 4 codes that had nothing to do with it.

I would replace the battery, worst case scenario is you have a new battery. Then you need to get those codes cleared and see if it stays away.

After that I would focus on corroded connections or possible mice damage or loose wires. Your voltage while running looks good so I doubt it's a charging system issue.

If you had the DPS code by itself I would say yeah maybe the DPS module is bad, but with the voltage code I doubt it's the DPS module. That's just me.

The only other thing I will say, is that if everything else is good, and the DPS module is going bad, it could be dragging the voltage down itself. Like sometimes when a starter goes bad it pulls wayyy too much current. Almost always the low voltage causes the DPS to bug out, but it's possible it's the other way around.

@Chief... and @10mm_
Thank you both for detailed code explanations.

I would replace the battery, worst case scenario is you have a new battery.

Then I will try this first. I will keep you all posted once I have obtained and fitted a new battery (may take a little while).

I had my DPS cutting out on me, last week. Turned out one of my battery terminal connections is stripped and had loosened a bit.

 

[cptmorgan]

Update: I have now tested with a new battery, but unfortunately the error persists. - My battery guy didn't have a new battery with the right terminals in stock, so he let me borrow another one so that I could test with jumper cables. But nope.

I also disconnected the cable connector that goes into the DPS unit to check for corrosion, but it looked fine. Unfortunately I was about to say.

Grease had been used also here (as was also the case in rear fuse box).

By the way, if anyone else here should ever need to disconnect this connector, the trick is to first pull out the white bracket (which function is to keep the connector locked in place). Perhaps common knowledge for most on here, but I for one had never seen this variant before.

To sum up, I don't think there is any way out of delivering the machine to a dealer for troubleshooting and repair.
I will update this thread when I have more information, but it may take some time (weeks) before I can get it transported to a workshop (which is quite a distance away).
Have a great weekend all, and many thanks to all who has contributed with possible fixes.

 

[CanAmRancher1]

Yep. Was just going to say at this point, you need to have codes reset so you can see for sure what code is popping up. Thabks for keeping us updated.

 

[DaveB]

I see you tested battery voltage, but did you load test it? Big difference. If your battery has a bad cell in it, it may only show up under load. See if you can borrow a known good battery (the correct one) and swap it in.

I see you tested battery voltage, but did you load test it?

Thanks for your input. Yes, I also had the battery load tested. My battery guy said the same as you; a digital test is only so good, to make absolutely sure a load test is also required. The results from both tests were very good, the same as you would expect from a brand new battery.

It's really unfortunate the only way you could try the new battery was with jumper cables. It's really best to have a good connection at the terminals

It's really unfortunate the only way you could try the new battery was with jumper cables.

The battery came out as top notch in all tests, but just to make absolutely sure beyond doubt, I also tested with a brand new battery hooked up with jumper cables. Sure, had my battery shop had a battery that fitted in stock, I would've gone for that, but I'm afraid the result would've been the same.
Although I have learned from you guys on here that the battery may often be to blame with DPS errors, I believe we have established that in this case here, a DPS failure unfortunately is just that, a DPS failure.
But thanks again for your input. I'll keep you all posted when I have the final answer.

We will be waiting, good luck.

I disagree.

You haven't tested the machine with a new battery properly fitted. And you haven't cleared the codes after doing so. Those should be the first two steps. Hopefully your shop does that instead of throwing parts at it.

 

[cptmorgan]

You haven't tested the machine with a new battery properly fitted.

That's true, but I have tested with a new battery hooked up with jumper cables.

And you haven't cleared the codes after doing so.

Surely, the error codes can hardly be deleted as long as the error persists?
Also, doesn't one need more sophisticated equipment to do this, or is it something you can do yourself?

 

[cptmorgan]

The vehicle will be taken to a dealer later this week for further troubleshooting and repair.
I have recently changed the engine oil and filter, and also lubricated all the grease nipples, so this is already in order.
I have agreed with the workshop that they adjust the valves and change the transmission oil as well as check the brakes while at the workshop. - Are there other service points that it might be a good idea that the workshop to look at at the same time?
Thanks.

Have them inspect the belt and clutches and clean the dust out.

I don't believe dielectric grease is a conductor. It's meant to seal out moisture. If the sockets and blades are all slathered in this grease, there could be intermittent electrical conduction failures.

It's not a conductor but it would not cause connection issues in the amounts pictured.

 

[Tozguy]

Dielectric grease should not cause connection failures but it would not fix a bad connection either.

 

[cptmorgan]

I have finally got the ATV home from the workshop. The DPS unit had to be replaced, as suspected. Fortunately, it was accepted under the right of complaint.

Have them inspect the belt and clutches and clean the dust out.

I mentioned this to the mechanic, but he didn't see the need for this on a vehicle this new and with so few hours. However, I had the them adjust the valves and check the brakes as well as change the gear oil and spark plugs. (I recently had it greased and changed engine oil and filter so that was already OK).

Anyway, thanks to everyone who contributed to the thread.
