Rebuild a DPS

[Kennard]

Was looking at another Spyder site and asked about DPS unit failure, was schooled on post of DPS do not fail or not mentionable enough. All I was looking for was are the units rebuildable. With the failure rate since release someone a lot wiser than me has cracked one open. I have one I replaced last spring but wouldn’t know what to look for. At $1800.00 a unit I’d bet someone would come up with a business to rebuild them. Thanks all just curious.

Tough one....

Do not know of anyone who has ventured into that device. Parts are not offered nor diagrams or specs for one to work on them. From all that have failed I have never heard what failed. Electric motor, sensors, computers control etc. Some just live without many shop around for price or search salvage yard service sites. I would suspect if someone did try nd found a way it would be expensive and not enough to make it worthwhile. :thumbup:

:agree: ……….. in todays world normal car engines are not re-built by DIY'ers any longer …. it's easier and less expensive to just by one that someone else has re-built ( ie remanufactured ) …………. jmho ….. Mike hyea:

Thanks for your reply, I’ll keep mine to remind me to keep battery charged and terminals clean and someday I’ll make a boat anchor out of it. In closing did it come off the space shuttle?

I have wondered also why these are not repaired. At a guess dealers are not going to rebuild one since they would have no manuals or parts and liability would be high.

If I had the need, as in if ours failed, I certainly would repair it unless impossible to do.

If you are local or inteseted in shipping it to me, I can give it a look and if repairable, you will have a spare.

A Spyder Ryder here in Aust has looked into rebuilding these DPS units, try dropping him a pm, he's here on the Forum, goes under the username of Stu.

What is a "DPS"?

 

[ARtraveler]

Just another one of those overly high priced disposable parts. Ain't technology great? :roflblack:

I would tear into my failed DPS unit in a heartbeat. I spent 15 years rewinding and rebuilding electric motors, gear drives, electromagnetic devices, and even rebuilt motorcycle stators and automobile alternators. I may not be able to repair my DPS and end up buying a new one, but I'll sure as shooting give it a try. What is there to lose in trying?

What is a "DPS"?

The power steering unit

The power steering unit

Dynamic Power Steering to be exact. I assume that the 'Dynamic' refers to the variable amount of assistance this unit is designed to deliver. More assistance at low speed tapering off to zero assistance at higher speeds. So if this unit fails, you will not notice any difference over the cut-off speed, which I think is around 45 mph but don't quote me on that one.

I have not heard of anyone fixing one. I have never had one fail so have never had any reason to take one apart. From the few that have reported what the fault code was that required the replacement of the DPS. It seems to be mostly a torque sensor type failure and mostly an open circuit on the torque sensor in particular. That sounds like something that could be fixed??? Would you happen to know the specific fault your DPS had before it was replaced?

For those of you that do not know. The torque sensor is internal to the DPS. It measures the amount of torque applied to the handlebars by the driver. It does that by measuring changes in the magnetic field in the input shaft as torque is applied.

I've had 2 go out on my 2008 GS. First one was DOA. Took me awhile to figure this out (actually Lamont figured it out), because it never worked and I had nothing to compare it to. They took a DPS unit off a brand new Spyder on the sales room floor to get me back on the road. Same faulty design and it didn't last either. My 3rd DPS was an upgraded model and it's still working. But I agree that it may well be that at least some of these DPS units could be fixed if someone knew what they were doing.

Interesting story behind the early DPS units. Seems that BRP did a lot of testing of these units with thousands of simulated hours of use. They were placed on a machine that turned them lock to lock under load, continuously for weeks on end with zero issues. But, how often do you actually turn your handlebars lock to lock? Not very often. Turned out that lubrication at the bottom of the DPS was only delivered to components higher up in the mechanism when turned all the way to the left or right. So with normal use, these components did not receive adequate lubrication and failed. This engineering flaw was corrected in later models so this is no longer an issue.

Good point. I forgot about some of the early ones failing without throwing a fault. That would rule out the torque sensor issue on those units being the problem.

Seems to be what is happening with my wife's 2010 RT SE5. I rode to work yesterday about 40 miles into the trip I go into "limp home mode" and "Check DPS" but when I hold the mode and set button with the blinker, I do no see a code. So I pulled over and shut it down turned off the key and waiting about 10 seconds. Started back up and ran fine for the next 20 miles. Then after work, after about 40 miles again the exact same thing happens. Shutting it down for 30 sec or so seems to clear the issue.

 

[billybovine]

By your description there is a fault code. It just may not be active at the exact time that you do the 3 button push. That is because you can only retrieve fault codes that are active. Codes that have occurred can only be retrieved using BUDS. When the early DPS units failed without throwing a code. There was no limp mode or warning on the gauge cluster. The DPS just stopped working. So if there was a warning on the screen.

Both times my DPS failed, I got no code or limp mode issues. However, it started steering my Spdyer for me on the 2nd failure. That was interesting. It was all I could do to keep my Spyder going straight at times. Luckily, it was intermittent. That steering motor is very strong. I think it will throw a code if the motor draws too much amperage. Though I think it draws quite a bit even when it is working correctly.

Hope you get it worked out.

would anyone be interested in joing a class action suit againest BRP on these DPS failures, 12000 to 2000 dollars a shot on a problem that has been around for years

Update to took my volt meter to it and with all accessories running and at 3500RPM I am sitting at 14.2-3v with nothing on it's steady 14.4v at 3500RPM and at idle about 14.2-3v all of these numbers to me indicate a good charging system and healthy battery. Just so weird, it seems to happy right about 40 miles like clock work. The longer I own this thing the more i want to sell it. It pisses me off when manufacturers try to basically lock you out of working on it without $600-1000 scan tools. They are strong arming you into taking it to their dealer.....

After sitting for a few hours battery is at 12.5v with Key off. With key on voltage drops to 11.99, 97 97, 96 counts down fairly quick. Think i'm gonna throw a battery at it first.

 

[Grizzly]

Replaced the battery and so far 150 miles with no DPS warnings.
