I installed the OEM heated grips on my 2016 Hyperstrada 939 as outlined in a previous post; took the bike in for the 600 mile service, and asked the dealer to turn the grips on in the ecu. The tech said the heated grips option did not show up on the Ducati Diagnostic Tool while it was connected to my bike. I checked the wiring etc, and all seems fine. Any thoughts why this may not be showing up or is there a sub-menu that needs to be accessed to turn the heated grips function on?

Thanks,

Aron
 
How old are the grips? Did you buy them new? Could have an open circuit or short... but that would be weird to have on BOTH grips, and my guess is the computer would indicate a problem if it detected a short since its a normally open circuit w/o grips installed. Probably can't check for power FROM the bike unless he was able to activate the function in the computer w/o seeing the grips. Could check for resistance across both leads for each grip.
 
Grips are brand spankin new, purchased from DucDealer. And yes, I wondered why would both not show up, very unlikely they both have an issue, but certainly not uncommon. I'll check resistance, also, not certain about the working voltage, but I'll test them with maybe 4-6 volts from my DC ps to see if they get warm.

My other thought is maybe the bike needs to actually be running for the grips to show up. I know they shut off below the set RPM to save the battery, so that may or may not play a role. I'll start by testing the actual grips and go from there...

Thanks for the ideas.

People are reading between 6 and 9 Ω (ohms) for their grips from what I am seeing. If your multimeter reads "OPEN" or "OL", its an open circuit and there is something wrong internally with the grips. Get a cheap pair of Bike Master grips ($30) if you see problems with the Ducati ones and they are not under warranty. They are a little fatter (like the Oxford and others as well) than the Ducati brand, but that's what I just installed and had activated, and I am super happy with them. Look good too.
 
Right side measured 7.1 ohm, left side 7 ohms, taking away 1 ohm due to wire resistance, and that leaves about 6 ohms, so looks to be good. I also plugged both sides directly to the auxiliary power connector under the dash that is probably designed for a gps (aux); both sides with ignition on started to get warm, so the grips are good. I'll have to ask the tech to start the engine with revs above 2000 to see if it shows up on the diagnostic computer.

I thought about the aftermarket grips which are way more affordable, but I just liked having the starter button as the switch with 3 settings and the cleaner look, as this mod is the most important one for me.

Thank you for the great tips!
 
wait, so grips have to be installed first before dealer activates the grip warmer option in the ECU?
 
Interesting.....now I'm wondering why the option to turn them on wasn't available to the tech.

I don't believe so. I think some members here had them turned on before installation.

I have a HS 939 that I brought the 2nd hand (5000kms). With engine running, pushing the start button showed (from memory) "grip fault"
I had after market grips fitted & connected to Ducati connectors behind head light.
Now with engine running & starter button pushed shows grip settings & they work fantastic.

Sounds like the grips are good at least! And yes, that other plug should be labeled "GPS", and the other two plugs should say "HEATER" or something

Aftermarket works with factory switch no problems, which is awesome. Just use the adaptors that are plugged into the harness and solder it. No modifying the factory harness! Direct plug in

Did you plug them into both heater plugs or did you splice them and only use one plug? (Im assuming not, just have to ask to make sure).

And no, apparently you can't activate the grips without them being installed. The computer needs to see the grips to turn it on according to the tech, and then you can plug and unplug them after that no problems. The tech tried the day before on another one and it wouldnt work until the grips were plugged in.


My guess is it was a user error on the tech side of things (no offense to the tech, it happens). "Try restarting the system and re-attempt" :p

Tell him/her your findings, see if they will brainstorm with you
 
They are both plugged into their own respective sides. I tested them one at a time with the gps plug, both warmed up. I will also ask the tech to start the motor and rev'it up a bit to see if that will help. But yes, these things happen, and they are good people at the dealership, so I'm certain it'll work out.

Thanks for all the input!
 
Plug for heated gloves option: Hotwired Heated Gloves

They heat your whole hand, integrate nicely with heated jacket, and warm enough that I don't even need heat above 45F.

I was on the fence about grips and almost pulled the trigger on the cheap versions. I prefer the thin diameter grips and didn't want bulk. Started looking at heated vests, which I needed more than anything and stumbled across this product line. Top notch.
 
I have some ocd with anything more than just plain leather (preferably deerskin;) gloves, and having a wire connected to me would also drive me wankey, but I guess we all get different mileage....aside from all of this, even my trackbike has heated grips that came stock lol, so I'm used to them.
 
Stopped at the dealer today; in-and-out in less than 10 minutes, and the grips show up on the dash and operate with the starter button. They were busy, so I didn't get a chance to ask what made it work, but the clock and trip counter were reset, so maybe a reset, and it showed up on the diagnostic tool.

Thank you all for your input!
