Hi. I promised I searched the forum for this answer first, so if I missed it, please don’t bite my head off!

As I’ve posted, I’m building a race bike out of a salvage bike I purchased. On my first ride, I realized the quick shifter wasn’t working. I read through some threads and heard that these go bad easily with water or break easily. So I assumed it was bad mechanically.

As I read through the manual, I saw that you can go into the settings and make adjustments on the quick shifter. I tried to go in and see if I could turn it on, but it does not come up as an option. And I don’t see the icon on the dashboard. So I’m assuming it’s a software thing? Or maybe because it’s broken it’s not being registered by the system?

Or is there some type of dealer add-on I have to pay for? I searched, and it seems like the Panigale V2 comes with auto blip/quick shifter without having to pay extra to “turn it on.”

Any insight would be appreciated. I will likely upgrade into an aftermarket, quick shifter anyway, but this would be good to know.

JB

It isn't a pay to play type feature. The bike has it from the factory, and it should work. On the early V4 models, it showed up on the lower right side of the dash and could be configured there, IIRC. On later versions of the V4, and I'd presume the V2 as well, you can only turn it off and on in the settings menu in the left dash menu.

By the looks of the bolt head, someone has been at that shifter. All of the +5V shifters on the market function the same. The bike supplies +5V to to shifter, which also has a ground wire. There is a signal wire, and on the V4 - I presume the V2 as well - goes straight to the ECU. At idle the signal wire sends maybe 1.8V. For an upshift, maybe 2.4V and a downshift 0.8V. I'm grasping for these values, I just can't remember, but it's something similar.

The other piece to the puzzle is that the bike will ignore the QS signal if certain conditions exist or are not met. So if there is a trouble code with another part, an error from a wheel speed sensor etc.

I'd trace the wiring and make sure everything is plugged in and I would resolve any other check engine or trouble indicators. Test the voltage if you have the means. See that the supply to the QS is +5V, and the idle, up and down shift values are changing. If they are, something else is stopping the ECU from triggering the shift.

Is the bike stock otherwise?
 
Do you have TEXA or OBDStar? Maybe try resetting it? Don’t you have to do something similar if you change the gear position sensor?

Wow, super helpful. Thanks.

Good call on it looking like someone has messed with it. Maybe it’s a replacement.

Yes, I got to the settings today and was not able to select a quick shifter setting. It’s like it doesn’t think it’s there. The little gap between EBC and DTC, on the right side of the dash, should have “QS,” or something similar. So since it’s not software/permission issue, it’s gotta be either that the QS is bad, and not sending a signal to the ECU, or as you say, some other interference in the system (or both?!).

No, I’m not seeing any other codes. I don’t think. It’s also new to me. Nothing stands out as a check engine light, but let me get in the manual and double check.

Yes, stock.

Testing the voltage to the supply I think it’s the next step. Yes, I can do that.

Honestly, I don’t even know what those are, ha ha. I’m assuming some type of third-party diagnostic tool/software?
 
The Ducati (dealer) diagnostic system (DDS) is a branded version of a Texa Navigator. These are diagnostic devices. Modern vehicles have a CAN bus (controller area network) which is more akin to a computer network than typical old school vehicle wiring. If you have a device which can read Ducati's CAN bus, you can see in real time, sensor output values in addition to many other benefits.

OBDstar is the Chinese knockoff of same. I have one and it's been pretty useful. It's an OBDstar iScan Ducati, in OBDstar's naming.

What year bike?

What are the two exposed wires in your pic? Mirror turn signal?

He’s a screenshot of the manual. You can see where it has “Q/S” where my dash shows a blank. Again, I’m also not able to access a QS feature in the settings. So it would seem to me that the ECU just isn’t picking up that it’s there. Maybe it’s just not plugged into the ECU. Or maybe it’s broken and not setting the signal.

I’ll do some tests tomorrow.

The manuals don't get updated as much as the bikes. I wouldn't bet too heavily on that. Check and verify everything is plugged in and getting & sending the correct voltages, but its not something that has to be activated.

Thanks again for that.

OK, I think I need to get one of these diagnostic tools.

It’s a 2021. Yes, that wire is just from where the mirrors were broken off. I couldn’t imagine that’s affecting this issue?

But this bike was a salvage, and the guy obviously did some stuff putting it back together. So who knows what he did wrong, or forgot to do, or left unhooked. I did a basic safety inspection and took the body off a little bit and cleaned everything up to make sure it was safe to ride. But I didn’t go super deep. I was going to do that this weekend at the mechanic shop. I put a few hundred miles on it already and it rides pretty good.

OK, will do.

Here’s a semi related question: if one gets an aftermarket quick shifter, does it register in the settings like the OEM one does and allow to be adapted based on riding mode etc.? I.e., Is it truly plug-and-play?
 
If you are on a 2021 your bike is fully supported with OBDstar by now. They're typically a year behind Texa who, I'm sure by contract, is a year behind Ducati.

Depends on the QS. Cordona is plug and play, at least on the V4. But, it is a strain gauge type and not a switch like OEM. I'd look to one, (H&M?) that allows you to adjust it and is a strain gauge type.

Got you. Yeah I was going to do Translogic. I know I would need it software interface to adjust it, etc. I’m just wondering if it shows up in the Ducati dashboard settings.
 
There's no adjustment of the OEM or shifters which don't have some sort of logic board and switches in their wiring. Again, this is all based on the voltage they send to the ECU. Maybe if you can write the ECU and change values (cut time or blip) but that's far and beyond what you have going. You need to get a functional shifter first.
 
And just another note: the bike was crashed on the left side, and the gearshift it was broken off. Which is why I am suspect of it being a broken internal on the quick shifter, which is what I thought before I thought it was a software issue. I should’ve mentioned that before, ha ha. I assumed it was just broken and had another one ordered but then poking around in settings, I thought maybe it was a software issue and wanted to investigate that first.

But testing voltage, and running down wires, is obviously the thing that needs to be done first before replacing parts.

I get all of that. I’m just wondering that if I were to get this aftermarket quick shifter and plug it in, instead of testing, would it “show up.” Just a thought. I’m still going to do the testing.
 
I doubt it, unless there was some type of fault with what you have now, and even then I wouldn't bet $400 or whatever it is for an aftermarket QS.
 
If there was a problem w the quickshifter or it was disconnected, I would think it would display an error on the dash

If DQS is in degraded operation mode, relevant indication is displayed flashing.
If DQS system is disabled, "Off” is displayed. When in fault, the red "Err" message is displayed instead of the level.

Is the current quickshifter the original or replacement? And did you buy the replacement new?

Also, I’d check to see if aftermarket would cause any problems before pulling the trigger.

I’m not really explaining it well.

there’s no error in the dash. And no “off.” It’s just like it doesn’t think it’s there. Like I was saying earlier in the post, if you look at the picture of the – it’s a blank spot.

It’s an OEM quick shifter. I don’t know if it’s a replacement or what. I just don’t know the whole story of this bike.

I did notice, however, that both the ABS and the traction control amber lights flash when the bike is starting up and I duking right now. The manual states that this means “self diagnostic mode or degraded.” Stupidly, I don’t remember if it’s been doing this the whole time or not. I don’t think it has. I think when the bike gets moving, it goes away. But I’ll have to troubleshoot that again.
