OEM Quick Shifter — Is “activation” Required?

Ducati Forum

Help Support Ducati Forum:

I’m trying to test voltage to the lead going to the quick shifter, but I’m not sure if I’m doing it right. It’s just the right setting on the volt meter? And which two wire Terminal should I be touching? Black and brown? I tried every combination and I’m getting zero voltage reading.

Sorry for the dumb question on the voltmeter. I figured it out.

So the lead coming from the battery/ ECU to the quickshifter is indeed at 5 V. So I think the Diagnosis is a bad quick shifter.

Note: ABS and traction control amber lights definitely DO go off when the bike is moving. So it must just be some idle thing with reset an adaptation or something. So that’s good.
 
I think you should see voltage change on the output lead if you apply pressure on shifter. Someone correct me please if that's not correct.

I’m pretty sure that’s right and was said before, so that’s good.

Is that because the gear position indicator is sending a signal to the ECU?
 
No, its because the quick shifter is sending a signal to the ECU. The three wires for the QS is ground, +5V supply and signal to ECU which will have a certain voltage depending if it’s at idle, upshifting or downshifting.

Got ya.

Well, I tried checking voltage coming out of the quickshifter and had zero. I tried to shift gears and see if it changed, but I just don't have a good set up to do it right. The connector is so small that the voltmeter pins barely fit in the wire endings, and it's hard to hold in place. So though I got zero, I'd say it's inconclusive.

Since this will be a race bike, I think I'd be ending up with an aftermarket QS, anyway. So I think the path forward is to get one and make it work.

With the diagnostic tool you can see the voltage which is being received by the ECU, so you don't have to check it with a multimeter. You can try stripping a wire and taking a strand, placing it in the female side of the plug on the wire you want to check, and fold it around the plug so it extends outside of it and check it with the meter after it's plugged in.

That's helpful. Thanks. I was hoping not to have to buy one, as the list of things I need to pay to replace or fix keeps growing, but maybe it's worth it.
 
Got the Translogic and plugged it in. It did not show on the dash and was not able to be selected in the settings. So it didn't fix the problem, and it isn't a hardware problem.

I've heard stories on new European bikes being left with a dead battery for extended periods of time, and the internal battery, that saves the settings, even when a the main battery is disconnected, can go dead and some of the programming and settings are lost. I'm thinking that's probably what happened here, and I need to bring it to Ducati to have them reset it. Which sucks. My Woolich system arrives next week, and I'm hoping that maybe that's something that it can pick up and/or reset, but I'm not optimistic.

At least I now have a back-up quickshifter...

Did you pick up a OBDstar? Or just go to an independent service center. No need for the dealer to reset it

No, I haven't. But I will now. I assumed that was something Ducati had to do. But aren't there things that only Ducati can do, or can everything that they can do also be done with OBDStar?
 
If your year and model is supported you can do everything the dealer can except for software updates. I used mine a few months ago to reset my PIN code. You can see all of the sensor values in real time and even log them. Very useful for diagnostics.

I guess I won't know if my model is supported until I get it. I guess I could ask them now, but I already ordered it. It just said, "Ducati."
