Cruise control "resume" on V85TT?

[sunGuzzi]

My Cruise Control increment/decrement/resume never worked from day 1, but could set current speed only. First dealer had NFI how to resolve. So I tried every trick in the user manual to rectify/upset it. Wheel re-calibration, speed unit swap over etc...no success. Got some phone advice from interstate dealer who said it required the MG ECU access tool to rectify and that MG Australia had sent an email about it. Useless dealer #1!!!

Finally found a more enthused dealer and they fixed. They said it was to do with the ECU re-learning wheel parameters, so some sort of a bug obviously...and beyond what we the user can do. Could only be done via dealer MG tool.

Has been rock solid since.

For what it is worth (I have no solutions to provide yet), my 2021 V85TT is doing the same thing. Cruise control works, but can't be changed up or down by using the toggle like it did before. Yes, this feature did work before, but since I had the first service done recently at the dealer, I believe they re-flashed the ECU and now it doesn't work. Another odd thing that is happening since the service is that the check engine light rapidly flashes when I reach 5500 RPM every time, and then stays on until I shut the bike off. Upon restart, the check engine light is out, and will stay out until I hit 5500 RPM, and then stay on until the bike is shut down. I have no solutions yet, but suspect it has something to do with the re-flash that was done. I am hoping to get the bike back in very soon for them to check it out and will provide updates.

Sorry for the late update, but I did take the bike back under warranty and the dealer "re-flashed it again," and now the cruise control up/down speed toggle works perfectly just like it should.

Update on my old post. The initial service and ECM flash caused mine and others CC to not increment decrement  properly as you all have seen. They had to set to Miles not KM on a re flash and it works fine now. So we have seen heated grip additions and ECU? ECM flash cause this issue. I see in the posts and have seen on my bike the option to calibrate the throttle so that might fix the heated grip scenario. The KM and Mile thing is a dealer flash. NOTE today the dealer had to push new software as there is a new flash out since a few months ago. He had issues getting the MAP? to push and had tech support on the line over two hours to get it right. I had tried changing my setting to KM for the issue and no difference.
New V85TT on the floor needed new MAP as well so its out for new stuff and my 2021.
Indian of Monmouth was good to me, also has an espresso machine in the Vespa area.
Now if we can get decent looking 1" hiway pegs I am ready to hit the longer rides.
Best to all

I had the heated grips installed today and mentioned this thread to the service manager and asked them to make sure the cruise still worked before giving the bike to me.  They said they never had a problem on any installs,  but did verify it all worked, which of course I checked first thing after I left.

I assume you mean Guzzi official H grips? If so, did he reset the throttle as (supposedly) required by Guzzi? Also, did he upload the new latest and greatest map as yours should be the older one?

Do you recall about when you got the earlier, bad update? Or the update # of what you have now (or the bad one)? I want to be sure my dealer doesn't choose the wrong one.

UPDATE as promised!
Today I went to the dealer for an update.
Apparently the Italians forgot to put some things in the update before.

I noticed severall things after the update I got earlier:
- Bad pickup during warm weather 30°C and up
- Less difference between Sport and Rain mode feeling
- HIGH mileage 3,8L /100km mixed use but it felt like I lost 20 horsepower
- Cruise up/down set/resume not working anymore
- Engine running not smooth
- very unsteady on the gas

Today I got a new update and all those things are solved. It runs even better than before the earlier update now.
It seems that the engine was running realy lean to the point it was not healthy anymore. Also fixed by the update.

I'm happy again

Hate to resurface this topic after a few months gone by, but I learned that my 21 TT does this too. Will not resume/accel/decel. Short of having to visit a dealer for this fix, does anyone know how I could fix this myself? Riding 100 miles to a dealer for this is not my best option right now.

I have a 2020 V85TT and found the CC to be finicky at first.

Starting point read the owners manual on CC operation. In my manual it starts on page 100. The only long hold on the CC button is to enable or disable the CC. As an example once engaged and the speed is set and the clutch or brake is hit the CC is disengaged. Now to resume press up on the button for no more than 0.6 seconds, this will resume. A long hold will not do anything. The same is true for the accelerate and decelerate. A short bump up or down, not a long hold. Just like to set your speed a short central bump will do the trick a long hold will turn the CC off.

The same holds true for the ride modes, short quick bumps on the starter button to change modes.

Yeah I've tried that. Oh well, I can live with it until I make my way to a dealer. It does hold speed just fine though.

Luap, you might try resetting the throttle as Huzo describes in reply #18.

Tips, when you do the reset find a straight flat road and use second or third gear with the cruise. It's very hard to hold the throttle. If you can contact the original owner I bet he did the latest map and the dealer messed up. If so he should fix it free. Ha!
Fyi there is a lot of other changeable studs in the menue.

By chance, did you happen to get the number on this new update you received?

Having the number might be helpful to others with the same problem to identify.

[Luap McKeever]

Yep. Tried that too. Thanks.

[rocker59]

Yep. Tried that too. Thanks.

Luap,

I'll bet you're going to have to ride over to Tulsa and get the latest download from Guzzi.  Maybe Mother Road will give you a Saturday appointment and you could ride over and back same-day?

I had a similar issue on my last V7 Special and did just that.  Scheduled at Saturday appointment, rode over to Tulsa for the download, ate lunch, rode back to NWA.
