Normally I would have recommended a Norwegian reset - disconnect the battery, but with the sensitive systems, I do not recommend even that.

 

Is the motormanagement fault indicator on ? In case of an error, the system will default to "N" failsafe mode.....
In that case, sometimes starting 4 or 5 times will reset the error light.

 

The engine management light is not on and the car appears to drive fine in all other ways. Have started it and drove it a number of times since it first stopped working and it’s not reset so I’ve now booked it in with the dealer to be looked at along with another couple of niggles.

 

Hi KirbyBirdie,

Did it get resolved? If so, do you know what the issue was?
I have the same issue with my Stelvio. DNA selector not lighting up and doesn't work. Otherwise no issues.

 

if this is Giulia/Stelvio with new type of DNA selector (monostable), then note they are all the time powered (even car is shut down), I know that people had issues with some DNA selectors of that type (maybe earlier firmwares), and enough should be to disconnect battery for a few seconds to restart firmware. OF course better longterm could be to go to dealer and ask to replace it (if DNA hang is the reason - hopefully newer types are free of issue).

Of course in any case of various car issues, DNA may stop working (Even after battery disconnection it is required to start a car a few times).

I have never dared to disconnect the battery to to a restart of the system. Can that be done without too much disturbance to the systems and other lamps starting to blink?

 

you didn't answered kind of question I embedded in first paragraph - do you have DNA with monostable DNA knob (so the one which returns to mid position on spring, does not have permanently painted DNAR letters, production say >mid 2018)?

disconnecting battery is not any issue - in my Giulia its been disconnected hundreds of times (car is used for development of accessories, and often to try retrofits or learn on how to disassebly some things, do photo documentaiton etc). you only disconnect negative terminal (it has lock button), after connecting it back start engine (there will be ton of warnings displayed, DNA in N mode forced etc), rotate steering wheel max left, max right, centre, let engine running for say 1 minute (engine operation may not be smooth, no worries - it sets its parameters), stop engine, then a few more times turn ignition on/off for couple of seconds, all will be good, no more warnings on IPC.

note that all CAN modules are permanently powered, they only go to kind of low activity when you turn ignition off/close car. Imagine MS Windows without reboot for months or your phone - they will work slowly, cause issues etc. I wouldl say it is healthy to reboot your car every a few weeks, to get clean start - nowadays all is software, and (my experience), software nowadays is totally overcomplicated (and full of bugs - companies use 3rd party libraries for everything and complication level causes that full testing is very hard to do) and put into nearly all units (even mirror adjust knobs or windows up/down button sets).

I did not quite understand the question, that's why I didn't reply. Now with those details I can answer. It is monostable DNA knob that returns to the middle. The letters are not painted, but illuminated (usually at least, mine are currently not illuminated). It is a 2019 model I have, although build in Dec 2018.

disconnecting battery is not any issue [snip]

Thanks!

 

shorterm you can disconnect battery, but at least record with your phone the issue and send to dealer link to video. if that repeats visit dealer, ask if they have updates for your car(maybe there is firmware update for DSCM module - which is that new DNA knob (CAN knob, older type of knobs (not compatible) were electro-mechanical analog signal simple device fully hassle free). I know a few cases in Poland, dealers replaced knobs, and as far nobody of these guys complained for re-occurence. up to you, depends if you want that sorted out quickly but not necessarily long term, or maybe prefer now wait for dealer to see issue and replace knob (hoping that it is better and issue won't reoccur).

 

Thanks. Sounds like the long term fix is the better and since it is not critical, I can wait until he has time in the garage. Everything else is working without issues and it's running in N, which I use most the time anyways.

 

So was at the mechanic. He used an hour without being able to fix the knob. He has now ordered a new knob instead which I can get installed next week. Hopefully will take care of it.

 

Update: the DNA selector was replaced by the dealership back in February 2019. Car has been fine since. Have driven it a few times each week during UK lockdown, but the car was dead on Sunday so had to call breakdown. Jump-pack started it and left it running for approx 90mins then took it for a spin. DNA selector not working again and by today (Next morning) the the battery was dead again. It’s back at the dealership this afternoon. They’ve said they're had another Q4 in with similar issues; dead battery/faulty DNA selector.

 

Update [snip]

Thanks for the update, Kirbybirdie, and sorry to hear you still have issues. I will have my DNA selector replaced next week. Hope I don't get into battery issues after that. Did you have battery issues prior to having the DNA selector replaced the first time?

 

Yet another thread involving difficult to resolve electrical issues. If these issues become known to the motoring press it won't make any difference how well the cars drive, this is all they will focus on.

 

Have had no other issues with the battery or car (other than I seem to have a knack of picking up punctures ).that said though the car is fantastic and a joy to drive.

 

Just had same issue appear on my 2019 Stelvio 2.0. Pulled fuse #21 in luggage compartment for 10 secs, re-inserted and everything works as normal. Fuse was not blown or damaged in any way.

Fuse 21 also supports USB, power sockets and AUX, so I suspect usage of USB chargers (tablets, phones etc) and that the USB charges tend to work their way out of the socket in the luggage compartment on a long drive (causing wobbly connection) which maybe in turn causes the i-Drive / DNA circuitry to hang?

Anyhoo, pulled fuse 21 and we're good.
Happy days.

 

THANK YOU! I had the same issue with my MY19 Stelvio 2.0 and removing the fuse #21 worked perfectly. Saved me a trip to the dealer.

 

Just tried this on my 2020 stelvio , worked a treat , don’t know how long it will last , but great .cheers zdm100

 

My giulia has just done the same. Is it fuse 21 for me too?

 

Bit late but I can confirm this worked on my 2018 Giulia too! Thanks so much.

 

Found fuse 21. Tried it. Success!

 

older firmwares of monostable DNA selectors did hanged up. there is an update for this in dealership, current firmware revision is 4.5, though 4.3 was claimed in some service news documents as solving the issue. most cars with the issue were version 3.7. I think they do it normally when they see specific DTC codes in ECUs (service news list them), though as most of dealers, they do not know such service news exist and may be reluctant to do any updates (as e.g. it is not recall/mandatory update). Some prefer replace selector, what is IMHO wrong approach (wasting good selector which can be just upgraded in 1 minute, and risking your panels scratching or other bad reassembling).

Shorterm solution, and easiest coudl be fuse out, but IMHO easier even to disconnect battery for a few seconds which has clip on negative terminal connector so takes 1 second (just make sure it clicked and can't be pulled out when replugged). short hint, after connection of battery, do one start, rotated steering wheel max left, max right and to centre, then all systems will recheck and false errors will disapper (don't freak seein full list of messages on ICP - that is normal since e.g. power steering turn angle sensor needs to relearn).

 

DNA stopped working. Read this. Fuse 21 found, removed, reinserted…DNA fixed. Thank you so much ZDM100. Local dealer had told me there would be a £120 ‘investigation charge’. Now I don’t need it. I wonder if they read these forums.

 

There has always been a wealth of information on this site, I've been here since a 147JTD in 2004, currently on a MY2023 Stelvio Veloce. I don't think the majority of dealers look on here because they are not as enthusiastic as the owners!!

 

Fearing a costly repair, pulling fuse 21 worked for me too. Thanks!

 

Is there a diagramm with the fuses anyone could share please ?

 

Look here

 

By charging the phone via USB, which is located under the armrest, the fuse 21 interrupts the flow of current that feeds the DNA. I removed and reinserted the fuse and the problem was solved of my 2020 Stelvio.
Thank you for the valuable information.

 

Totally worked for me! Thank you — you are legend

 

Pullled fuse 21 here on my 2019 Stelvio. Worked great. Thanks a lot. Best wishes from Germany

 

Hi sorry to tag onto the older thread but I have following questions:

1. I have similar issue on my Stelvio Quadrifoglio V6. But I can't find the F21. Any idea where this is as per the pic attached.

2. Should the car engine be running or off when pulling the fuse F21. I am assuming one has to pull F21 and then reinsert? Is that correct.

3. I also have two other issues. Engine light is on along with DNA not working as mentioned above and but also the collision warning system light is illumintaed on the dashboard and suggest there is some issue with it (ie it has exclamation mark). I have tried to disable and then enable but no use.

Also, the mileage reading keeps blinking.

Would be great to have some ideas/tips from the very helpful people here to solve the above issues.

PS: I have recently bought the car. It's battery was flat as it had not been driven since end of Nov 24.

 

of course you unplug fuse when engine is off/ignitinon off- unless you want plenty of other DTCs logged into ECUs.

F21 fuse is in exactly the same place as shown in post #32, left side, beside nut, 10A red

DNA hanged up, so it is not responding on CAN and as proxi checked ECU now you have proxi EOL check fail and so blinking mileage, as well as check engine. If no other issues in the car, resetting DNA via powercycle will solve your all problems. May need a few starts (5) of engine to ECM decide all is fine and store DTCs as historical instead of present and deassert MIL light.

 

Thanks a million. What a life saver you are! Much appreciated. Removing the fuse F21 resolved the issue with frozen DNA as well as check engine light. Mileage stopped blinking after 3 restarts but then started to blink again.

Is there a particular way I need to do the restarts ie a particular interval or one after the other right away five time?

Collision Warning System still illuminated with exclamation mark though. Have tried to turn it on and off with no use.
