V7 850 trouble in paradise
« on: November 30, 2021, 07:41:45 AM »
So I really love this bike but this is the second time it’s left me stranded. First it was the kickstand switch and I bypassed that and ran for quite some time. At 5600 miles it has decided to not start. It flashes a message “alarm ecu disc”. Any thoughts appreciated.

I'm guessing that "disc" might mean disconnected or disconnection.  Check the main plug for the ECU, it may have become unseated.  Good luck.

You might want to have it checked w/dealer software.

On the eve of my departure for my 2014 Europe trip, I went to start my Norge and an “ECU disconnect” warning came up on the panel.
It turned out to be a buggered rely.
ECU disconnect warnings are not necessarily ECU related. If you have Guzzidiag, you can check for a code.

According to the User+Maintenence book
"ALARM ECU DISC" means "Electronic Control Unit disconnected alarm" -
If no connection is detected, the instrument panel indicates this anomaly by displaying the "Alarm ECU Disc" text

Page 33 of the English text.
Relays and fuses would be a good starting point. Also disconnecting the battery for a few minutes might allow the ECU to reset.

Appreciate the responses going to take it to the dealer. Will update. Would a bad kill switch do this?

No a kill switch doesn't give an error.

The dash and ecu are connected over CAN bus. What the thing is, the dash can't talk to the ecu, so it tells you the ecu doesn't talk. The ecu is in the throttlebody integrated.  So getting no power or failing a ground contact could be a thing. Or the connector on it could be not seated.

So to add to the comedy of this situation my wife's car broke down and I'm almost done fixing that(turbo gave it up). Then same day the Guzzi threw a fit her bike threw a tantrum which turned out to be bad gas. Her bike is running tip top now no issues. so rather eventful week. I will update as things progress. Several guys from my fire station are helping me load up the bike today to go to the dealer so this should be interesting.

So included here is a poorly marked up picture to protect the guilty….. we got the bike loaded without incident and lifted it into my friends pickup after work. We made it to the dealer without issue and they will start diagnosing tomorrow.


The second picture is me in process of replacing the turbo that went out. Thought maybe you like to see the adventure.

2 minutes to change the turbo and 4 hours to get to it and then put everything back. Been there, sucks.

Good luck with the bike, hope it's simple!

Thank you for your encouraging words. I got an update today that the computer hasn’t shown any problem codes for the V7. It continues not to start and the dealer has informed me that the tank is removed and they are trying to hunt loose wires which will take some time. I will keep everyone posted. It seems I have offended the automotive Gods as my wife also picked up a flat tire to add insult to injury and necessitated a new set for the other car. So hopefully this will even out. At least the cars are paid for.

Well, at least there's no trouble with the plumbing at home, hopefully.  Hang in there Beowulf, and thanks for the update.

Appreciate the laughs. I must admit Im really curious what this turns out to be. More than anything I'd just like to know for peace of mind because prior to this the bike ran great.

When my Stelvio did the eco disc code it turned out to be a dying battery. Replaced battery and it never happened again. Hope your solution is as easy

Man if it’s that simple that would be the way of it. But on a new bike seems unlikely. Was it an older battery?

Further update the tech says it is dropping voltage to the fuel pump and everything else. He has further disassembled the headlight and continued to trace wires. Everything is hooked up to the ecu. So should be interesting

I see a reliable bike in the background of the first image, no doubt looking on with amusement:)

It doesn't need to be with batteries these days. Here's hoping the tech jumpered a good battery into the system the first thing he did. It would be embarrassing if it was a dud battery.

I don't have a wiring diagram.  Does this bike have a "bank angle" sensor (tipover sensor)?  I chased these symptoms for a couple of days on Beaver's baby breva.  Turned out that the sensor, located behind the battery, was sharing space with a mouse.  I cleaned the nest out and re-leveled the sensor and the bike started.

Just a thought.

Honestly a good thought. I really don’t know. I’ve never dropped the bike ( knock on wood) so I obviously haven’t seen if it has one. I will keep it mind if they are stumped I think the dealer is tired of me calling for updates. This is my ride to work so I’m kinda of anxious about it but it is nice to have my wife’s royal Enfield handy. Really great bike. I’m just addicted to Guzzi. The jokes got me laughing. I hopefully have my turbo manifold bolts coming today for my 2007 Mini Cooper. My wife is currently driving the 2006 Mini as it has reliably been plugging along. Anyways lengthy post I will stop myself here.
