    I have an older VDST Scantool. Will it work with a Weber Marelli ECU

    You may have to go under Ducati to see if the MIU ECU is listed.

    John, the MIU would be hiding under Aprilia (scooter). I am not aware of any Ducati that used the MIU.

    Has anyone found an workaround – seems ridiculous to have to pay a dealership to literally delete via the P.A.D.S software.

    Does GuzziDiag take care of this?

    I read the first post, and from a discussion stand point, it doesn't really answer the question I asked.

    I am confused. It seems more like any person who writes about "G u z z i D i a g" is black listed?

    I'm only asking other riders what they have learned.

    Hi Guys, I am having an issue with this error Code - Error code B0008 (ALARM DISCONNECTED). Below is the explanation and that can be done to revolve the issue. I am handy but new to the Guzzi world and have difficulty understanding what it means or what to check. What's happening is that the bike shuts off when I am going up the gears (2-3) and I then get the error above.

    Occurs during the encoding of the first key connection, if the CAN line from the engine control unit is missing, the error is activated
    Identification
    · General alarm warning continuously on (red) and indication "ALARM DISCONNECTED" on the display

    Troubleshooting
    · Check the integrity and the continuity of the cables of the CAN line between PIN 8 instrument cluster and PIN 27 injection control unit and between PIN 1 instrument cluster and PIN 26 injection control unit
    · Further check that in the CAN line is no continuity with the vehicle mass or with positive

    What model do you have?

    Do you have an alarm fitted?

    I have a 2017 V7 Stone and I really couldn't tell you. I got it used so I don't have much of the history of the bike.

    If you do not understand this, then this should tell you one thing. Take it to a qualified Moto Guzzi mechanic.

    I'm sorry, but this is the truth and will save you much heartache and aggravation in the long run.

    Thanks for the advise but didnt join the forum to take it to a mechanic. Just needed a bit of direction.

    Does the bike start at all? If no, this is an error message that the ECU gives on screen when reading/writing to the ECU. It could be that the ECU is corrupted by third party ECU software (happens often). If this is the case, there's no way to correct it outside of ECU/Throttle Body replacement. About all I can be of help with here.

    That’s the weird part. It does turn on just fine and even after the shut off, I can ride it. But at a certain speed or shifting from second to third, i get the error message and the bike dies.

    Darwin,

    I didn’t tell you what I did to be a douchebag.

    I told it to you because you don’t have the necessary preliminary knowledge for the conversation that needs to be had to solve your issue.

    But...I’ll give it a try anyway...

    You need much more than “a bit of direction” my friend... Sorry.

    The text above says the following:

    The error that you are seeing displayed, NORMALLY, is an error that occurs when trying to register keys to the ECU.

    The keys have a microchip encoder inside of them, that are introduced (programmed) to the ENGINE CONTROL UNIT (ECU), through a process of cycling the master key in the ignition, followed by cycling of the primary key, and secondary key, etc This process links those keys microchip code to the ECU, so that the ECU knows these to be authorized keys.

    It’s part of the theft deterrent system.

    However, this error normally would occur during this key programming process, and not while just riding the bike.

    IF it were occurring during key programming, then they want you to check continuity of the circuit on the CAN bus (wiring harness)

    “between PIN 8 instrument cluster and PIN 27 injection control unit “

    and

    “between PIN 1 instrument cluster and PIN 26 injection control unit”

    This requires looking at the wiring diagram to identify the location of the wire.

    You then need a multimeter with very fine leads to connect one lead at the one end (pin 8) and the other lead to (pin 27), and use the continuity function of the multimeter to verify that the wire is intact and transmitting the electrical signal (you are checking that there isn’t a short or grounding out of that wire).

    You then check the same thing for the other wire (pin 1 and pin 26).

    If neither of those 2 wires have a problem, then they want you to check than the individual pins previously checked, have no continuity (connected circuit) between them and either the negative polarity side of the electronics (i.e. the negative battery or the chassis of the bike which is negative) and that also they do not have direct continuity to the positive side of the battery.

    “· Further check that in the CAN line is no continuity with the vehicle mass or with positive...“

    Now, in reality, you should not be seeing this particular error while riding the bike. It makes as much sense as a charging light lighting up on a car that isn’t even running. It makes no sense at all.

    So, these types of unusual errors typically have 2 causes. 1 - a poor condition battery. Take the motorcycle battery to an AutoZone or large corporate auto parts store, and they can “load check” the battery FOR FREE, to determine it’s state of health. It may be in poor condition and causing your ECU error.

    NOTE: Battery Load Testing is not the same thing as simply reading the voltage across the battery terminals! It’s very different indeed.

    STOP! AFTER YOU REMOVE THE BATTERY BUT BEFORE YOU TAKE IT TO BE LOAD TESTED, GO BACK TO PAGE 2 OF THIS THREAD, AND FOLLOW MY DIRECTIONS FOR RESETTING THE ECU TO A GROUND STATE. IT CAN BE RESETTING WHILE YOU ARE AWAY.

    The other cause, #2 - If the battery checks out okay, then Todd is most likely correct in that somebody previously performed a direct access to the firmware written on the ECU, with software they got on the internet, and the ECU is now corrupted, which if this is the case, the repair is both long and VERY expensive as it would require the ECU to be completely replaced with a factory one and new keys to be programmed to it to function correctly.

    My only two questions at this time are:

    1. if this happens every time you ride the motorcycle?

    and

    2. Are there any modifications to the bike wiring, like did somebody change out the turn signals, lights, etc?

    If you see this exact same error, exactly the same way every time, it is most likely a corrupted ECU but again, have the battery load tested and give us your results as a first step.

    A proper Moto Guzzi dealer can connect the Piaggio computer to your ECU, and immediately determine if it has been overwritten or corrupted, but they will charge you for this service.

    Post back the results of your battery load test.

    Good luck!

    FYI:

    A CAN bus is not like a standard wiring loom. They are much more complex and sensitive.

    Major thanks on the explanation. I just want to learn about the bike and how it works and should the issue be out of my league, talking to a guzzi mechanic. Now the key could be the issue; the cylinder was changed as the bike had no keys (rebuilt bike). I’ll have to ask as my friend to verify. Mostly likely he just installed the part without this knowledge. I’ll work my way down the list.

    If all else fails, take it here. hamlincycles.com They are up to date on the new bikes.

    Thanks John, but I am really set on getting it fixed. With the amount i paid for, even if i have to replace the ECU +labor, in the end is still a steal.
