    Default Unknown undescribed problem

    I`ve recently filled my tank with BAD fuel. Motorcycle was delivered from the road to my garage and I started to check all. Changed fuel completely - still could not stard. Then I`ve found that my rear spark plug MELTED. Changed it with new one. No start. Cleaned injector and IACV and finally started.
    BUT.
    Now I can not go to D mode because the "-" indicator constantly blinking. There is no error codes. It`s just CONSTANTLY BLINKING
    There is no descriptions about this in both service and owner`s manual.
    The dealer does not know anything about this.
    Can anyone ask dealer or someone else what does it means?

    Hi spamer80
    Personally I cannot imaging what would cause a spark plug to "melt" but the fact that you could replace it and start the engine is promising.
    If the indicator light is flashing at 7.5 second intervals that suggests that there are no codes stored.
    For me, if you haven't already, initially I would disconnect the battery for 5-10 minutes and reconnect and see if the "system" resets.
    If that fails page 11-21 suggests there is a "fail safe function" which stops the bike from going into gear...worth a look.
    Failing that, on pages 11-26/27 there are 7 possible causes for non operation of neutral/drive. 9-1(9), 9-2(9), 17-1(17), 19-1(19), 31-1(31), 41-1(41) and 42-2(42).
    Finally, page 11-28 tells how/when to re-initialise HFT
    Personally i don't see how dirty fuel could affect the HFT.
    Perhaps the overheating/melting of the rear spark plug has caused the system to go into lock down as a safety precaution by creating a sensor trip (the fail safe on page 11-21).
    I would go thru pages 24-25 just to be sure that all dtc's are cleared.
    Hope you can get her back on the road soon
    I don't believe how complicated these babies are!!
    I don't think my Goldwing was even this complicated.

    I know about 7.5 seconds, but it continiously blinks every 1 second or maybe faster (have not tried actually to measure) .

    I`ve also tried this. I`ve tried to disconnect both battery, TCM and ECM.

    I`ve read all this too. But this is not a code, just blinks.

    The blinks does not allow to do this. I can`t re-initialise HFT while it`s blinking like this.

    Me too, it wasn`t after bad fuel. It`s started after injector disassembly and cleaning. Maybe I`ve just clamped some wire somewhere, but I still can`t find it.

    I can`t read DTC and can`t clean DTC.

    Personally I feel that the 'new' problem: "flashing dash" in HFT is self-induced when you took the fuel system apart to be cleaned. Seems to me that something wasn't re-assembled right or shorted. I would be checking the wiring to/from the HFT unit because the bike now starts and runs. It seems like "somewhere" on this forum someone had a similar problem or had gotten that flashing indication too. It just sounds familiar. Sorry I couldn't help more.

    Thank you for your reply. The bike sometimes starts, sometimes not (when you close the throttle, it won't hold idle). I've found that this is because of IACV, it's kind of stuck or something like that. Removed all plastic from bike today and right now going after oil pressure sensor. In other topics I've described tcm error 45 indicated sometime, when I turn ignition on or try to go from D to N. Next month I plan to buy new iacv, new n/d solenoid valve and if it will not work - new TCM.

    UPD
    One good former dn rider gave me an idea. Can anybody check, what the bike shows on dashboard when you stop the engine with kill switch while in "D" mode and also when you open kickstand in "D" mode?
    I surely tried to run it both kickstand open and closed, but I need the indication.

    Neutral oil pressure switch was changed yesterday to the new one. No effect. And I`m not sure if it was "slow". I`ve seen the slow blinking before (eactly error 45(1)) and it looked very different and much easier to read.

    But thanks.

    Bike running, "D" selected, Kill Switch ON: Red and Yellow lights lit, "D" indication NOW "FLASHING" single bar ... sound familiar!

    Bike running, "D" selected, kickstand open: Green, Red, and Yellow lights lit: "D" indication NOW blank.

    I hope this helps somewhat

    Local dealers are NOT the most knowledgeable about the DN-01 since it's so rare ... at last that is how it is in The States.
