    DCT + Kill switch while riding, what would happen?

    Ok, this may be a silly question, but...

    What would happen if you are riding your DCT CT, say highway speed, and as a joke a friend of yours rides up next to you and hits your kill switch?

    Obviously the engine would shut down, but would the bike go into neutral? (normally if the ignition is turned off while in gear, the bike remains in gear, and the clutch is let out)

    Would the bike stay in gear, and if you turn the kill switch back on, would the bike just fire right up?

    Would the bike stay in gear, and when you turn the ignition back on, go into neutral?  you then can restart the engine with the started?  and can you put the bike back in gear while still rolling?

    And in a slightly different scenario, what happens if you run out of gas while on the highway? does the bike go into neutral? or just keep rolling with clutch pulled in?

    hi Tazmool, i dont have the dct but i imagine that as the kill switch had been flicked and as power has gone then the bike would remain in gear and then hopefully roll to a stop, it could i suppose lock the back wheel.

    Wifes auto car cut out altogether once and it rolled to a stop as a manual would do, but we where only travelling at no more than 10 mph.
    i wouldn't like to try it at speed on a bike.

    If you where running out of fuel then i personally would be riding slower to get more miles hopefully, so if running to a complete dry tank i think the same should happen you'd roll to a stop but with still having power on it should stay in gear and stop as if to a stall.

    only surmising and im probably wrong but someone with a dct may shed more light on the matter.

    Good luck with a better response Tazmool.  :028:

    Happened to me recently as it happens, was switching from manual to auto and I inadvertently hit the kill switch at the same time, but didn't realise I had done it at the time, my only sensation was that I had lost power and coasted to a stop, all I did was turn the ignition off, then on and turned the kill switch off then back to run and it started as normal.

    Indeed, same happened once to me.

    After reading the responses I figured, what the heck, lets try it and see what happens!

    So, bike was in 4th gear, 50km/h, in D, I then hit the kill switch...

    The bike lost power, the tach and gear indicator went blank, bike slowed down a bit, I then turned the kill switch back on, and bam, tach is back, bike is back in gear and power is back...

    I did notice something strange though....
    There was no engine or oil light on, with the kill switch off...

    So I tired it again...
    Normal response, gear indicator, tach both go blank....
    However, engine light is not on, and oil light is not on....... ???

    Is the engine still running???

    I gave it throttle, (while coasting) and it sure seems that the engine responded! 

    I'm wearing ear plugs, so I can't hear my stock exhaust, but the engine sure feels like its revving up a little as I twist the throttle....
    I twist the throttle a few more times, and every time it seems like the engine is revving up a bit, it sounds like its barely running, but its running...

    That explains the no oil light, and no engine lights on.

    I flip the kill switch, and bike is back to life like normal...

    I then pull over, put it in neutral, hit the kill switch... Engine shuts off, engine light and oil light both are on...  its definitely down.
    Flip the kill switch, re-start engine, its back to life...

    So, it seems:

    With a DCT, while riding, if you flip the kill switch:
    The engine keeps on running
    Tachometer goes blank
    Gear indicator goes blank
    Rest of instrument cluster stays on and indicating whats going on (speed, temps etc)
    No engine or oil light comes on
    It appears the clutch pulls in so bike is free-wheeling, coasting to a stop
    You can give it a little bit of throttle and engine will rev up, but reluctantly
    Gears do not shift (so when you put flip the kill switch, its still in the same gear as it was earlier, everything goes back to normal, tranny shifts if it needs to)

    That is my story!

    Well, that's comforting to know, thanks for the experiment.

    Hello,

    So my test results...

    2016 Highlander DCT-T

    Going down hill at no more than 10-15mph in D. Flicked the kill switch. Engine died and appeared to be coasting - Oil Pressure light came on. Did not drop into N until I stopped the bike and then it went into N. Also whilst rolling flicking the kill switch did not bring the engine back only the dashboard came back to life but no N indication.

    Tried again.... Its a big hill! Engine died and appeared to be coasting. Whilst still rolling and in indicated D tried to start the engine. No go. Would not go into N whilst rolling. Had to actually stop and allow it to go into N before restarting and carrying on.

    Maybe it behaves differently if you are going faster?

    From this I deduce that you couldn't bump start it if you wanted to?

    Not sure if that helps or confuses!

    Best regards,

    David :028:

    Hello,

    To add to the above. Engine is still engaged as I roll down my hill but at exactly 12mph on the speedo with the kill switch off it seems to disengage and you can't do much until you stop completley and it changes into N.

    Prior to reaching 12mph you can flick the kill switch back on and the engine will start.

    Best regards,
