    Digital Speed Sensor

    On my morning ride to work I noticed my digital display was not showing my speed.  I tried to turn on the cruise control and it wouldn't work either.  I am assuming there must be an issue with the digital speed sensor which then affects the cruise control.  Has anyone had issues with this?  I live in MD in the USA and it is winter.  The temp this AM was about 23 degrees riding into work.  The cold hasn't had any impact on it before.

    I as well as many others have experienced what you describe. When the temps warm up, the digital speedo comes back, even on the same day.

    The most recent discussion, that I'm aware of, is here: https://www.triumph-trophy.com/index.php/topic,7913.msg93897.html#msg93897  There are others, I'm sure.

    Yeah,  I am curious to see if it is working after work as the temps are suppose to be a bit higher.  From what I gather, however, this should not have affected the cruise control but since it is the first time the digital speed and cruise haven't worked I will wait to see if when the speedo comes back (hopefully) the cruise does as well.  If not I will try the reset sequence.  Speaking of which (this is a dumb question but you know what they say) when you run through the sequence you do each step and then release before moving to the next step, correct?  So if doing the sequence below you pull the front brake and then release.  Then press rear brake release, etc.  correct?

    The conditions are Ignition key on (engine not running) and cruise control switched off :
    The switches should be activated one at a time in sequence
    Activate front brake switch
    Activate rear brake switch
    Activate clutch switch
    Activate twist grip switch (push the throttle in the closed position)
    Activate cruise on/off switch
    Activate cruise accelerate switch
    Activate cruise decelerate switch

    Hi mwj1042010,

    You are correct in your assumption about releasing the various switches after activating them..

    ... otherwise it would be impossible to complete the last two steps !   :164:

    The Cruise Control system uses the Digital Speedo to operate, so if the Digital speed is not displayed,
    ( due to the cold - which is "normal" and mentioned in the Owners Handbook - Page 40 ),
    then the Cruise Control won't engage - as other Members have confirmed.

    I'm confident that when the temperature rises enough for the Digital Speed display to re-appear,
    that your Cruise Control will also be up and running again without needing to carry out any reset procedure.

    WHY it does this in the cold weather we may never know - it just does  :190: !

    ( Triumph would probably describe it as a "feature" !  :745: )

    Cheers  :821:

    In my experience, when the cold temperatures (sometimes as high as +3DegC) cause the digital speed readout to blank, this has no effect on the cruise which can still be engaged, and the display does show the engagement speed as normal. I once rode for 1 1/2 hours at -4DegC with no digital speed readout but with cruise working fine. I would find it very annoying indeed if the cruise didn't work when the temperatures were a little low!

    That's weird !

    I haven't experienced this issue personally ( yet ! ) ....
    my comment about the Cruise control using the Digital Speed reading / sensor
    ( which I think is still technically correct ),
    was based on other Members saying their Cruise Control didn't work
    at the times when the display was blank during cold weather,
    but as your Cruise Control continues to work in this scenario,
    this is now another "mystery" of the Trophy Ellectronics !  :087:

    I assumed that the digital speed readout was turned off in cold temperatures to prolong the life of the display (being as it is likely to be constantly changing - except when on cruise). This wouldn't necessarily affect the sensor and other related electronics.
    The last occurrence for me was on Sunday evening when I headed south to Bristol. To begin with the digital readout worked (my garage temperature was +5C), then as the temperature sank to +2C, skirting the moors north of Manchester, the digital display went off. But the cruise still worked fine. Later the display came back on (although the displayed temperature was still +2C) so maybe some engine heat had worked up to the display? The display remained working then even though the temperature dropped to 0C.

    The temperatures look similar for my return journey tonight.
