    DTC Code P1698 is often thrown up when the Main Battery voltage drops,
    or when there is a poor battery connection problem,
    which are the most likely reasons if there are no other apparant symptoms.

    My advice would be to check the condition of your Battery,
    and ensure the Battery terminal connections are clean and tight.

    The "MIL" ( Malfunction Indicator Light / Engine Management Light )
    will be extinguished for this particular DTC after 3 "no fault" starts.

    It is possible this DTC may also be thrown up as a result of any poor connections
    resulting from the Ignition Wiring Fault - now subject of a Worldwide Safety Recall.

    Cheers,

    Thanks Coconut.  Your technical input is always valued. 
    The voltmeter tells me I have 12v over the points (bike not operating because it won't start).  I tried re-tightening the terminals - no success.  I checked the starter fuse and that's okay and while there, checked the regulators, etc., were seated properly.  All good.  I have tried over 4 times to shut down and restart and it's not going anywhere.
    I ride nearly every other day but the bike has been sitting for about a week.  I then tried it after washing it.  That could all be coincidence and irrelevant but its hard to fault find without adequate info (just watch Father Brown or any of the other whodunits).
    It's weekend here today and my next move is to take it to our local mechanic who was the former Triumph dealer before closing.

    From what you describe, the main Battery could need replacing,
    and that would almost certainly be the cause of the DTC Code you had.

    Before buying a new Battery, see if you can get it fully charged, and then tested by an
    Auto Electrician with the proper Battery Testing equipment.  I suspect a new Battery will be needed.

    IF the Battery is found to be good, then in addition to checking that both terminals at the Battery
    are clean and tight, you should check for any signs of corrosion and clean terminals / contacts
    within the Main Fuse Holder located close to the Battery - pull the Fuse out to inspect.

    You should then move on to check the connections from the Battery to the Starter Solenoid
    ( located just forward of the Battery ), from the Starter Solenoid to the Starter Motor,
    the Negative side of the Battery to the Ground connections, and the Alternator output connection,
    which will probably require removal of the Fairing and possibly the Fuel Tank to access everything.

    There are a few previous Topics from Members who had electrical problems
    due to corrosion of the terminals on the main Battery cables ( Part Number T2502504 ),
    including this one :

    Headlight minor flicker - wiring loom issue?

    Hi Coconut
    I took the battery in for a load test and it turned out to be the culprit.  I owe you a beer next time I'm in the aulde country.
    Thanks Mate

    I just wanted to say I've had this code twice in the last four years and both times it was the battery that caused the issue.

    bjtourer, I noted you didn't mention what year your Trophy was. Mine is a 2016 with 90 thousand k's on the clock and I went to start it and just got a click, nothing more. After recharging a load test showed not enough to even turn it over. Failed cell, new battery fixed the problem. After that long and constantly operating two sets of LED driving lights, GPS, heated clothing [when needed], headed grips and heated seat for the good wife I think it was about time for a new battery. $120.00 Aus. cheap at twice the price. Just another item that requires replacement when worn out.
     I often wonder if I come into that category.  :008: :008:
