    ignition ariel

    the ariel within the ignition barrel, that reads the key chip to release the immobiliser,, can this be replaced easily or would it require the whole barrel replaced.

    the key chips are replaced an coded to the bike,, but I am still having intermittent problems when the immobiliser light stays on and the bike wont start until I go through the whole startup sequence again ,,,sometimes twice.

    I haven't seen or heard of anyone else having replaced just the Antenna -
    It doesn't seem to be available as a separate Part,
    so I imagine the complete Ignition Lock would need to be replaced.

    Before doing that though, make sure the second Key isn't anywhere near the Ignition Lock
    ( like being on the same key ring ) when you try to Start the engine, as the close proximity
    of second Transponder Chip can cause problems.

    Check now, and again the next time you have the problem,
    to see if there are any Diagnostic Trouble Codes ( DTC's ) stored,
    that may help to indicate where the problem lies.

    See this Topic if you don't know how to display DTC's on the Instrument Panel :

    Servicing Data, Reference Info. & DYTC ( Fault ) Codes.

    Scroll down to Reply #8  "Diagnostic Trouble Codes ( DTC's ) / Fault Codes."

    Why were the Key Chips replaced ?

    Do you have the Triumph / DataTool S4 alarm, or any other Alarm fitted ?

    I wonder if the re-coding process was done properly, where the Key has to be paired with the
    Immobiliser ECU, and in turn that is paired with the main ECM, and re-pairing might solve the issue ?

    Otherwise, the wires from the Ignition Lock antenna connect to the combined TPMS and Immobiliser ECU,
    so I would see if you can access that and check the physical wiring connections there.

    Cheers  :821:

    thanks coconut,
    do not have the alarm, separated the keys and replaced the battery.
    triumph in spain were at a loss as to the cause but replaced the chips in the keys and paired them to the bike. seemed ok for a while then the problem returned. it is an intermittent problem and the bike has always started after after 1 or 2 attempts.i went back to England some months ago and dropped the bike into lings  dunmow Essex they could not find any problem and checked all the wiring which was ok.
    I will check for fault  codes next time the problem surfaces, but to some extent, although annoying I have had to live with it.

    Does the problem only happen in a certain location ? -
    I've heard of similar issues as a result of strong radio signals
    such as that that may occur near military bases, affecting vehicle alarms,
    but I would think it unlikely this would affect the Trophy Immobiliser.

    The only other things I can think of are a Fault within
    the Immobiliser / TPMS ECU, or the main ECM.

    Cheers  :821:

    hi coconut
    no the problem is not in any specific location ,,, b een out today and after the problem returned,, checked for dtc codes
    p000 no faults.
    I thought about changing out the barrel and the ecu, but that's big bucks and there appears no way to test for a firm
    diagnosis.
    somedays it does not happen.
    I am still leaning toward the barrel ariel as suspect but do not have a clue as to how to test for it.
    many thanks for your input, you are a real  asset to this forum,

    I don't know what else to suggest, other than keeping a watch on eBay ( etc )
    for a Second Hand Ignition switch at the right price, buying it, and seeing whether
    it can be dismantled to swap the Aerial over.

    A New Ignition Switch costing around GBP £145, plus another GBP £15 for new Shear Bolts
    and washers would also incur the cost of reprogramming the new Keys' Chips into the system !  :087:

    You'd also be left with two different keys - the new one for the Ignition,
    and the original for the Luggage, Fuel Cap and Seat lock.  :012:

    Cheers  :821:

    The transponder cable usually fails, it is reaped by rubbing the front brake cable and the handlebar. From the ignition key there are 5 1mm section cables and two 0.50mm cables lined with a sheath, those are the two of the transponder.

    Check from when the ignition key comes out to the connector under the object drawer.
