    I have the DTC 2103 Throttle actuator motor short to vBatt showing, has anyone any experience re this. Could it be caused by a dead battery or do I likely have an issue with wiring? Any help appreciated before I head off to my local stealership.

    Hi,

    I don't know much about it, but if I google what you describe.
    Possible causes:

         Throttle position sensor not fitted properly
         Wiring and/or connections defective
         Water and/or corrosion in the connector or sensor
         Throttle position sensor faulty
         Engine Control Module defective

    Possible solutions:

         Check / repair wiring and connections
         Replace Throttle Position Sensor
         Check (measured value blocks) / replace the Engine Control Module

    copied and pasted from a Dutch website.

    maybe the information will help.

    greetz,

    Road officer

    I don't know how you defend yourself to disassemble half a motorcycle and make such checks.

    The ideal is to reach the engine of the throttle butterflies and for this you have to disassemble half of the motorcycle, all the fairings, intake box, gasoline tank, etc. Locate the throttle motor connector and check for such a short circuit.

    Anyway, I think that with the TigerTool or DialerTool you can check the operation of the accelerator motor.
    Only motorcyclists know why dogs stick their head out the car window.

    The service manual is not very helpful for this DTC - It just says, "Contact Triumph Service".

    Looking at the wiring diagram, the "Throttle Control" ( Presumably the Throttle position motor ) has two wires.

    One is coloured Blue with a Brown Stripe, and the other Blue with a Green stripe.

    Bear in mind that these are the main harness colours, and if the sensor has a short fly lead
    with a connector to connect to the main harness, the wire colours at the sensor may be different.

    These two wires connect directly to the main ECU - Pins A02 and A03 respectively,
    so IF you can access them, it should be relatively simple to disconnect the ECU plug, and test for short circuits
    and continuity of the two wires.

    If the wiring tests good, this would most likely indicate a faulty Throttle position motor.

    The motor is not listed as being available as a separate part, only as part of the complete Throttle Body Assembly :
    World of Triumph / Trophy SE / Throttle Injectors & Fuel Rail.

    In view of the price ( Approx GBP 1800.00 ) if it IS the Throttle motor that is faulty,
    it may be worthwhile searching eBay etc. for used parts.

    Cheers  :821:

    Thank you for the responses, I now know why I got what I thought was a bargain buy. I will get it to my local spanner twirler and see if he can diagnose the cause, I don't think I could swallow the costs associated with taking into triumph. Thanks again. If anyone has more information that would be gratefully accepted but I think it's definitely a dig in and see what happens job. Cheers guys.
    I will update when I find out what is happening.
    Quick update Coconut you art a star man my mechanic was well pleased with the info you provided and I managed to nab a throttle body assembly on EBay for 185 with 6 months warranty, if I need it I have it if not it can go straight back on Ebay. Thanks again all. Will update once the works done.

    So took the bike to my trusted local guy (not a triumph dealer) we discussed the issue and he agreed it "could" be a short circuit in the wiring or an issue with the throttle body, he also thought it could be a spurious DTC caused by the bike being laid up for a long period before I bought it, as he has seen these on Triumphs before. So he hooked up his laptop went through the reset procedures and cleared the DTC code. Covered about 200 miles since between snow storms and so far no recurrence of the DTC code. I am taking this as a good sign as physical electrical problems tend to not cure themselves.

    That seems like Good News then !  :152:

    Spurious Codes can also appear if the Main Battery is allowed to drain,
    or just by disconnecting the Main Battery - particularly if the system
    hasn't completely shut down before doing so.

    Thanks for the update  :028:
