    motor management warning light

    Good evening.
    Because of the corona-problems this year we hardly have done tours. Last saturday we did. The motormanagementlight did not go out. Before the gear-indicator stayed in first.
    After a restart that started to function again. Warning light for motormanagement still burned.
    I used to have a Tiger 955 i. A couple of times the same problem but after some (5?) restarts the light went out. Will that go the same with the Trophy or is it adviceable to vist the dealer.
    Thanks in advance for any adequate reply.

    When the "Malfunction Indicator Light" or "MIL" ( Engine Management Light ) remains ON,
    a "Diagnostic Trouble Code" or "DTC" ( Fault Code ) is usually stored in the ECU.

    DTC's can be displayed on the Instrument Panel without needing any specialist equipment.

    Read this Topic for details of how to display the DTC's :

    Servicing Data, Reference Info. & DTC ( Fault ) Codes -

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

    At the end of that message, you will find a Link to download a document that explains
    the meaning of any DTC's that are stored ( "P0000" means there are NO DTC's stored ),
    together with further information about how long they are stored for etc.

    Note that the "MIL"will remain ON until the there have been a certain number
    of "No Fault" starts, usually 3, and the DTC will remain in the ECU Memory
    until there have been a greater number of No Fault starts, usually 40.

    It is therefore important to check and record any stored DTC's
    ( Mobile Phone cameras are really useful for this ! ),
    especially where there is an intermittent fault,
    so the DTC can be recorded and investigated before it becomes erased.

    DTC "P0705" is "Gear Position Sensor Malfunction", there may also be others.

    Once you have determined the DTC number, there is a reference in the above document
    to the Section of the official Service Manual that deals with rectifying the issue.

    Cheers  :821:

    No problem - Did you find any DTC's on your Trophy ?

    Let me know if I can help with anything else  :028:

    Hello Coconut, sorry for the delay, but here I am again. The faultcodes I have found are: P0705 (gear-indicator) and P1577. The last one is related to the switches for brakelight. Correct me when I am wrong. I contacted the dealer and they say that there have been more problems with the gear-indicator sensor, not only Trophy but also Explorer. There seems to be a new type of sensor available, cost about 100,-. To reach it the fuel tank must be removed he says. That means probly another 100,- working time.
    For me it would be important to be sure that the sensor is the reason. During the wintertime there will be time enough to repair it myself and it would be very helpfull to know what to do and where to find the parts that need replacement. I do not like to order parts that will not be needed.
    Might it be possible that it will come ok by itself. There is nothing that does not work. Only that little orange light that comes in my eyes time after time.
    I do hope you can give me an adequate advise one more time.

    Hi barbarosa,

    I believe the Gear Position Sensor ( Part Number T1290660 ) was updated,
    but that is only from comments made by other Forum Members,
    I have no personal knowledge of this.

    I do know that your Dealer is WRONG to say the Fuel Tank needs to be removed
    to replace the Gear Position Sensor !   

    The Gear Position Sensor is located on the left side of the engine
    just forward of the gearchange input shaft. 

    The Service Manual describes the process thus :



    The "Gear Linkage Cover" is held in place with one bolt at it's forward end,
    which becomes accessible after removing the Fairing.
     
    It's a fair amount of work to remove the Fairing just to uncover that one bolt,
    but is not a difficult job - See this Topic if you have not removed the Fairing before :
    HOW TO: Remove the Fairing .......
    There are also two pegs that are held in rubber grommets at the rearmost section of the panel. 
    After removing the bolt the cover will pull away to become free of the grommets.

    With regards to  DTC P1577 ( "Brake switch 2 correlation error with brake switch 1" )
    check to see whether both brake switches ( front and rear brakes ) are working,
    or whether one fails to cause the Brake Light to come on.

    The most likely cause of the DTC is a faulty Brake Light Relay,
    so I would try changing it for a new one,
    assuming there is no obvious damage to the front or rear brake switch wiring.

    The Brake Light Relay is underneath the Right Side Panel,.
    It is a light blue colour and is the same type as the two Relays used for the Screen.
    ( Part Number T2506035 ).
    You could try temporarily swapping the Brake Light Relay with one of the Screen relays
    to see if this allows the DTC to be cleared.



    Any authorised Triumph Dealer can obtain the Gear Position Sensor and Relays,
    or you can check places like eBay using the Part Numbers quoted,
    or order them from "World of Triumph" in the UK - there will obviously be additional shipping costs to add !

    Let me know how you progress with the investigation !

    Cheers  :821:

    Thanks a lot Coconut, this is a great help. I looked at it already and think the only things that need to be removed are the two small black pieces of fairing, the one with the plug in it and the smaller one just above. That is not a lot of work, I did it before.
    About the brake light: during my last tour there were problems with the brake light: the fuse went a couple of times. At home I cleaned plugs and checked wires. Found nothing but after putting things together it all worked without problems, taillight, brakelight and horn! Of course it is not sattisfying not to know what I have repaired, but important is that it is all right now. Hope it does not come back during the next ride.
    During the coming winter I will work on it and will keep you informed.
    Thanks again for the clear explanation and the drawing.

    No problem - One more thing though :

    Have you had the Ignition Wiring Safety Recall / Inspection carried out  ?
    ( Click the Link in my Signature below to find out more ).

    If there are faults with this Wiring it could be the cause of faults within the Brake Light circuit.

    Cheers  :821:
