Ich würde den Händler direkt mal kontaktieren, evtl. nachfragen, ob du versuchen kannst sie mal Stromlos zu machen (batterie einige Zeit abklemmen). Danach wieder anklemmen und checken ob der Fehler noch immer da ist...
Als Beschreibung ist im Netz u.a. folgendes zu finden
(Zitat - http://www.manualslib.com/manu…/Yamaha-Mt09.html?page=27)
This model is equipped with a self-diagnosis device for various electrical circuits. If a problem is detected in any of those circuits, the engine trouble warning light will come on and the display will
indicate an error code. If the display indicates any error codes, note the code number, and then have a Yamaha dealer check the vehicle. The self-diagnosis device also detects problems in the immobilizer system circuits.
If a problem is detected in the immobilizer system circuits, the immobilizer system indicator light will flash and the display will indicate an error code.
TIP If the display indicates error code 52, this could be caused by transponder interference. If this error code appears, try the following.
1. Use the code re-registering key to start the engine.
INSTRUMENT AND CONTROL FUNCTIONS
TIP Make sure there are no other immobilizer keys close to the main switch, and do not keep more than one immobilizer key on the same key ring! Immobilizer system keys may cause signal interfer-
ence, which may prevent the engine from starting.
2. If the engine starts, turn it off and try starting the engine with the standard keys.
3. If one or both of the standard keys do not start the engine, take the vehicle, the code re-registering key and both standard keys to a Yamaha dealer and have the standard keys re-registered.
NOTICE
If the display indicates an error code, the vehicle should be checked as soon as possible in order to avoid engine damage.
Und evtl. kann dir auch das noch weiterhelfen:
