I am not saying that you or others haven't experienced this problem. My argument is that there is something else going on that causes this condition and that it doesn't set a DTC. But puts the TBW assembly in the limp home position.Oh BlackDawg, I have read the 2 pages you referenced in your last post, and both pages are concerning potential fault codes that can be registered as failures and stored in the ECM.
If you were really as observant as you claim to be you would have noticed earlier in this thread that when the ZERO throttle position of the ETC is stored in the ECM it does NOT set a DTC. And if you were to read page 40 of your owners manual you would also learn the the ETC feed the ECM which them feeds the throttle body.
And I realize that using your hand to reach over and turn off the ignition is too complicated of a ritual for you to learn, so however you are doing it, I hope it continues to work for you.
I am guessing that has been your experience? NO DTC? If it is a fact that shutting down re-writes the IDLE position in memory they would all do it. So did I get the only one that isn't broken? I doubt it.
My reference to the manual was to float out there, that there is a potential for your bike to not find Zero at the throttle body when turning the ignition on. Guessing that it reverts to Limp Home where it started at initialization. In that senario, there is no DTC unless it happens for four consecutive ignition cycles.
Curiously, I don't see why the system would need to write the TGS position to memory. If in fact TGS1 is 5v and TGS2 is 0v at the grip's idle position, the system should know it is in an idle state. What are the voltages when the throttle is rolled completely forward?
I apologize if I sounded like a know it all. However, if you read enough of these threads, you will get the impression that nobody has actually worked on these problems. The dealers don't know what to do other than tell you to cycle the ignition. The Moco has identified what it thinks the issue is and has a download for it. Without troubleshooting while it is broken. The fix is nothing more than an educated guess.
