This is no easy fix other than reset and go until it happens again .. After happening 4-5 times that's enough for me .. What warranty is for ..

Had this problem happen to me on Wednesday. The parts to repair the problem are cheap, but they charged me 1.5 hours in labor (under warranty). I did some reading on this subject and apparently, it has been a known problem since the 2008 models. I'm a bit surprised that this subject does not get more attention. I am not satisfied that the problem is solved, only repaired and prone to fail again at some point in the future, when it is not under warranty anymore.
Where exactly is this connector and what can be done to reduce its vulnerability to vibration (one of the main causes)?
(Note to self: Need to get a service manual dude.)

There is actually four ETC modes. From Harley:
"ETC operation is designed for rider safety and continued motorcycle operation, even in the event of a component failure. The Electronic Control Module monitors the status of the grip sensors, throttle plate actuation, and airflow. If any problems are detected, the motorcycle will disable cruise control, illuminate the check engine lamp, and revert to one of the following fallback modes.
Limited Performance Mode
The rider will experience near-normal operation. The motorcycle will operate with provisions to guard against unintended acceleration.
ETC Power Management Mode
The throttle plate actuator returns to an idle detent or limp home position, which will provide enough torque to achieve speed of about 25 mph (40 kph). The motorcycles response to grip sensor input is greatly reduced.
ETC Forced Idle Mode
The throttle plate actuator is forced to a fast idle position which will provide enough torque to crawl, but not enough torque to operate at traffic speed.
ETC Forced Shutdown Mode
The engine is forced to shut down."

You're not wrong, they have it really confused. The two are in no way related. One, EITMS is a normal mode, "limp" mode is the result of a problem.

What did they do to "fix" your problem? Replace the pins on the throttle body?
