If you're having problems with limp mode engaging at the wrong time, you can just turn it off. Don't remember exactly how, but check the owners manual - its in there.

You can disable the EITMS .. Limp Mode being caused by Code P1511

19. P1511 Throttle Actuator Control Power Management Failure of Throttle Control Actuator ...

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 ..

 

I never go into limp mode — or my bike either :-)

 

Will never happen on my EVO either, sometimes wonder about this new improved **** ..

 

maybe im wrong -- but you guys got limo mode and EITMS mode all confused.. there is a big difference between the two...

 

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.

 

I would also worry that the problem is not cured-only temporarily fixed. Seems like we get a thread on this every week or so, do a search. HD design/engineering is really sucking at fixing this. I don't think they care (imagine that). This is beyond ridiculous.

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

 

My ECM was replaced under warranty .. Waited a few days to respond as been leery of it happening again .. But after 200 miles feeling a little better ...
