2015 Ultra Classic - I just replaced my battery and now I have no throttle response and will not idle for long. Was told to pull Main fuse to reset ECM. Did that and now it's throwing all the codes for TPS 1& 2 and EFI management. Anyone experience amnything like this or know how to reset TPS and EFI signals?

Thx Ron

 

Changing a battery is about the same thing as pulling the big fuse, total power loss to the bike. Are you sure there isn't more to the story, such as a handle bar change, wiring in a new accessory, or even a handle grip change? Are any add on items also connected to the battery? Are the connections tight? If this really is just a total coincidence, disconnecting, cleaning, and reconnecting all of the plugs between the twist grip sensor and the ECM, either all at once, or one at a time and testing after each one is a good place to start. Did you disconnect the ECM or anything else for easier access to the battery during the change. Recheck all connections disturbed by the battery change. Some bikes came from the factory with tension on the wires going into the plug that connects to the throttle actuator and a wire finally breaks from vibration.

 

my 14 sg was giving me similar issues. took it to 5 dealers finally 5th one replaced the calibration on my ecm and bike runs fine again. still not buying that was the issue but 55 bucks later the bike runs great again.
