the fretting is known issue...I would say, because of all the different codes that it is probably a voltage problem going to the control module....when the voltage drops or spikes it thinks all kinds of weird stuff is going on....so, check your voltage at the battery and the battery itself (load test it) ...also check the output of the regulator for either high or low voltages...
Buddy of mine just went thru this. Mechanic said it's almost never the grip sensor. Almost always the throttle body/actuator connector. YMMV.

Ok, I went out and started playing with the bike.....
If I shake the ECM/ECM Connector... or barely START to release the latch on the ECM connection, it throws all the codes I listed before. So I am guessing it is the Fretting issue.....
Now.. can anyone tell me the way to fix it? Maybe with Pics?

Pappy,
Since the pin contacts are molded into the EMC I had to replace the EMC. The terminal and wire in the mating wire harness that goes between the EMC and the Throttle Acuator had to be replaced as well. The wire terminal can be pushed out of the connector harness at both ends and replaced with a new wire and crimp terminals at both ends. Then dressed through the cable harness. Connector types and terminals are listed in the Service manual. Use Dielectric grease on all contacts when done. The grease helps lubricate and seals the pins preventing this from happing again. If there is already freeting I don't think that just applying grease will do much good. The terminal is gold plated and the fretting increases the resistance at the connection. The ECM is looking at a small (millivolt) difference and any increased resistance changes the value read at the EMC.

Just got done talking to Harley when I picked up the part number items for the fretting issue.
Their telling me the only thing I can safely use to crimp these new conenctors is a Harley only crimp tool that is only available to dealers.???????
Does this sound right????
