OK B1005 is "Fuel Level Sending Unit High/Open Instruments" with the U1016 "Loss of ICM/ECM Serial Data Instruments " indicating that there is an issue with the sending unit in the tank, has anyone been in the tank? Has the connector on the tank under the console been connected? Both codes will be thrown if the connector is not connected and the fuel pump will not run. That connector goes to the fuel pump and the sending unit.

 

 

FuelMoto's website has most of the codes but Dr. Google helped with the B1005 code. First thing I would check is under the dash and ensure that the connector there is connected, this will provide power to the fuel pump and signal from the sending unit which is most likely your issue if you are getting these codes. Otherwise you may have a failed fuel level sending unit (this is a variable resistor attached to a fuel float inside of the tank) to check you could drain the fuel from the tank and check the resistance on pins 2 and 3, fill to 1/2 check again and fill the tank to full and check a third time. Below is from the 2005 Softail service manual but should be similar on other models. Additionally I would also check the fuel pump fuse and ensure that it isn't blown otherwise on the connector going to the tank panel under the dash I would check for the momentary 12vdc at the Pin 1 (Orange/Grey wire) to ground to see if it is getting power (easiest way of doing this is a 12vdc test light, connect 1 side to pin and the other to ground then switch to ign position light should light for 2 seconds if not you have other issues).

 

 

 

 

As stated in post 10 - if bike sat for years with gas in it, pump and lines are junk.

 

Ooooh Nasty, this is not going to be cheap. I have seen some complete assemblies on Ebay for around $225 US but not many for the softails.
