Hello all,
I have these 6 codes pop up randomly. Last year I had new bars put on and didn't ride much after that. This year I have been getting these same 6 codes randomly. I clear them and they may be good for a few days, or a few weeks, but always come back. The radio one is leading me to think a bad/broken/pinched wire somewhere. Just looking to see if anyone has any areas to check first besides the bars, or if anyone ran into this at all. Yes it does go into limp mode and it sucks.

Codes:
ECM: 1510, 2122, 2138
BCM: B2151, B2156, and U0184

I had my right side hand controls apart looking and noticed the clip that holds the what I assume is the brake switch because it rides against the brake handle. So it may come lose or move. Not sure if that would cause that or not?

 

You may get some responses if you would tell us what the codes are saying. No one likes to look up the codes to respond.

 

Valid point. Sorry about that.

ECM: 1510: indicates that the EFI is in Limited Performance Mode.
ECM: 2122 indicates a problem with the throttle position sensor (TPS)
ECM: 2138: indicates a problem with the voltage correlation between the throttle position sensors or accelerator pedal position sensors

BCM: B2151: indicates that the left rear turn signal output is open.
BCM: B2156: indicates that the right rear turn signal output is open.
BCM: U0184: indicates a lost communication with the radio.

 

They want you to google them for them, often it seems.

 

That's only fair. I am the one asking for help. I need to provide as much info as I can.

 

those ecm codes are most likely a voltage issue. could be a broken wire at the induction module or the module itself.
did you ride the bike at all after the bar swap.

 

I would check every connection between bar controls and harness. It sounds like a pin did not get seated correctly in one or more of those connectors when bars were done.

 

Yes I have ridden the bike since the bar swap. As well as I can clear the codes and ride for a day or 2, sometimes even a week and no issues. Then all of a sudden the codes pop back up.

 

I have found 2 connectors not all the way seated in the past. So when I get home next I am just going to rip the fairing off and start from square one, checking everything.

 

once you have it started wiggle the wires at the module and see if the bike stumbles and/or throw a code.
