DTC codes
A few weeks ago I went to start my bike and it turned over alittle slower than usual but started as usual, pretty quick. On the way home the ABS light flashed for a while then went out. Bike ran good as always. I got home and looked to see if there is any codes. There was a code for ecm,bcm,radio,and the abs
All codes numbers= loss of communication.
I cleared all codes to see if they will come back.
This morning it turned over like last time and on the way to work the ABS light flashed a few time and went off. I checked for codes and they all were the same, Loss of communications
Just for the hell of it i checked the battery and its got 12.4v with key off. Ill check it with key on and see if it still has 12.4v
Whatta think ?

Standing voltage is one thing but what really matters is cranking power, so take it to an auto parts store and have it load tested.
You should also check that the battery cables and ground connections are tight and clean.

Lost comms usually indicate a low voltage condition .
1 check battery
2 check charging system
3 check gounds and connections
if you cant get to a shop that will load test your battery a old automotive trick is to hook up an analog (needle gauge ) volt meter and watch the needle when you crank - should not drop below 8-9 volts , a fast deep drop in voltage is usually an issue with battery . Your battery has to have the reserve capacity to start the bike while still supplying 9 volts to the control modules .

Iv checked all that was suggested and everything is good.Battery good,all grounds checked and cleaned and charging system working.
Just a thought I changed bars over last winter. Im thinking maybe a wire there is shorting out? Is the wires for the ECM,BCM running up through the bars?
Im what to make sure it isnt something I did before, taking it in for warrenty work
