Electronic Control Unit I do believe.
Electric Control Unit
what does it do and will prevent my transimission for working? Where is it and would it be hard to replace?
Tranny not working?? Does it not shift? Check the angle sensor first. If it will not shift.
ECU in the Rubicon would be tied to the trans I would think, thats the brains for the automatic.
I agree
The ECU controls everything on the rubicon including timing Spark, Transmission, and so on. With No ECM bike is a big paper weight.
