I have been having an alarm "Engine Transmission Communication Failure", This alarm doesn't have any effect on performance, doesn't go into Limp Mode but my speedometer or tachometer doesn't work while it is in alarm. The problem started when I power washed the unit after getting in the mud. I had my dealer look into it and he was unable to find the problem. He thinks it could be the ECM but so far I don't agree with him. I'm reluctant to spend that much money on a new ECM and have it not be the answer to the problem. One of the techs at the dealership mentioned that it could be a speed sensor. Has anyone had this problem with their UTV?
