Hi,

I just finished the rebuild of my engine after a valve floating.
i wanted to clear all the defaults codes but I can't connect to the ski and I get error 301




it was working before even with the engine out the hull (I had to read the VIN)

I've checked all the sensors, the harness etc etc I dont find anything wrong

what can it be ?
