2017 John Deere Gator 590i - No Spark

I have a 2017 John Deere Gator with only 142 hours that has no spark on either spark plug....I have replaced the coils and it has a new battery. Everything else works with the key in the run mode, lights, winch, starter, fuel pump, dash computer and I have 12 volts to the coils.
There is a light on the dash computer that shows a manual and wrench indicating a ECM error but nothing in the user manual for retrieving any ECM error codes.
Any ideas on how to retrieve the error codes on this model, (without hauling it to a JD dealer) it does not use a standard ODB tool. Any ideas on what could be preventing the coils from providing ignition spark to the plugs?
