HELP. 4 beeps engine light on no start

[Swat0375]

Turn power on, place Dess on post, fires right up. Use start stop button and will continue to work. The moment I pull the Dess key off post or turn battery off and put key back or or power back up from battery switch the check engine light comes on and it will not start. I get four beeps regardless of what is going on. Please help. 2005 Seadoo challenger 180

I’ve check neutral switch and has good current flow, I even jumped it to make sure and it didn’t fix it. I believe it’s in the Dess post. Any suggestions
