I hope someone can help me. A couple of days ago I replaced the batteries on my 2008 Supra Launch 21V. After replacing them I got a "SERVICE REQUIRED" message on the screen and can access any of the functions. I read that a way to reset the code is to run "3 heat/cooldown cycles (engine runs above 150 deg then below 100 deg, 3 times)", can someone please walk me through on how to run the cycles. Is it just to run the boat until it gets to 150 deg shut off and then let it cool down and run it again, and so on for 3 times? Any other ideas? Thanks!
