2021 Supra SA Electrical Issues

[Marc Taylor]

Supra has been having issues with the new steering wheel controls. I just had my boat out today first time since my 20 hour service and the SW controls don’t work.

There is a diagnostic module for the thrusters, if you use them hard, they over heat and you need to be going less than 5mph and have over 11v

What was the fix on steering wheel control malfunction? My new 2022 SA 400 has the same problem. Also her we go again, first day put in water not charging and low voltage warnings!!!! As soon as you accelerate charging decreases!

The fix was to let the screens fully shut down and then let them fully boot up prior to starting boat.

Had no loss of SW controls since.

Interesting on same charging issue on your new boat. Perhaps your dealer is not setting up battery/wiring correctly?
