I recently bought a used Seadoo and discovered the dirty little secret of personal watercraft that they don't want you to know. Unlike cars with their standardized ODB2 ports, those aren't a requirement for PWCs. And the diagnostic scanner hardware/software costs hundreds or thousands of dollars. Major affront to the right to repair, so I'm ending up doing some CANbus hacking.

That’s kinda surprising. In Polaris ATV’s they seem to have this built into the interface of the machine itself so you can read the codes on its LCD. I don’t know how complex they are but I assumed they were a bit more open than OBD-II instead of less.

It has an LCD that'll give you a "problem" (low 12v) but won't show you sensor values, stored codes, disable limp-mode, etc.

You can tap a few buttons and get trouble codes. At least on the 2018 or so Sportsman I had. This feature was described in the manual, if I remember correctly, and all the trouble codes were well documented. It would show things like “P0012” which then said “high voltage to xyz”. It was very similar to OBD-II systems I’ve used.
