    Unplugged Connector Question

    Now, I'm assuming the pics show an unplugged diagnostic connection, but I don't know if it's supposed to be plugged in normally, or not. Reason is, I read that the white female connector is just a holder for the male connector. But, there's two pins in the female connector, which begs the question. So do I plug it in to run, or not?

    Yes plug it in. That’s what it’s intended for. The two pins could very well be to tell the ecu everything is normal or to complete a circuit that’s only interrupted when in diagnostic mode.

    Is this a 2018?

    I noticed a similar unplugged connector this past weekend. Machine has 12 hours on it now, has been running fine without it plugged in so I wasn't sure what it was meant for. I figured it may have been for the plug and play USB charger that I don't have?

    Anyone with a 2018 have a similar thing? Seemed less than ideal to have a connector bouncing around...

    It's a 2016 RXT 260. New last year, and was serviced by dealer before storage. Just noticed this, when I moved it out of the garage to start. Dealer is closed on Wednesdays.

    On older models, it will display a check engine if the diagnostic end is not plugged in.

    that diagnostic connector should always be plugged into either an analyzer ( like a candoo) or it's it's special cap ( there is a resistor in there) . if it gets submerged, bad things will happen. very bad.

    sloppy tech not to plug it back in. Sometimes the cap goes flying off and ends up down in the hull somewhere. I find lots of skis missing the cap completely or the connector wrapped in a sandwich bag.

    and the ecu knows when that connector is not plugged in and records it as a fault.

    Future reference for anyone the 18 is made to the coolant reservoir.

    Will the fault go away after it's plugged back in? I started it just to make sure it would start, but only for a second or so, as I didn't have a hose hooked up to it. It was after that I noticed the disconnected harness. Don't know if it threw a code.

    the code won't be active, but the ecu will list it until cleared.
