    Stupid Code 48...

    All help with this problem would be appreciated...

    A couple weekends ago, I was out jumping waves when the low fuel beep started acting up. I figured it was a stuck float or a bad connection, and I ignored it.

    Last weekend, the fuel gauge would sometimes work and sometimes not work, but the ski ran fine. I also noticed that the stock tach was inop when the fuel gauge was inop. Then I landed a jump and the ski just shut off. I could get it to start, but it would run rough and stall every time. Had to get towed back through 6 to 10 foot seas (FUN!). The ski was giving me a code 48 - incorrect data transmission.

    I got the ski home and disconnected every electrical plug I could find. They all looked good, no corrosion or loose connections. I slathered them with dielectric grease and reconnected them. No help - fuel gauge and tach inop, code 48. The ski will run on the trailer, but it idles at about 1000 rpm.

    The local dealer is less than enthusiastic about touching the ski, so I am on my own here. What should I check?

    Yes, it has a controller and it appears to be functioning normally. I put it in there last year so it is fairly new.

    I had one give me that code and it was the terminals pulling outta the controller connector. Also the smaller grey connector right under the hood goes to the cluster.

    I wish it was one of the EFI connectors, but they were all clean and tight, and the terminals were fine. I guess I can bypass it and see what happens.

    The fuel and tach inop problems may or may not be related to the problem. What are the possible causes for a code 48?

    Incorrect data transmission is a communication error

    OK, I unplugged everything that goes to the display - buzzer, speed sensor, ECM, oil level and fuel level. No changes.
    I can't get any code out of it anymore, though.

    Idle speed on the trailer is 1250 to 1450, just as the book says. Although, the book calls it "trolling speed," so I would assume that is IN the water.

    So - bad display? I haven't put it in the water, so I don't know if it will run right as is...
