    Angry 2001 gtx di

    So as we all agree the DI is great but f..in pain in the a$$. I got this thing for 650$ and started fixing it, whole pump was redone, new regulator, new plugs, battery, oil tank was leaking and sealed, gauges replaced, new gas in it, drive shaft was changed. The ski runs more than amazing, however after a few runs at full throttle it goes into the lovely maintenace mode or limp mode, limiting it 4800 rpm, idle it for a while and it goes away. i know it should be plugged in and read the codes, went to my local dealer twice paid 125$ for diagnostic and he gets every error he can poisbly get, he cleared and told me to take it out again and bring it back after. so i did that and when i bring it back again his comuter shows almost all the possible failures you can have, however he tells me since it runs good most of the time that the jet ski is fine and the limp mode might be caused by a fault in the electrical harness...? any ideas how i can get rid of the limp mode? thank you

    instead of continuing to throw money down the dealer hole, pick up a candoo code reader for $400..you got a good deal on a DI with a running motor.

    every possible fault tells me that the "tech" ( and that in MAJOR sarcasm mode) doesn't know how to read a report.

    a di will show every possible fault along with the time it happened and the number of times it happened,

    threw me off the first time I looked at a di issue with my candoo..but I eventually tracked the problem down to a malfunction in the rave control solenoid.

    it will be $400 well spent as three of your Seadoo pals will think you are a hero when you make keys for them down the road....

    limp mode comes in to protect the engine and rider from damage..but according to group k's web..limping a di causes major damage!

    how many hours on the ski?

    hey there so reading through GH i figured out that you can find faults on the dignostic computer by looking at the fault count, took it back and looked with the mechanic and the mag tps had 2 fault counts, everything else was zero and clean, will put new sensor in and see what happpens, hopefully thats the end of problems, 227 hours on the ski plugged in. 350 on the gauge since gauge was replaced from a different ski, thank you

    So dealer changed tps and reset it and it still goes to limp, he says he doesn't know what's wrong according to the fault count in the buds computer and he's now asking me for 700$ so he can start swapping parts and try and fix it, thAts more money than I payed for it, and I'm not ready to pay that. Also I understand I should get a candoo but its 400$ and that's not including the price of parts once the problem is found, is there anything else I can try before I go broke on this ski ?

    In that case I would pay the dealer for the parts, but not for the labor, since they don't have the knowledge to correctly repair your ski.

    A di with a problem can be a quick trip down the "shouldn't have gotten involved road" if the repair shop wants to start "throwing parts at it"

    That also applies to woman named after big cities by the way.

    you could always part the ski out and call it a day.

    Thankfully he's not charging me for anything, but the ski still has hope to see better days, when its not in limp mode, it runs amazing, and limp mode comes and goes, if only I could get rid of it....

    The DI Fault system is probably the least understood part of diagnosing and repairing DI problems. In fact, many dealer technicians do not understand it, so we have a section within the CANDooPro help section to help our customers to better understand how to interpret the information before trying to diagnose problems.

    The DI fault system is actually a pretty powerful fault logging database. It has all possible faults listed in a table, with STATE, COUNT, FIRST, CLEAR, and LAST columns. To make this short, the STATE and COUNT columns are mostly used to diagnose most faults. Every time you have a limp condition, it will increment the COUNT number by one during the time the ski is run.

    The problem is that DI's tend to throw lots of faults. So when a ski ends up at a dealer with a problem, the tech sees a table full of count values for lots of different things, and therefore has no clue where to start looking. What you are supposed to do is clear out all the fault counts, then run the ski until you get another fault, then stop, read the ski and the problem component will easily show up by a 1 in the COUNT column.

    Your tech knew enough to clear the COUNT, I am surprised he doesn't know what to do from there.

    For a very intermittent limp fault, the Candoopro system provides a very powerful tool for the home user, as when it happens, you can immediately hook up and see what is causing the intermittent problem. If you continue to ride, you may throw other non-critical faults, and when you take it to the dealer, the tech is left with trying to sort out what is actually wrong out of 3 or more COUNT values....

    without access to this fault database you are simply throwing away your time and money.

    You'll be spending plenty of that if you have to replace bits of the fuel injection system

    consider it an upgrade to your ski and find out what the computer has been doing

    then you can have some level of confidence when you buy some parts to fix the problem that comes up every time.

    But continuing to pay somebody who isn't fixing it?..well time for the tools you need to fix it yourself, just as good at this as the dealer tech ( in all fairness, how many of these di skis have these guys actually worked with?..not a whole lot I would think), cept you have a whole bunch of folks here who have seen a wide range of 951 problems. fair chance with the fault report and some help here, you can resolve this without too much additional pain.

    If it were me I would have already bought the CanDoo. Think of what you will save by not taking it to a dealer every time something acts up. 2 trips to the dealer will probably buy the CanDoo. Also, don't even consider what you paid for the ski when it comes to doing repairs. Consider what a good running, problem free similar machine could be bought for.

    Do the carb models have less problems than the DI? I am seriously considering selling my DI for a carb model... would you guys say that is wise?
