    I have a 2007 Toyota Prius I'm having trouble with there's no check engine light but the SC light is on but triangle is on and yellow! Is on in the fuel gauges full and flashing the car turns on at first and I can start to drive it but after a few feet then miles per hour goes blank and then the car won't start unless I reset the battery cable and reset everything and then it'll work for a few seconds again the gas engine is not coming on I don't know what to do

    It's time to get a capable scanner on the car and see what codes you have because of those lights Is the exclamation point in the circle on the VSC light We know is on and what about the ABS light in yellow That's right next to the VSC light Is that on? Then what display goes out The miles per hour or the MFD the TV in the middle of the console? If it's the miles per hour gauge gas gauge etc first thing you want to do is check your 12 volt battery and all its connections If it's any kind of out of range that needs to be dealt with first. Then a simple test is to open the door of the car when the battery is correct Do you see the icon that shows you that the door is open It's in red no? If you don't see that no matter what you do to start the car it may start and run you'll have no display miles per hour or gas gauge close the door and open the hatch look at the dash Do you see the icon that tells you that the hatch is open? This is where we'll start

    Last I checked, the Gen 2 repair manual was missing the info on what the different fuel gauge blinks mean, but they seemed to be very close, if not identical, to what they meant in Gen 1, as described here. Which blink would you say you've got?

    You mean the factory generation 2 repair manual set it's like three books thick That's missing this information that's in the gen 1 manual or is this all in Chilton stuff? I'm just curious to know. I'm trying to purchase an original three manual set by the pictures that the guy took of the manuals they look to be the factory Toyota manuals books 1 through 3 for the 2009 American market Prius the generation 2 in other words I was hoping that these would include pretty much everything with nothing left out not that the gas tank blink codes are seriously important and that was wild how that other guy's car they had to rip apart the dash to check an inclination sensor holy crap yeah I think my gas gauge would be flashing a lot longer than 3 years I know I go 412 miles and it's time to be getting gas without any problems Go longer than that and you might have an issue so there's always that. But in all of the electrical and weirdness of the cars never had a problem with the gas gauge other than it takes a few minutes sometimes to level off I never ever do anything but fill up the car not $5 worth $10 worth half a tank none of that nonsense I cram all the gas in there until it belches and then slowly fill it until I can see it right there at the filler hole but not dumping on the ground screw on the cap and off I go I'm going to stretch that bladder out like a pregnant woman's tummy if I can.

    Just like it says in the linked post above, in the Gen 1 2001 manual, the info on the fuel gauge blinks appeared on a page numbered DI-661-1 inserted between pages DI-661 and DI-662. So it seems like they had nearly forgotten to include the info in the Gen 1 manual, and even though they made a last-minute save with a page insertion, they still forgot again to include it in the Gen 2 manual. At least it's not in the old edition 2006 PDF that floats around. Maybe it's been added if you sign in to TIS for the latest version.

    Yes, when I say the repair manual it's the Toyota one I mean ... if I'm ever talking about some aftermarket third-party book I'll name it.

    By the way, when you're signed in to TIS, they do have a way to contact them about missing info or mistakes in the manual, and I did that once and they did get back to me, so it doesn't just go straight to the round file. But this particular omission isn't one I ever reported.

    Yes I've had a TIS login when I worked at Toyota in the service department years ago It worked for several years after I left the company I can't wait to get my hands on the three manual set in paper The Toyota version I also have a chance to get a UK version if I want it so we'll see I hope nothing's missing from these manuals I don't mean taking out by somebody but not put in there to begin with I never saw this before and other Toyota publications I have manuals going back to the mid-70s 74 75 Corolla /trueno.

    They're written and edited by people, so they're very complete and done very carefully, but some things do fall through the cracks.

    That's one of the good things about using the manual online at TIS. Your paper copies will always be missing the same things they were missing when you bought them, but the ones online keep getting fixed as errata are discovered.

    It is flashing full

    The ABS light is not on and check engine light is not on and what goes out is the zero mph you know how when you're just sitting there and drive it says 0 mph well eventually that disappears in the fuel gauge starts flashing full

    I would say I have the first blinking where it's even solid blink there's no blinking pattern at all and when all of this problem started I had to u0100 code pop up and check engine light but now could be because I unhook the battery

    *ALSO THE TROUBLE STARTED WITH A P1121 CODE BUT I FIXED THAT AND BEFORE I FIXED THE COOLANT VALVE I GOT A U0100 CODE

    Also I do see the cabin open door light on yes the dash circuit board I've been replaced from one in the junkyard where somebody had put their own capacitor on to replace the faulty one that comes from the factory and the car had been running for 30,000 miles plus no problem

    Yes I do see the hatch is open light

    Then you should have zero on the display in your gas gauge and your shift pattern for the transmission is also shown right? The capacitors that capable people generally replace on the CM monitor display board are like three look at Texas hybrid site they'll show you I think there's three or four capacitors they replace all at one time not just one The one they did for me is working beautifully like it's supposed to no issues at all and from looking at the back when I got it before I remove the little beep speaker it looks like they've replaced three capacitors from all the other units I have in this box and that goes with what their description says.

    So if that's just the bar segments, I think it would be the communication error, and if it's the bar segments and the E F letters, it would be the fuel temperature sensor. The old U0100 would also make me lean toward communication error.
