Worth a rebuilt hybrid battery?

    So I'm having a few issues here. Hopefully they're all easy fixes.

    For starters, I bought two ODBII code readers and both won't read a code at all (even when different "bad" dash lights are on). Either I'm an idiot or something's amiss. So I can't give you a code. Sorry. (last one I bought was a 400$ CA and was a hit and miss; the 2005 Prius was on it's list of compatible cars).

    This week I noticed the green light on the big power button doesn't light up anymore. The orange light works fine however.

    Now last night I decided to install all my new the #5 bolts on my battery pack. They're all snug and tight.

    The car starts perfectly fine BUT I have the wollowing issue. When I start the car, it goes into accessory mode. I have to press on the start button again for the car to start.

    As a side note, the tank is nearly full but I get the blinking "50km left" indicator (but no message on screen).

    It seems as though the more I work on this car, the worse it gets?

    Any insight is, as usually, massively appreciated :)

    There was a reason for that advice.

    Can't say I have ever heard of "the wollowing issue". What is that?

    There are very few scanners other than Techstream and a few several thousand dollar tools that do a good job with most of a Prius' modules. The xtool line is an exception according to some reports. The XTool Anyscan A30M Wireless OBD2 Scanner (with no update fee for different vehicles) for Android & iOS might be worthwhile at $219.

    But for battery data and a decent sample of Prius data, the free Dr Prius or Car Scanner apps along with a $27 elm327 bluetooth adapter services me. If you get absolutely nothing from your obd2 scanners it is likely user error.

    OK now car starts normally /!?&&
    I didn't do anything.
    Drove my girlfriend to the voting booth (it's elections here in Quebec) and everything was good.
    The gas also shows up properly.

    More info on the ODBII reader : the last reader I bought was able to evaluate cells, two by two. Worked fine. But it still wouldn't read the codes. I swear I read the instructions line by line. Garages here are asking 100$ CA to read the codes so I'd rather put 100$ on repairs.

    It requires several attempts after disconnecting the 12v.

    As said above, these are both indicators that the 12 V power was disconnected at some point prior to the restart attempt.

    The first time after reinstating 12 V power you need to press the power button twice while also pressing the brake pedal. The first press puts the car in IG-ON and the second press moves it to READY (all things being equal).

    The fuel gauge will blink until the car has recalibrated the fuel level. It could be anything from 5 mins to 5 days.
