    Will I not be able to clear the codes and get my car out of limp mode just like the OP has been doing via OBDII via my MFD when the time comes?

    Also, can anyone tell me what my old codes mean before I clear them? They are in the picture I attached.

    I think @uart down in OZ milked a weak Gen2 HV Batt for quite a few years.

    There are no meaning to those codes, you need to read them via OBD reader.

    Hit 218K yesterday. Went to Louisville and back about 650 miles. No problem with the battery. Again, seems like after a long road trip, the battery seems to hold the charge longer.

    This would be a good challenge for Hybrid Automotive , they should loan you a Prolong setup and see if it can fix your battery .....

    I’ll probably fry what good remaining cells I have left in my battery. Probably better for me to drive out to California and back to fully recondition the battery.

    Found this thread end hoping someone can help me with some info.

    I have a 2010 prius with 150k miles on it. Earlier this year my cousin borrowed my car, ran it out of gas which then caused the hybrid warning lights to come on and the car wouldn’t start again even after gas. Found out through here that it was a common thing and then had to pay dealer to reset codes for it to start.

    Now I got some warning lights yesterday. Took the car to autozone to have them read the codes for me and was told it says replace hybrid battery. Car drove fine back home and drove me 20 miles to work this morning as well, but the triangle light is still there with the warning saying to check hybrid system.

    Is my battery really bad if it’s still driving normal and hasn’t actually required a reset?

    Also, if I were to choose like OP to just try to run this battery as far as it’ll take me, how would I keep resetting the codes if it (I’m assuming) shuts off and won’t let me drive until it’s reset?

    Please forgive me as I’m not privy at all with this kind of stuff and probably even butchered the question. I appreciate the help!

    1) a 'hybrid specific' code reader can often tell which cell in the battery is having difficulty. Cells can be balanced or replaced cheaper than the entire battery. Most code readers only read engine codes, a Prius has at least 5 computers all sending different codes. If you have an honest dealer or hybrid mechanic, it may be worth while to have them diagnose it.

    2) Resetting the codes is as easy as removing the cables to the 12 volt battery. If there is something wrong, they will be back shortly.

    3) as mentioned in 1), now it may be fixable, while if you let it run with one cell not helping, the entire battery may be at risk.

    Thank you so much for this thread! This has been extremely helpful!

    So, what is the OBD2 reader that you are using to reset the code? (or better yet, what do you recommend for Gen 3 Prius?)

    Thank you! what did you end up doing with your car, keepdriving?
