    Hey Everyone,

    After having a few cells replaced in my HV in the past year my car nicely told me its time to replace the battery the right way. The only problem is I am up in LA for work this week...I live 120 miles away.

    The car drives normal on the short drives from the hotel to the office and back I have taken this week, the battery fan is not blowing like it has when things like this happened before. My question is am I going to do insane damage if I try to get myself home...or at least somewhat of the way home to lessen the tow fee? I have accepted the fact that during the 120 mile drive my cars going to probably die. Am I being a total dope? The alternative is an expensive nice person long tow home or trying to find someone here to fix it but I don't really have the kind of job where I can split for a few hours to get my car to a mechanic or the dealership.

    Elvis,

    Although every situation is different, and your results may vary, if you are early in the failure time of the battery, you will probably be ok.
    Are you sure you have a HV battery code?
    Do you have a way of resetting the code if it trips?

    Are you going to be travelling relatively level/flat roads?

    Hard to do any DIY repairs when you are on the road and working. And I guess that you do not wish to spend a lot fixing a 2005 at any rate.
    Any chance of turning up a used HV battery at an auto wrecker there? Sometimes in life, you have to just tough it out, driving may be necessary, like it or not. Good Luck...

    I can give you a hand with a tow if you need it, I get 100 miles free from AAA. where exactly in Los Angeles are you?

    You might have a failed inverter pump, which has similar lights to a hv battery problem

    I'm not 100% is the HV, but i have a sneaking suspicion it is. I think tomorrow I'll disconnect the 12v and reset and see how it acts. Its mostly flat to San Diego, maybe 2 or 3 hills.

    Hi JC,

    I'm in El Segundo. That's an amazingly awesome offer. I might take you up on that. There's a dealership in Manhattan Beach a few miles away, I'm going to call them up and see what sort of turnaround they can do on a HV Battery for me. Or maybe my 12V reset puts things back OK for that one last drive!

    edit - I'll check the Inverter pump tomorrow too, just started reading about that this week while scanning through these forums. My car was fine the entire drive up here from San Diego, only when I stopped at the store right by my hotel and the turned the car back on did I get all the warning icons.

    Have you read the codes yet, this time around? If you haven't, you're just kind of assuming that of the hundred or so possible reasons for your dash lights to come on, this is necessarily the same reason it was last time. (You've even mentioned that symptoms, such as the fan behavior, are not exactly the same as before, which might be a reason to question the assumption.) Ultimately, no matter what your issues were last time, we don't know what your issues are this time until you have the codes this time.

    That could help form a more confident judgment about how much of your 120 miles you're likely to cover. :)

    I bowl Tuesday nights lol. But the OP may not be far away.

    It might not even be a battery problem

    I bowl on Sunday mornings with my son;).

    $1 a game from 6 am through 10am:).

    Since we are up anyway (at 7 he has no concept of sleeping in on the weekends) it’s a cheap hobby(y).

    Good points. Although I have a hunch since I had a Prius mechanic replace a few bad cells twice in the past year and have sort of been waiting for things to go bad again...but hunches are not facts.

    I tried to see the codes this morning but I think because I was parked at a slight incline it wouldn't let me into diagnostic mode as it kept informing me of being on an incline. I'll have to try after work.

    Also looking ahead, if its the HV, would I be silly opting for a reconditioned green bean with their 5 yr warranty and getting a maintenance grid charger....or paying over double and getting a new one at the dealer, or would a moderately mechanically inclined fellow like myself be able to purchase a new one and install it without dying?

    If it is the hv battery and you’re already considering a Prolong setup, why not do the module swap and reconditioning yourself;)?

    I helped a member up here in the Bay Area do that exact thing:).

    Still running well. Just another idea (y).

    Well, even after having my car go into low power mode with the Main battery warning light on the MFD I was able to limp the 120 miles home. Leaving in Friday afternoon traffic sort of helped as traffic rarely went above 25 mph. I'd be lying if I said I wasn't waiting for the battery to just explode at some point...hah.

    LOL, Maintenance mode, but I'm assuming that's not the correct way? Can I get a code reader from an auto parts store on lend or do I need to buy one?

    When you say "maintenance mode", what do you mean?

    The system check screen on the MFD ? It disappoints everybody to find out that only gives codes for the infotainment electronic stuff.

    For the car diagnostics, you do need a scan tool to plug in at the DLC3 connector. The ones that will give you access to the most information would be J2534 dongles connected to a laptop running Toyota's "Techstream" app.

    In a Gen 2, there are also a lot (but definitely not all) codes that you can retrieve by just putting a wire between two of the DLC pins, and counting blinks of lights on the dash. Kind of old-school, but you can do it wherever short bits of wire can be found, whether or not you own a snazzy scan tool or have it with you (and it gives you a kind of direct-to-the-car sanity check of the scan tool you're using, if there's any question about the information it's showing you).

    Doh, thanks. Well I'll see if any auto parts place has a loner for me to scan my car with, otherwise maybe I'll pony up and buy one. I imagine the one they sell on this site is the go to model?

    If you might invest in something, search around for threads about Techstream.

    But before (or while) you're searching for that, you can certainly get whatever codes are available as light blinks, if you can get your hands on a wire.

    Those won't include HV or battery codes, but as of now we don't even know whether the codes you're (not) seeing are HV or battery codes or something else, so it's worthwhile to at least get the something elses checked for.
