    So i was driving my prius to pick up a rider. Unspectedly the car made a sudden pull/ slowed down. Turnit off and on and still got the following lights.
    hybrid system warning light, pcs, brake system, check engine, slip indicator light on.

    I ended getting the car towed. I thought after having off for a bit it might go away. Unfortunately they are still on. In a bit i will scan it with the obd2. But any suggestions as to what im about to spect?

    There are many INF or sub-codes associated with those two trouble codes. If you can get the sub-codes for each trouble code, it will help pinpoint the problem area. That being said, it could be an inverter/conveter problem that might be covered by a Toyota extended warranty. Consider taking it to a Toyota dealership for diagnosis.

    Yeah but before you get it towed over there and get a bunch of money in tow fees they should be able to look up your VIN and determine whether that is the case or not if you have the code which I guess this is that but before because it's not going to cost you much to get an inverter that's up to snuff from the junk yards LKQ will let you have one for $75 or something they don't go bad often enough. Seriously I used to have them laying around here all over the place I guess through them out because they were too much trouble to save I have one of each now or generation two and a Gen 3 and they just sit here they've never been used yet and any of my fleet anyway. So the few that slipped through that haven't had the campaign done or whatever if they're going to give you a bunch of grief and it's not going to happen it's nothing to worry about just go buy one from LKQ or wherever you can find a wreck they're not worth three or $400 or anything like that anybody that tries to get you like that to just trying to gouge you because they think you don't know unless you live in some absurd market.

    Well tomorrow I'm getting an inverter. Hopefully that solves the problem.
    Question, what code would i get if there's a problem with the battery??

    P0A08 is the main code, but sometimes you get individual 'weak module' codes

    Typo?

    P0A80 is the code for "Replace Hybrid Battery Pack"

    Good news everyone. Just wanted to update everyone. I just finished replacing the inverter. So as of now all the light cleared up. Took it around a few blocks and it's running fine.
    FYI for those who have never replaced and inverter and are novice. Put a small container to catch all the coolant that will be coming out.

    Ok guys so another update. Before experiencing the problem with the inverter. I has noticed that every time i filled the gas tank, i was getting a lower mile range, down to 335 miles for a full tank. I was going to remove the ekg and i take manifold to clean it from the carbon build up on my next oil change. But after changing the inverter, i am now getting a mileage range of 450 for a full tank.
    Just an FYI
