    I have been researching 2nd gen Prius' and they seem to be very reliable. I've got an OBD2. My question is what codes should I look for that break the deal on buying one. Any help would be greatly appreciated.

    What programs do you use for OBDII?

    I've got a bosh code connect. I'm not sure what you mean. Forgive me, I'm not tech savvy when it comes to this.

    Okay. Do you have an Android or an iPhone?
    Maybe a laptop with a special cable?

    For Android you can use Torque, Dr. Prius, Hybrid Assistant.

    It's a hand held system with a cable that hooks up to the car. No laptop or Bluetooth. Just a hand held 300 dollar unit

    Not all OBDII scanners work equally well with different cars. For Toyota, Techsrteam is recommended.

    I don't have the money to buy another one. The one I have now reads live data streams, codes, and a global system. If I'm not being clear it's because I don't know that much about them.

    There are options
    A. You connect your scanner and it does not damage the car, but it does not give you the correct information
    B. You connect your scanner and it damages the car, because it is not designed for its use.
    C. You connect the scanner and it does not damage the car and gives you the correct information and the correct codes.

    Okay. I know it doesn't damage the car, but I don't know if it's giving the right info. But I appreciate your time. Thank you.

    Are there any signs of malfunction on the car you are buying?
    Is the check engine light on?
    Is the red death triangle on?
    Are other error indicators red or yellow?

    I checked out an 08 and it had an Abs code which might be very bad I heard. What I was wondering if I can tell by the voltage of the battery is about to go out and if the 500 dollar part for the brake system is bad.

    I don't know what it meant but the same 08 had a reading of low voltage and high voltage. I'm not sure what that means.

    A high-voltage battery cannot be checked with a regular scanner. The check is good in dynamics, when the battery is discharged and charged, the parameters, voltage, current and internal resistance of the modules are monitored.
    An error in the ABS unit is serious. This can affect the safety of the brake system. And of course, the costs of restoring the work, spare parts.
    There is a method for reading errors with a simple paper clip. In the OBDII connector, short-circuit pin 4 and pin 13.

    Okay. I heard the brake system had a 500 dollar part and if it goes out it costs about a thousand for labor. I also heard that the gas tank can have major issues too.

    Is there any way to check to see if the head gasket is blown.

    The problem with the gas tank is that it is not disassemblable. The fuel pump and fuel filter are inside and cannot be changed.

    All things considered, is a second gen worth buying. I doordash for a living and a car is essential. If the Prius goes out I'm in a bad situation.

    How much is the car worth now?
    How much do you expect to sell it for when you stop using it?
    How much do you expect to drive it in a year, in two?
    How much to spend on repairs?
    How much.... Many unknowns.
    The Prius is economical. You can find many good parts at junkyards for next to nothing.
    But any car ages over time, requiring additional investment.
