    Yes, but it requires OEM software (Techstream).

    There are however, a number of DIY tests that can be performed to gauge, not measure, the HV battery capacity. One particularly useful one involves running the car to fully charged (Green bars on the battery meter) and then seeing how far it will drive on the electric motors alone at like 25 MPH. You need a LIGHT touch on the accelerator and a relatively flat road for this.

    welcome! you can test the battery modules for current health, but there's no guarantee what you will find when you wake up in the morning. all the best!(y)

    Thanks bisco, like any used car buy, problem can happen, just hope to get 2-3 years (+/-30000miles) of reliability. Might try the test that 05PreeUs says. Used to have some 2004 where I used to work and they were pretty reliable.

    generally speaking, they are very reliable. my neighbor has my 2004, 150,000 miles, no repairs. all the best!(y)

    I did the math, on the fuel savings alone v Toyota Camry, we can *afford* to replace the HV battery with a NEW OEM one every four years and still be money ahead.
