    I am not that familiar with TIS and data capture (got my cable yesterday) so I grabbed a couple screen shots.
    What I am experiencing is quick hv bat discharge on hard acceleration and of course the triangle of death (twice). I am not sure of the acceptable parameters of the IB amps, normal cell voltages etc (wish I had captured data a couple years ago).

    Pic 1 key on ofter sitting for 4 days
    Pic 2 after a minute of running
    Pic 3 cruisin the back roads
    Pic 4 coasting down a long grade

    If anyone cares to comment on the pics it would be appreciated.

    2001 Prius- purchased 2+ years ago- DOA
    Put a used hv batt out of a wreck and have put on 75000km bringing it up to 345,000km and was maintaining 4.7l/100 until last week- I want to get to 500k

    thanks for any help,
    Gord

    Did you run a health check to get the DTCs? If the TOD appeared codes should be stored.

    All module voltages look acceptable so maybe you have a P3006 which is a common
    code for Gen 1 batteries.

    Read the codes and get back to us.

    It popped the P3006- my son had cleared it when he read it with his scan tool
    Others
    P0171
    P3190
    P3101
    P3140 - I had the service plug out
    C1259 - I had the service plug out

    Would engine codes that result in low power pull the hv batt down when under load?

    thanks, Gord

    I would assume so because the ICE must be capable of charging the HV battery to an adequate level while you're driving. Hence the P3006 code.

    The other codes are indicating there's something wrong with the ICE - you will need to troubleshoot each one (obviously) until you find the root cause. Best of luck to you with this, Gord.
