    I have a 2007 Toyota Prius over 130K miles. I received a red triangle light on while driving yesterday along with check engine light on. I checked engine oil and it looked fine. Then I got the codes checked scanned by xpress oil change which returned a bunch of codes:

    P3000: Battery control system
    P3102: Transmission control ECU
    C2300: Actuator System Malfunction
    P0A7F: Hybrid Battery Pack Deterioration
    B1421: Solar Sensor Circuit (passenger Side)

    It does look like the hybrid battery seems to be deteriorating. Could the other codes be related to that or they are different issues. What are my options.
    Thanks.

    As you can tell, having the subcode / detail code (aka INF) for the above DTC P3000 might be helpful is tracking down the issue.

    Do you have a DIY mechanical attitude, or would you be relying on someone else to sort out the above issues for you?
