    I changed out the hybrid drive battery in my 2008 Prius. We hooked everything up and now the car seems to be in limp mode. Will not crank, will not go into gear, and all warning lights are now on. Any advice would be great? Thank you in advance!

    Check the orange traction battery interlock. When you install it, you pivot the lever 90 degrees. Then slide it down to lock in place.

    What condition was the car before you changed the high voltage battery pack? Did you have any error codes?
    What kind of work did you or someone else do on the pack you put back into the car? Also do you have error codes from the car's current situation, or are those error codes left over from before you changed pack? As in have you read & cleared the codes via a code reader or disconnecting the 12v battery for a few minutes?

    Lastly, there's more than 100 connections that have to be made perfectly to get a battery pack working... Have you triple-checked all of them?
