Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.P3000 code indicates a problem with the high voltage battery. Check the battery voltage readings using the scanner to see if they are all low or if one or more might be low on voltage. The common cause for this code usually means the High Voltage (HV) Battery has failed.
