I have a 2006 Prius with a HV Battery pack that was just purchased from a Toyota store. I installed the HV battery and the following codes came back: P3000 P0AC2 C1259 C1310 Any ideas where to start
Check all your plugs... Something is not completely connected. Start with Orange Safety plug, that's the main one people too often don't push down all the way.
P0AC2 is probably the one to look at and has the fortune cookie (© ChapmanF) text that says: Hybrid Battery Pack Current Sensor Circuit High. DESCRIPTION The battery current sensor, which is mounted on the negative cable side of the hybrid vehicle (HV) battery assembly, detects the amperage that flows into the HV battery. The battery current sensor inputs a voltage (which varies between 0 to 5 V in proportion to the amperage) into the IB terminal of the battery ECU. An output voltage of the battery current sensor below 2.5 V indicates that the HV battery assembly is being charged, and above 2.5 V indicates that the HV battery assembly is being discharged. The battery ECU determines the charging and discharging amperage of the HV battery assembly based on the signals that are input to its IB terminal and calculates the SOC (state of charge) of the HV battery through the estimation of the amperage. The full diagnostic for this code can be found in the repair manual. See here for more info on the options of how to access the repair manual.
I hereby place the use of "fortune cookie", for the near-useless short mnemonic titles of diagnostic trouble codes, into the public domain.
