    Howdy PC, what is this device here? And would it be possible to cause the P0A80 code after 100 miles?


    PART 2:
    I'll start by saying I'm very familiar with gen2 batteries and have successfully repaired about 50 of them now.

    This is my first gen3 job (2012 prius V)

    Battery that came out seemed to have no issue besides a variance in modules about .3 volts. Busbars, wires and plugs all look good.

    Battery I put in the car in the same good condition but with balanced modules all between 8.09-8.13 volts. I DID NOT REALIZE THIS BATTERY WAS MISSING THE BROWN DEVICE SHOWN.

    Customer got P0A80 code at about 100 miles, is it possibly due to this device missing? What other issues can occur that might be common to gen3 but not gen2? 1555516395248.jpeg

    Might be ELECTRICAL KEY OSCILLATOR? One of several, around the car?

    Also I tried to punch up the number on it a bit, but not sure that's a part number:

    If you lean back it's easier to read; I make it: PA66-GF33. Maybe.

    @Elektroingenieur is good at this stuff.

    I tried a Google and Ebay search on both numbers which are on it and nothing came up. But that does make sense considering it's close to the trunk.

    This model’s version of the last mystery part, I think. @Mendel Leisk has it right—it’s an antenna for the Smart Key system. See parts catalog Figure 84-20, Wireless Door Lock, item ⑤, part number 899A0-47010, known to its friends as the No. 2 Indoor Electrical Key Antenna Assembly.
    I suppose there’s a small chance of an electromagnetic compatibility issue of some kind between the unterminated wiring for the missing antenna and the battery smart unit, but I doubt it; the systems are otherwise unrelated. P0A80 in a vehicle with a known-faulty HV battery is probably just P0A80.

    That’s P0A80, by the way; SAE J2012 (PDF) says DTC characters 2–5 are hexadecimal digits.
    It isn’t; the > and < signs tell us that it’s an identification code for the material, and PA66-GF33 means the plastic cover consists of polyamide 6,6, reinforced with 33% (by mass) glass fiber.

    Toyota and its suppliers mark many plastic parts with such codes, so they can be sorted for recycling when the vehicle is dismantled. The codes are defined in the ISO 11469, ISO 1043-1, and ISO 1043-2 standards. I’ve linked before to an HP document with more information (PDF); the same codes are used in many industries.
