    Popped P0626 tonight right after I left work. Only thing I can find online is that is has to do with the alternator/charging circuit(generic code). But nothing specific to Fiat. Can't get her to the studio till Monday. I tried to clear the code using my Ultraguage and the evic says "ESC not available...see handbook". Shut it off,tried again. Now evic says "hill start not available...see handbook"

    Pulling the the connectors off the ECU cleared everything up but, she pops P0626 within a minute or two after start up every time.

    Current mileage is 30126 miles.

    P0626-00-GENERATOR FIELD CONTROL CIRCUIT HIGH


    Theory of Operation
    There are two lines of communication between the Powertrain Control Module (PCM) and Generator. Based on sensed battery voltage, the PCM commands the Generator to charge the batteries to a desired voltage. The max voltage the PCM will command the Generator to charge is 14.75 Volts. The PCM then receives feedback from the alternator on the voltage level it is charging the batteries through a sense line. The PCM will not light a MIL lamp for this fault.

    When Monitored:
    When the engine is running.
    Set Condition:
    The PCM detects that the Generator Field Control circuit is open or shorted to voltage. Two trip fault.

    Possible Causes
    GENERATOR FIELD CONTROL CIRCUIT SHORTED TO VOLTAGE
    GENERATOR FIELD CONTROL CIRCUIT OPEN/HIGH RESISTANCE
    GENERATOR
    POWERTRAIN CONTROL MODULE (PCM)

    Studio cleared the code,found nothing wrong. As soon as I started her up to leave the studio, she popped the cel again. Same code,P0626. So now I have to take her back next Monday when they can give me a loaner since they feel its going to take a while to track down the issue. I'm hoping its just a bad cell in the battery or possibly too much current being drawn by the starter caused by a loose connection.
    My money is on the starter since it only pops the code at start up!
    I'll post more info once the studio gets this resolved.

    Update:
    Studio had the car for a week. Determined the wiring harness to the alternator was bad and so the replaced it. No more cel and everything seems fine so far!

    Mine popped a CEL on start up this morning. Oil level is fine, and everything else seems normal. No limp mode or anything. I am hoping that the system will eventually just clear the CEL after a few cycles. I don't have a reader. About 20k ago, I got a generic check engine light. The dealer said it was evap related, and they re-set it. Maybe it is the same thing again. Is there any possible benefit in disconnecting and re-connecting the battery? Thanks

    The better option would be spend abut $10 on an OBDII bluetooth reader and another $4.95 for the Torque Android app, (free version may work but I bought it) and then you can read the codes. Pulling the battery connection will clear the CEL but obviously that doesn't resolve whatever caused it.


    This is what I use and it works fine for me.

    OBDII reader I use: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
    (low profile was ideal with smaller car but I don't leave it in the car all the time, just wanted something small in the event I need to get in and out of the car).
    Torque app: https://play.google.com/store/apps/d...g.prowl.torque

    Thanks a lot Tweak. Do you happen to know if there is a variant that's compatible with Apple O/S?

    Whatever you do, don't buy an adapter from DASE Electronics LLC. Bought 2 and only got 1. They have an 18% positive / 81% negative feedback this past month. Really bad problems.

    Thomas,

    Your check engine light can come on for a number of reasons. Simple things such as a loose gas cap or poor fuel quality can cause the light to come on and can often disappear after several drive cycles.

    If the light remains on, a trip to your Studio can help to locate any store codes that may have been set. If the light begins to flash, it's recommended immediate service takes place.
