    Check Charging System

    Hi all,

    New to the forum. I just bought a second hand 2014 Civic and its been great except one thing.
    Every-time I start the car, 10 seconds later, "Check Charging System" pops up and battery light come on in the dash.

    To my understanding, the system had an ELD which controls when the alternator kicks in and when it does not.
    Whenever I start the car, I get a reading in the 14v's, regardless of what accessories are on, headlights, etc.

    I have changed the battery. I have changed the negative terminal battery sensor. I have changed the ELD (in hood fuse box). I have checked all other fuses.

    Message still comes on every time.

    Any ideas?
    Thanks for your input.

    Absolutely no mods at all. It is a 2014 Civic LX.

    In light of the parts you have already replaced.
    And a healthy Honda charging system should not see 14v unless the system is loaded.
    Next likely thing would be the voltage regulator.

    I acttually put in a new alternator from O'Reillys yesterday. I get some fluctuation, between 13.5 - 14.6V at idle, all consumers off. I believe the voltage regulator is built in the alternator, right?
    The Check Charging System light remains on.

    Correct.
    I do not know the quality of an o'reilly alternator; but many aftermarket parts do not play well with some Honda systems...
    Sounds like you will need to consult the service manual for further diagnosis.

    Thank your for your continuous input and help. Where could I gain access to a manual? Would that be a similar/same manual that honda techs use?

    Yes, having the voltmeter connected it is on 14.5-14-6V constantly as soon as the vehicle is started.

    I was able to follow the procedure in one of the links and perform a self-check but it does not give me anything conclusive. I get the following message:
    F-CAN --- ERROR
    B-CAN --- OK
    UART --- OK
