    I charged the almost dead 12v with a slow charger and it is fine now. but immediately after charging the brake system light came on. i believe brakes are just fine, and want to reset the light and see if it will ever give again.
    anyone knows how to do that?

    Disconnect the 12 V battery for a few minutes.
    If that doesn't work, see a dealer or independent shop.

    That light also indicates that the parking brake is ON, in which case it can be "reset" by putting the brake OFF. :)

    No, the light I mean is not the parking brake light.
    It is the yellow color exclamation mark inside a circle and circle inside parenthesis.

    You can reset the skid control ECU by using a jumper on pins 4 and 13 of the OBD-II socket. Do a search for the procedure and make sure you know for sure which pin is which before you attempt this.
