    These are new codes since last night and all the days prior to this it was giving me the C0205 which is the front left wheel sensor now that's not showing up

    Have you heard the buzzer sound this whole time, or is that something new?

    The buzzer usually indicates low brake fluid pressure. Was anything done in between that you think might have caused this new problem? There is a button in Techstream to erase codes. The one in health check erases all at the same time or you can clear one ECU at a time while in the screen for each ECU. Keep in mind ABS codes usually clear themselves when you fix the problem and hit the road.

    That's interesting you saying that the about the brake fluid could cause that I guess I need to somehow figure out how to check the brake fluid that's a new one

    And that screeching buzzer sound it always comes on when I get the brake light the brake light in the Boeser sound almost always comes on within a couple of minutes when the ABS light comes on

    Nothing ever happened is that the day a week ago I took it in to get the windows tinted and before I could even get the car home in my driveway all the Christmas lights went off and this is all been happening ever since but I did replace the front left wheel sensor

    I know in the VCI tool I have cleared all the DTC codes and then within a day it all starts all over again

    Brake fluid pressure, not level.

    I just went into the system check through the MFD screen and my battery is 12.9v

    This is after my car has it for 45 minutes and I completely tried to drain it leave in the headlights on for a bit


    I am reading this is normal for ACC mode right ?

    B1421 is normal. The other could have been a result of testing the battery. Now that they're all cleared, it's time to hit the road and see what comes back.
