How do you reset ABS light & yellow ((!)) with Mini VCI and techstream

Just ran text stream on it again and here are my codes

U0129
U0121 - Lost communication with ABS
b1421
c1300

 

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 ?

 

Okay thanks how do I get the brake fluid pressure checked this is something I need to look into that sounds like a really good option that you are giving me

 

This is very strange I just ran the health check again and now there is only one code

 

$10 says it's B1421!

 

Oh new. Clare's it !! Running it

Stan!

 

Dang it now I can't get my codes back it's cleared them I guarantee you it will come back as soon as I take it for a drive and I'm going to be doing that shortly

 

Hey the 1421 was one of them!! Is that the brake pressure? Oh my god I owe $$!! If this saves me as I was getting ready to call the Steeler ship tomorrow ugh !

 

1421 is basically nothing

 

How do I get brake pressure checded

 

What is the u codes above mean? And the 1300?

 

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.

 

Ok going NOW !!

 

Haven't even left the garage just turned it on ABS BSC and brake light on no red triangle though

 

No screeching buzzer either
