    So… I did a stupid thing. Feel free to yell at me for being an idiot but also please help me to fix this:

    2010 Prius. I replaced the clock spring and I was trying to calibrate the steering angle sensor as it shows to be -850 degrees off.

    So in me finagling the system I got to the ABS stuff and “reset the memory”

    Ever since I get the ABS/brake/circle with exclamation point on.

    I followed some tutorials on YouTube to see if I can reset. No result.

    Can someone point me to what is the correct procedure to reset these lights and ABS system?

    I currently have no ABS or regenerative braking and the brake feels stiff

    Please keep in mind there is nothing mechanically wrong with the braking system

    I have techstream version 16.xxx and can only run in offline mode

    Thanks

    I believe you need to set the linear valve offset. Clear the codes with your scanner after you read and write them down and see what comes back.

    We can be more help if you tell us why the warning lights are on. Then we know what to suggest to fix that.

    The easiest way to find out why is to use a scan tool that can show you those trouble codes, but if you don't have that, you can get the codes this way:

    Use Techstream to do a Health Check, and then post all the trouble codes listed as "current".
