    The light will be on when the car is started, but my brake system has no problem at all, and the brake fluid is sufficient. OBD can't scan the code. Does anyone have the same problem?THX

    If the scanner you have can't show you the code(s) responsible for the ((!)) brake warning, you can do this:

    Blink (a/k/a Flash) Codes – How to. | PriusChat

    However, that doesn't work for the code(s) responsible for the triangle light. For that, you simply need a scanner that can read those. We have a review thread listing a bunch of options and which ones can and can't show you the codes you need:

    The brake system can and does set certain codes that only mean "hey, you need to look at the hybrid system codes", so if you do blink out the brake codes and they turn out to be only those, then that just underscores your need for a scanner that can show you the others.
