    I replaced the rear drum brakes, wheel cylinders, and bled the brakes. I discovered on drivers side, that no matter how much bleeding, the brake does not engage on the rear drivers side. While bleeding, I discovered very little pressure. The brake light, VSC, ABS, and ! lights remain lit while the cars on. Does this sound like a master cylinder or ABS failure? Can the autoenginuity scan this issue?

    Try getting the blink codes from the ABS system. You short pins 4 and 13 of DLC3, and watch the blinky lights on the dash:

    ABS, VSC Lights... Weird!! | PriusChat

    That will eliminate some guess work. Don't know about Autoenginuity, but the mini VCI does the brakes.

    If you tried bleeding the brakes the same as any other car that is the problem. As nh70 said you need the mini VCI and a laptop with Techstream software "comes with VCI" to do the job successfully.
