Step Two: Wall Sensors

Use a thick, flat, and white surface to imitate a wall and drag it around Bob’s bumper.

The third battery bar, second battery bar, first battery bar, and the words DIRTY and

ERROR should light up one-by-one on Bob’s screen as you move your imitation wall

around his bumper.

You may now move on to the next step of the checkup test. Do not press any additional

buttons.
