    5. Cycle the ignition switch.
      WARNING:

      To avoid possible serious or fatal injury, check brake capability is available before road testing.

    6. Test drive the vehicle by turning the vehicle left or right in a curving manner at a velocity between 10 and 20 km/hr (6 and 12 m.p.h.).
    7. Park the vehicle.
    8. With the scan tool, read ABS DTCs.
