Is the resistance as specified?

YES -Faulty rear safing sensor or poor connection at the floor wire harness 4P
connector and the rear safing sensor. Check the connection between the
connector and the rear safing sensor. If the connection is OK, replace the rear
safing sensor (see REAR SAFING SENSOR REPLACEMENT).

NO -Open in the floor wire harness; replace the floor wire harness.
