    • If the scan tool can not communicate with the right side object sensor, refer to Right Side Object Sensor Malfunction
  2. Verify the scan tool can communicate with left side object sensor.
    • If the scan tool can not communicate with the left side object sensor, refer to Left Side Object Sensor Malfunction
  3. Ignition ON, verify that the side blind zone alert system indicators located in the outside rearview mirrors briefly turn ON and then turn OFF during the system self test.
