Circuit/System Verification

  1. Ignition ON, verify the scan tool can communicate with right side object sensor.
    • If the scan tool can not communicate with the right side object sensor, refer to Right Side Object Sensor Malfunction in Circuit/System Testing .
  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 in Circuit/System Testing .
  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.
    • If both indicators do not briefly illuminate during the system self test, the side blind zone alert system has been disabled. Refer to Diagnostic Aids .
    • If only one indicator does not briefly illuminate during the self test, refer to Side Object Indicator Malfunction in Circuit/System Testing .
