  3. INSPECT OUTER REAR VIEW MIRROR ASSY LH OR RH (RETRACTABLE MIRROR MOTOR) 
    1. Disconnect the R14 or R15 mirror connector.
    2. Apply battery voltage and check the operation of the retractable mirror.
      NOTE:
      • Disconnect and reconnect the battery once between each mirror position check.
      • The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.
