  Hold the connector, check connecting condition and locking efficiency.
2. When the connector is disconnected:
  Check missed terminal, crimped terminal or broken core wire by slightly pulling the wire harness.
  
  Visually check for rust, contamination, deformation and bend.
3. Check terminal tightening condition:
  Insert a spare male terminal into a female terminal, and then check terminal tightening conditions.
4. Pull lightly on individual wires to ensure that each wire is secured in the terminal.
