    1. While the connector is connected: Hold the connector, and check connecting condition and locking efficiency.
    2. When the connector is disconnected: Check for missing terminal, crimped terminal or broken core wire by lightly pulling the wire harness. Visually check for rust, contamination, deformation and bending.
    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.
