      NOTE:
      • Use a fine wire to prevent damage to the terminal.
      • Do not damage the terminal when inserting the tester lead.
  2. Checking Point for Connector
    1. While the connector is connected: 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.
