    • Listen for a click when locking connectors. This sound indicates that they are securely locked.

    • When a tester is used to check for continuity, or to measure voltage, always insert tester probe from wire harness side.

      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
    • While the connector is connected:

      Hold the connector, check connecting condition and locking efficiency.

    • 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.

    • Check terminal tightening condition:

      Insert a spare male terminal into a female terminal, and then check terminal tightening conditions.

    • Pull lightly on individual wires to ensure that each wire is secured in the terminal.

  3. Repair Method of Connector Terminal
    • Clean the contact points using air gun and/or shop rag.
      NOTE:
      • Never use sand paper when polishing the contact points, otherwise the contact point may be damaged.
    • In case of abnormal contact pressure, replace the female terminal.
