Connector Inspection Procedure: Notes
- Handling of Connector
- Turn on all electrical systems to simulate an excessive electrical load. (Radios, fans, lights, rear window defogger, etc.)
- When removing the connector with a latch, press or pull locking lever.
- Listen for a click when locking connectors. This sound indicates that they are securely locked.
- Check waterproof connect or terminals from the connector side. Waterproof connectors cannot be accessed from harness side.NOTE:
- Use a fine wire to prevent damaging the terminal.
- Do not damage the terminal when inserting the tester lead.
- Turn on all electrical systems to simulate an excessive electrical load. (Radios, fans, lights, rear window defogger, etc.)
- Checking Point for Connector
- While the connector is connected:
Hold the connector, and check connecting condition and locking efficiency.
- 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.
- 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.
- While the connector is connected:
- Connector Terminal Repairing Method
- 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.
- Clean the contact points using air gun and/or shop rag.
