Inspection of the connector housings, the pins, and the sockets on the mating connectors may lead to a quick resolution of a specific problem.The following table lists the tools and the repair kits that will be useful for removal and repair of connector contacts and wires.

Verify that a diagnostic code is active or an intermittent problem is occurring before disconnecting the harness connectors.
When a connector is disconnected and reconnected, the chance for increased wear, damage to the connector, or contamination of the connector increases.
When possible, turn off the key start switch before disconnecting the harness connectors.
Disconnecting connectors with the power off avoids the possibility of introducing voltage spikes into the system.
When troubleshooting a circuit, a procedure may require the control voltage to be turned ON with a harness connector disconnected. Always inspect the connector before turning ON the control power. Ensure that the connector is clean, dry, and in good condition.
The recommended practice is to turn OFF the key start switch before reconnecting of the connector.
