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.

Examples of proper and improper wire routing in a harness
Before disconnecting the connector, check for improper wire routing into the connector. Wires that are improperly routed into a connector can deform the seal bore allowing moisture or other forms of contamination to enter the connector.
For intermittent conditions, disconnecting and reconnecting a connector may temporarily solve a problem. However, the indication is that there could be a problem in the connector. A problem in the connector or the harness close to the connector that has been temporarily resolved will most likely reoccur. If this situation occurs, check for the following conditions:
Loose terminals, bent terminals, or improperly crimped terminals.
Perform the 45 N (10 lb) pull test on each wire. Pull on the wires that are entering the connector in order to determine if all terminals are properly locked in the connector body. The pull test can also determine if a wire is broken at the terminal crimp.
Examine the insulation on the wires that are entering the connector. Look for damage to the insulation in the form of abrasions, nicks, or cuts.
For terminal replacement or wire repair, use the 1U-5804 Crimp Tool (12-GA TO 18-GA) to replace the terminal. Replace any damaged connectors as required.
Ensure that the connectors lock properly to the mating connector when connected. After locking the connectors, ensure that the mating connectors cannot be pulled apart.
