Information:
Check Connectors for Moisture and Corrosion
Inspect all the harnesses. Ensure that the routing of the wiring harness allows the wires to enter the face of each connector at a perpendicular angle. Otherwise, the wire will deform the seal bore. The damaged seal will create a path for the entrance of moisture. Verify that the seals for the wires are sealing correctly. Ensure that the sealing plugs are in place. If any of the plugs are missing, replace the plug. Ensure that the plugs are inserted correctly into the connector.Disconnect the suspect connector and inspect the connector seal. Ensure that the seal is in good condition. If necessary, replace the connector.Thoroughly inspect the connectors for evidence of moisture entry.Note: Some minor seal abrasion on connector seals is normal. Minor seal abrasion will not allow the entry of moisture.If moisture or corrosion is evident in the connector, the source of the moisture entry must be found. The source of the moisture entry must be repaired. If the source of the moisture entry is not repaired, the fault will recur. Simply drying the connector will not fix the fault. Check the following items for the possible moisture entry path:
Missing seals
Incorrectly installed seals
Nicks in exposed insulation
Improperly mated connectorsMoisture can also travel to a connector through the inside of a wire. If moisture is found in a connector, thoroughly check the connector harness for damage. Also check other connectors that share the harness for moisture.Check the Wires for Damage to the Insulation
Carefully inspect each wire for signs of abrasion, nicks, and cuts.Inspect the wires for the following conditions:
Exposed insulation
Rubbing of a wire against the engine
Rubbing of a wire against a sharp pointCheck all of the fasteners for the harness and the ECM in order to verify that the harness is correctly secured. Also check all of the fasteners in order to verify that the harness is not compressed. Pull back the harness sleeves in
