This connector is not sealed from the inside of the vehicle and water may enter the connector causing the terminals to become corroded. Also, the female terminals of the connector may have become spread apart causing an intermittent poor connection. Correction Important: • Inspect the terminals at connector C305 for corrosion or spreading before replacing the fuel module or resistor card kit. Terminals can be accessed from underneath the vehicle. • Do not attempt to repair any spread female terminals as this will result in a return repair. The female terminal must be replaced. • If the terminals show signs of corrosion, determine the source of the water leak first and repair the water leak before repairing the terminals in connector C305. Refer to Corporate Service Bulletin Number 01-01-38-009A to determine a potential source for water in the vehicle interior. Repair any corroded and/or spread female terminals in connector C305. Refer to Repairing Connector Terminals in the Wiring Systems sub-section of the appropriate service information.
