Cause
These conditions may be caused by water leaking into the vehicle causing terminal corrosion at inline connector X 350. This connector is not sealed off
from the inside of the vehicle and if a leak is present, water may eventually enter the connector causing the terminals to become corroded.
Correction
1. Disconnect the separate fuel tank harness connectors that connect to the underside of the X 350 connector. For the location of X 350, refer to >
Power and Signal Distribution > Wiring Systems and Power Management > Component Locator > Master Electrical Component List > Code > X
