Multiple DIC Messages and Loss of Low Speed LAN Communication

Some 2016-2019 Volt models may experience a no start condition, multiple Driver Information Center (DIC) messages, and/or a loss of low speed Local Area Network (LAN) communication. If any of these conditions are present, there may be possible water intrusion in the X450 connector located in the left rear fascia area. (Fig. 22)

Check the X450 connector — where the rear lamp harness plugs into the body harness — for any signs of moisture damage. (Fig. 23) If any damage is found, repair the circuits as needed following the appropriate Service Information for terminal replacement or connector with leads assembly replacement.
