Some 2019-2020 Ranger vehicles may exhibit random Trailer Connected/Disconnected messages in the instrument panel cluster (IPC) message center when no trailer is connected. This may be caused by corrosion and/or moisture in C4098 (4-pin trailer tow connector), C4099(4/7 way trailer tow connector), and/or inline C405. To correct the condition, follow the Service Procedure steps to inspect and repair the wiring and reprogram the trailer module (TRM).
