Official summary
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).
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
