Official summary
Some 2021 F-150/Explorer/Aviator/Police Interceptor vehicles may exhibit a flashing powertrain malfunction (wrench) indicator while in transport mode with diagnostic trouble code (DTC) P112A stored in the powertrain control module (PCM). This may be due to excessive engine starts while the vehicle is in transport mode. To correct the condition, deactivate transport mode. Refer to Workshop Manual (WSM), Section 419-10 > General Procedures. Cycle the ignition to RUN. If the concern still exists, perform normal diagnostics in the Powertrain Control/Emissions Diagnosis (PC/ED) Manual.
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.
