Summary
Some 2027 Expedition/Navigator vehicles equipped with power running boards may exhibit an intermittent condition where the power running boards are unable to deploy or retract with a "Power Running Board Fault" message in the instrument panel cluster (IPC). Diagnostic trouble codes (DTC) C1008:15 and/or C1009:15 may be stored in the driver seat module (DSM). DTC U0208 and/or U0244 may also be stored in various other modules. Other DSM functions may be affected such as heated/cooled/memory seats. This may be due to the software in the DSM. If the DSM does not respond during a network test, press the power seat adjustment switch then re-run the network test to see if DSM communication is restored. Engineering requires feedback for this action. Submit a Global Concern Report (GCR) indicating if DSM communication was restored after actuating the power seat adjustment switch, noting the DTCs present. To submit a report, click on the "Submit Global Concern Report (GCR)" link at the upper right of the Professional Technician System (PTS) Vehicle ID screen (vehicle identification number ÝVIN¨ requi
