Some 2015-2017 F-150 vehicles may exhibit intermittent and/or inoperative A/C, radio, and/or power window switch control with multiple illuminated warning indicators and/or diagnostic trouble codes (DTCs) U0140, U0155, U0253, U0401, and/or U0452 stored in the front controls interface module (FCIM). This may be caused by excessive network traffic on the controller area network (CAN) Bus causing the FCIM to lock up. Before replacing the FCIM, complete a battery reset, clear all DTCs and run a FCIM self-test. If the issue is still present, follow normal diagnosis. For claiming, use causal part 18842 and applicable labor operations in section 10 of the service labor time standards (SLTS) manual.
