Some 2019-2020 Edge/Nautilus vehicles may exhibit an inoperative power liftgate with diagnostic trouble code (DTC) B144F:79 stored in the rear gate trunk module (RGTM). This may be due to the calibration of the RGTM. To resolve the concern, reprogram the RGTM using the latest software level of the appropriate Ford diagnostic scan tool. For claiming use causal part number 14B291 and Section 10 of the Service Labor Time Standards (SLTS) Manual. Do not replace the power strut unless DTC B144F remains after reprograming the RGTM.
