SSM 50293 2019-2021 Ford Ranger – Lack Of A/C Cooling Performance And/Or A/C Compressor Engagement With Remote Start Function – Built On Or Before 01-Sep-2021
Some 2019-2021 Ford Ranger vehicles built on or before 01-Sep-2021 may experience a lack of air conditioning (A/C) cooling performance condition and/or an A/C compressor engagement concern when using the remote start function (if equipped). This may be due to the software within the front controls interface module (FCIM). To correct the condition, reprogram the FCIM using the latest software level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 19980 and applicable labor operations in Section 12651D4 of the Service Labor Time Standards (SLTS) Manual. After FCIM programing, check for A/C operation and correct as necessary.
