SSM 505492022-03-08. Service bulletin. EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2018-2020 F-150, 2017-2022 F-Super Duty and 2016-2022 F-650/F-750 vehicles equipped with a diesel engine may exhibit diagnostic trouble code (DTC) P0000 stored in the powertrain control module (PCM) after an on-demand self test. This DTC is due to a processing error in the PCM as a result of on-demand self testing. P0000 is an invalid DTC that will not illuminate the malfunction indicator lamp (MIL) and no repairs should be performed.
SSM 503752021-12-27. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM); ELECTRICAL SYSTEM:SOFTWARE. Some 2016-2021 Ford and Lincoln vehicles equipped with SYNC 3 may exhibit a condition where the navigation voice prompts are inoperative after a SYNC map update. This may be due to an incomplete installation of the SYNC map software. If possible, using the original USB that installed the update, reperform the update and verify the navigation voice prompts have returned. Multiple reboots are expected when this update is being performed. Verify the Installation Is Complete message displays in the touch screen. If the original USB is not available, go to website https://syncnavigation.com/ford/home or https://syncnavigation.com/lincoln/home to download the files once more for the affected vehicle. For further map update support, reference the FAQ section on these websites.
SSM 503462021-12-26. Service bulletin. EQUIPMENT:ELECTRICAL. Some 2018-2021 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number (ESN) displayed or DTCs U2100 and/or B156D in the telematics control unit (TCU). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version (if applicable) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14G229 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 502612021-12-07. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:CLUTCHES/BANDS:ACTUATORS/SOLENOIDS; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2021-2022 F-Super Duty vehicles may exhibit harsh or delayed engagement/shift concerns. Most concerns may be addressed with the PCM/TCM Transmission Accelerated Main Control Break In Routine. Refer to Workshop Manual (WSM), Section 307-01, DTC Chart and/or Diagnosis By Symptom to identify the clutch(s) to be cycled. This routine cycles the shift solenoids and clutch control valves to remove contamination that may be sticking the valves and must be performed along with an adaptive learning drive cycle before attempting internal service. Although this routine was originally developed for low mileage vehicles, it has proven effective for resolving many shift and engagement symptoms across the life of the vehicle. For claiming, use causal part 7A100 and applicable labor operations in Section 7 of the Service Labor Time Standards Manual.
TSB 21-24202021-12-01. Service bulletin. POWER TRAIN; EQUIPMENT.
