Some 2021-2022 F-150 vehicles equipped with a 3.5L PowerBoost engine may exhibit an illuminated powertrain malfunction (wrench) indicator with DTC P2C44:00 stored in the powertrain control module (PCM). This may be due to an issue with ground circuit GD132 or the auxiliary battery isolator. Perform Pinpoint Test I in Workshop Manual (WSM), Section 303-06D and make sure the integrity of GD132 is carefully inspected and tested with the inclusion of G102, C146 and C1989C. Then perform the Auxiliary Battery Conditions(s) Test in WSM, Section 414-01, Pinpoint Test B. If no issues are found in Pinpoint Test I, GD132 and the auxiliary battery condition test passes, replace the auxiliary battery isolator per WSM, Section 414-01. For claiming, use causal part 14526 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB 22-21542022-05-12. Service bulletin. ELECTRICAL SYSTEM:INSTRUMENT PANEL:FUEL GAUGE:FUEL LEVEL FLOAT/SENSOR/SENDING UNIT; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. This article supersedes TSB 22-2050 to update the Issue and Action. Some 2021 F-150 vehicles equipped with a low-level instrument panel cluster (IPC) which has a 4.2-inch display may experience erratic operation of the Eco-Coach feature, or this feature may be missing and/or the transmission temperature gauge reading inaccurate. This may be due to software parameters in the IPC. To correct the condition, follow the Service Procedure to reprogram the IPC. NOTE: The IPC software update that addresses the symptom listed in this bulletin may have been sent via Ford Power-Up software updates delivered over-the-air (OTA) to connected vehicles that have automatic updates enabled through the SYNC 4 screen. Enter the vehicle identification number (VIN) in Professional Technician System (PTS) and check the OTA Dashboard under the Connected Vehicle tab for OTA update history. If an update to the IPC has successfully completed recently and the customer is reporting the symptoms are no longer present, this article may not apply.
TSB 22-21512022-04-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:SOFTWARE. Some 2021 F-150 vehicles equipped with a 3.5L PowerBoost engine and built on or before 23-Apr-2021 may experience an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300, P0301-P0306, P0316, P050E, P1674, P0454 and/or P2451 stored in the powertrain control module (PCM). This may be due to various software parameters within the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.
SSM 507002022-04-20. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2021 F-150 vehicles equipped with a 5.0L engine and built on or before 9-Apr-2021 may exhibit a no crank/no start with no powertrain control module (PCM) communication condition if the oil life is at or less than 20%. This may be due to various parameters within the PCM. To restore PCM communication and correct the condition, follow the service procedure in Customer Satisfaction Program 21B37.
SSM 506142022-03-22. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); POWER TRAIN; ELECTRICAL SYSTEM. Some 2021-2022 F-150 vehicles equipped with a 3.5L PowerBoost engine and built on or before 31-Jan-2021 may experience an illuminated malfunction indicator lamp (MIL) with diagnostics trouble codes (DTCs) P04F0 And/Or P04EE stored in the PCM. This may be due to the fuel tank pressure (FTP) sensor becoming unseated from it's mount on the evaporative (EVAP) tube that connects to the top of the fuel pump and sender unit, causing an EVAP system leak near the top of the fuel tank. If the sensor is found to be unseated, resecure the sensor by pressing the sensor down vertically and retest. If the concern is resolved, the 9D683 assembly needs to be replaced due to the sensor retainers becoming weak. Refer to Workshop Manual, Section 303-13D. For claiming, use causal part 9D683 and applicable labor operations in Section 09 of the Service Labor Time Standards (SLTS) Manual.
