Service bulletin SSM 52309
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some 2024 F-150 vehicles may set diagnostic trouble code (DTC) P0534:00 in the powertrain control module (PCM) when a diagnostic self-test is performed. This may be due to the PCM responding to large changes in ambient temperatures from warm to below freezing when the vehicle has less than 62 miles (100 km) and still in a rapid learn mode for the ambient air temperature logic. The rapid update to the temperature can result in the vehicle setting this DTC. DTC P0534:00 does not affect vehicle drivability and has no effect on vehicle operation. No additional diagnostics or service is required for this condition at this time. DTC P0534:00 is a background diagnostic code for service only and does not illuminate the malfunction indicator lamp (MIL), powertrain malfunction indicator (wrench), or provide any indication to the vehicle operator. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q2 2024. Replacement or reprogramming of the PCM will not resolve this condition. Monitor OASIS for additional informati

| SSM 52318 | 2024-03-20. Service bulletin. Some 2024 F-150 vehicles equipped with a 3.5L PowerBoost may set incorrect cylinder misfire DTCs while the CSER monitor is active. The CSER monitor runs for approximately 3 minutes after a cold soak start-up. If a misfire occurs while the CSER monitor is running, the powertrain control module (PCM) software strategy may set an incorrect cylinder misfire code. Prior to a repair attempt, allow the vehicle to run for at least 3 minutes and verify any individual cylinder misfire codes by performing a Power Balance Test using the Ford Diagnostic and Repair System (FDRS) scan tool. Engineering is currently working on a solution for this condition and will be released via Ford Power-Up software updates delivered over-the-air (OTA) expected in Q3 2024. Software will update automatically if vehicle connectivity is enabled in the vehicle's settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update in Q3 2024. Monitor OASIS for additional information. |
