Summary

This article supersedes TSB 23-2426 to update the list of modules needing a software update in the Service Procedure. Some 2023 F-Super Duty chassis cab vehicles equipped with a 6.7L engine may exhibit an engine coolant temperature gauge falsely reading at the high end of the normal range while towing in high ambient temperatures with no diagnostic trouble codes (DTC) stored in the powertrain control module (PCM) or warning messages present in the instrument panel cluster (IPC). This may be due to the software in the IPC. To correct the condition, follow the Service Procedure to reprogram the IPC. Note: Some vehicles built on or before 28-Feb-2023 may have TSB 23-2426 performed previously, but no IPC software update was available at that time. 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 center display 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 thesymptoms are no longer present, this article may not apply.

Owners of these vehicles have filed 28 complaints in the electrical category.
