TECHNICAL SERVICE BULLETIN
6.7L - Engine Coolant Temperature Gauge Falsely Reads High

24-2210
08 July 2024

This bulletin supersedes 23-2426. Reason for update: update the list of modules needing a software update in the
Service Procedure
Model:
Ford
2023 F-Super Duty

Chassis cab
Engine: 6.7L diesel

Markets: North American markets only
Issue: 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 DTC stored in the PCM or warning messages present in the 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 an
OTA update to connected vehicles that have automatic updates enabled through the center display screen.
Enter the VIN in 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.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
• 2023 F-Super Duty chassis cab
• 6.7L diesel engine
• Engine coolant temperature gauge falsely reads at the high end of normal while towing
• No DTCs or overheat warning messages present

2023 F-350

Condition Code: 04

Service Procedure
NOTE: The time required to complete this procedure will vary depending on several factors including the
number of module software updates required, available internet bandwidth, USB flash drive variability, and
the potential that CAN flashing (software update via the DLC with FDRS) may be required. Connect to the
internet with an ethernet cable, use a USB 3.2 Gen 2 or higher flash drive. When performing USB software
updates, using high speed USB ports on the laptop is recommended for faster file transfer.
1. Start an FDRS session and navigate to Toolbox tab > Datalogger > body control module (BCM) and select the
BATT_SOC PID. Verify the PID reads 50% or higher.
NOTE: Connecting the battery charger negative clamp directly to the battery negative terminal might result in
the SOC PID not immediately reflecting the improvement from charging.
(1). If SOC is less than 50%, charge the battery by attaching the battery charger's negative clamp to the engine or
chassis ground and not the negative battery terminal. Refer to WSM, Section 414-01.
(2). If the battery is unable to achieve a 50% SOC, use the Rotunda GRX-3590 or DCA-8000 testers to verify if
replacement is required.
• If the battery does not need to be replaced, disconnect the Rotunda charger and perform a BMS reset using
the FDRS scan tool.
• If the battery is replaced, fully charge the new battery, disconnect the Rotunda charger and perform a BMS
reset using the FDRS scan tool.
2. Reconnect the battery charger and set it to maintain a vehicle voltage of 12.6-13.6 volts. A low battery SOC while
performing a software update to any module may result in a repeat Restart Required message in the vehicle's
center display screen or a message on the FDRS saying "Part Number Validation Failed" or "DID Validation
Failed".
3. Are there any updates available for the IPC, GWM, APIM, TCU, BCM, PCM, TCM, or SOBDMC?
(1). Yes - proceed to Step 4.
(2). No - this article does not apply. Refer to WSM, Section 303-03.
4. Perform the Module Software Updating Procedure below for the IPC, GWM, APIM, TCU, BCM, PCM, TCM and
SOBDMC. Perform a network test after each software update using the latest software level of the FDRS scan tool.
This will refresh the list of modules that have available software updates based current module software levels.
Continue performing software updates until all available software updates for those modules are complete. If any
error conditions are experienced during programming, refer to WSM Section 418-01A > General Procedures >
Module Programming for the Error Condition Table.

Module Software Updating Procedure
NOTE: Depending on the current software level of the modules, all the following updates may not be
required.
The following instructions apply when performing a software update on any of the following modules:
• IPC
• GWM
• APIM
• TCU
• BCM
• PCM
• TCM
• SOBDMC
NOTE: If the next update is not showing available, perform a network test and recheck availability.

NOTE: A 32GB or larger USB flash drive is required for the GWM, TCU and APIM software updates. USB 3.2
or higher is recommended for faster file transfer.
Make sure the USB flash drive being used is formatted correctly. To see the available drives, hold down the Windows
icon keyboard key and press the E keyboard key. Right click on the USB flash drive and select Properties. If File
System under the General tab is not exFAT, the drive must be formatted.
To format the USB flash drive:
• Right click on the USB flash drive.
• Select Format, select exFAT for the File System.
• Select Default Allocation Size for the Allocation Unit Size.
De-selecting Quick Format is not necessary and results in a lengthier operation.
1. Using the FDRS, begin module programming by selecting the "SW Updates" tab. Follow all on-screen instructions
carefully. Perform the next available update.
2. When prompted, connect the USB flash drive to the FDRS.
3. When prompted by the FDRS, safely remove/eject the USB flash drive from the FDRS and connect it to the USB
media hub to install the software into the module. When the USB software update begins, the vehicle's center
display screen displays a message stating "Do Not Remove USB". The update may take 10 minutes or longer to
complete.
NOTE: It may take up to 5 minutes for the vehicle to recognize the USB flash drive.
4. When the pop-up stating "Restart Required" appears on the vehicle's center display screen:
(1). Turn the ignition off.
(2). Wait for 10 minutes.
(3). Restart the vehicle (KOER). The update is still in progress at this time.
NOTE: It may take up to 5 minutes before the vehicle's center display screen displays "Update Successful"
pop-up. After 5 minutes, if "Update Successful" pop-up is not shown on the vehicle's center display screen,
remove the USB and select yes on the FDRS prompt for "Was the USB Update Successful" ( FDRS verifies if
the module software update was successfully installed on the module).
5. Once the pop-up stating "Update Successful" appears in the vehicle's center display screen, select Close, remove
the USB flash drive from the USB media hub, and select Yes on FDRS indicating the update installed successfully.
This initiates the remaining automated configuration steps and reports the module software part numbers and
application software levels to the Ford online database. Failure to follow this step results in an inaccurate database
as well as omitted, improperly installed, or improperly configured applications (features) such as navigation (if
equipped). It is normal for the module to reset during this step.
