Model:
Ford Engine: 3.5L PowerBoost
2023 F-150
Markets: North American markets only
Issue: Some 2023 F-150 vehicles equipped with a 3.5L PowerBoost engine may exhibit a Trailer Brake System
Fault See Manual message in the IPC and/or DTC U0140:87, U0143:87, and/or U0444:82 stored in the TRM. These
symptoms can occur without a trailer connected to the vehicle. This may be due to the software level of the GWM. To
correct the condition, follow the Service Procedure to reprogram the GWM software using the latest software version
of the FDRS scan tool.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
+ 2023 F-150
+ Equipped with a 3.5L PowerBoost engine
+ DTCs U0140:87, U0143:87, and/or U0444:82 stored in the TRM

Service Procedure

NOTE: Ask the customer to bring their spare key fob to assist in the FDRS programming. 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. It is recommended to connect to the
internet with an ethernet cable and use a USB 3.2 capable flash drive when performing software updates.

1. Start an FDRS session and navigate to Toolbox tab > Datalogger > BCM and select the BATT_SOC PID. Verify the
PID reads 50% or higher. 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.

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. It is not necessary to perform a BMS

reset unless the battery is replaced.
(1). If the battery is unable to achieve a 50% SOC then a new battery may be required. Use the Rotunda GRX-
3590 or DCA-8000 testers to verify if replacement is required. If the battery is replaced, fully charge the new
battery, then 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 state of
charge 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 GWM, TCU, or APIM?

(1). Yes - proceed to Step 4.
(2). No - this article does not apply. Refer to WSM, Section 415-00.

4, Perform the Module Software Updating Procedures outlined below for the GWM, TCU, and APIM. Perform a
network test after each software update using the latest software level of the FDRS scan tool. This refreshes the
list of modules that have available software updates based current module software levels. Continue performing
software updates to the GWM, TCU, and APIM 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

The following instructions apply when performing a software update on any of the following modules:

*ARIM

NOTE: A 32GB or larger USB flash drive is required for 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. Download and run the application
for desired module. Follow all on-screen instructions carefully.

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 PC, turn the vehicle to KOER.
Connect the USB flash drive to the media hub to install the software update. The update starts automatically and
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 with software update.
4. When the vehicle's center display screen prompts to restart the vehicle:

(1). Turn the vehicle OFF.

(2). Wait 10 minutes.

(3). Turn the vehicle to KOER.

(4). Leave the USB flash drive inserted into the vehicle, until the vehicle's center display screen states

programming successful.
NOTE: It may take up to 5 minutes before the vehicle's center display screen displays the Update Successful
pop-up. After 5 minutes if Successful pop-up is not shown on the center display screen, remove the USB
flash drive and select YES on the FDRS Was The USB Update Successful prompt ( FDRS verifies if the
module software update was successfully installed on the module).
5. Continue following the FDRS prompts to complete all GWM/ T.CU/ APIM software updates.
