Intermittent No Start And Stop Safely Now Message Displayed And/Or 04 October
DTCs U0293 And/Or P1A43 In The Battery Energy Control Module (BECM)
Model:
Ford FHEV
2023 F-150
Issue: Some 2023 F-150 fully hybrid electric vehicles (FHEVs) may exhibit an intermittent no start and Stop Safely
Now message displayed in the instrument panel cluster (IPC) and/or diagnostic trouble codes (DTC) U0293 and/or
P1A43 in the BECM or in connected vehicle data. A gateway module A (GWM) software concern may be triggering
the no start condition. To correct the condition, follow the Service Procedure to reprogram the GWM software.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
* 2023 F-150
+ Equipped with a hybrid engine
+ At least one of the following conditions:
- Intermittent no start and/or Stop Safely Now message displayed in the IPC
- U0293 and/or P1A43 stored in the BECM or in connected vehicle data

Service Procedure
NOTE: Ask the customer to bring their spare key fob to assist in the Ford Diagnosis and Repair System
(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, universal serial
bus (USB) flash drive variability, and the potential that controller area network (CAN) flashing (software

update via the data link connector [DLC] with FDRS) may be required. It is recommended to connect to the

internet with an ethernet cable and use a USB 3.0/3.1 capable flash drive when performing software updates.

1. Start an FDRS session and navigate to Toolbox tab > Datalogger > body control module (BCM) and select the
BATT_SOC parameter identification (PID). Verify the PID reads 50% or higher. If state of charge (SOC) is less than
50%, charge the battery then navigate back to Toolbox tab > BCM > Reset Battery Monitor Sensor Learned Values
application. Perform the battery monitor sensor (BMS) reset.

(1). If the battery is unable to achieve an 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 recharge 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 center screen or a message on the FDRS saying Part Number Validation Failed or DID Validation Failed.

3. Are there any software updates available for the GWM, sync module (APIM), or telematic control unit module
(TCU)?

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

4. Perform the Module Software Updating Procedures outlined below for the GWM, APIM, and TCU. 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:

> GWM
+ APIM
*TCU

NOTE: If the next update is not showing available, perform a network test and recheck availability.

NOTE: A 32GB or larger universal serial bus (USB) flash drive is required for the GWM, TCU and APIM

software updates. USB 3.0 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 will result 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 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 center display screen:

(1). Turn the ignition off.

(2). Wait for 10 minutes.
(3). Restart the vehicle (key-on vehicle running/ready). The update is still in progress at this time.

NOTE: It may take up to 5 minutes before the center display screen displays Update Successful pop up. After

5 minutes if Update Successful pop up is not shown on the center display screen, remove the USB 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. Once the pop up stating Update Successful appears in the 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.
