Service Procedure
NOTE: The time required to complete this procedure varies depending on several factors including the number of module software updates
required, available internet bandwidth, USB flash drive variability, and the potential that controller area network (CAN) flashing (software update
via the data link connector [DLC] with Ford Diagnosis and Repair System [FDRS]) may be required. Connect to the internet with an ethernet
cable and use a USB 3.0 or higher 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 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 state of charge while performing a software update
to any module may result in a repeat Restart Required message in the vehicle 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 enhanced central gateway (ECG), APIM and/or telematics 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 for further diagnostics.

4. Perform the Module Software Updating Procedures outlined below for the following modules: ECG, APIM and/or 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. 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: A 32GB or larger USB flash drive is required for ECG, APIM, and TCU 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 software updates
in the order below:

NOTE: All 3 modules must be updated.

NOTE: Depending on the current software level of the modules, all the following updates may not be required.

(1). ECU (first)
(2). APIM (second)
(3). TCU (last)

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). The update is still in process 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.
