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 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 EDRS 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% SQ, 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 EDRS 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 FRRS saying Part Number Validation Failed or DID Validation Failed.
3. Is there a software update available for any of the following modules?
* GWM
* ARIM
* PCM
* SOBDMC
* BCM
* IPC
(1). Yes - proceed to Step 4
(2). No - this article does not apply.
4. Prepare to update the software for the GWM, APIM, and TCU.
(1). A 32GB or larger USB flash drive is required for APIM, TCU, and GWM software updates. USB 3.2 Gen 2 or
higher is recommended for faster file transfer on both the computer port and the USB drive.
(2). 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.
(3). 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.
(4). De-selecting Quick Format is not necessary and results in a lengthier operation.
5. Using the FDRS, begin module programming by selecting the SW Updates tab. Follow all on-screen instructions
carefully.

6. When prompted, connect the USB flash drive to the FDRS.
7. When prompted by the FDRS, safely remove/eject the USB flash drive from the FDRS. Start the vehicle (KOQER)
then connect the USB flash drive 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 with software update.
8. When the vehicle's center display screen prompts to restart the vehicle:
(1). Turn the vehicle OFF.
(2). Wait 10 minutes.
(3). Restart the vehicle (key-on vehicle running). The update is still in process at this time.
9. Follow FDRS on-screen prompts to complete the update.
NOTE: It may take up to 5 minutes before "Update Successful" appears in the vehicle's center display
screen. After 5 minutes if "Update Successful" pop-up is not shown on the center display screen, remove the
USB flash drive and select YES on the FDRS prompt stating “Was The USB Update Successful” ( FDRS
verifies if the module software update was successfully installed on the module).
10. Perform the software update for the GWM. Follow all update screens. If there is no GWM software update
available, proceed to Step 14.
(1). Follow the center display screen prompts.
(2). Follow EDRS prompts to complete the GWM programming.
+ 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.
(3). Perform a network test using the FDRS scan tool.
(4). Proceed to Step 11.
11. Perform the software update for the APIM. Follow all update screens. If there is no APIM software update
available, proceed to Step 15.
(1). Follow the center display screen prompts.
(2). Follow EDRS prompts to complete the APIM programming.
* 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.
(3). Perform a network test using the FDRS scan tool.
(4). Proceed to Step 12.
12. Perform the software update for the TCU. Follow all update screens. If there is no TCU software update available,
proceed to Step 16.
(1). Follow the center display screen prompts.
(2). Follow EDRS prompts to complete the TCU programming.
* 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.
(3). Perform a network test using the FDRS scan tool.
(4). Proceed to Step 13.
