Exterior Charge Status Indicator Not Illuminating Blue Charging Segments °' December
After An OTA Update
Model:
Ford
2021-2022 Mustang Mach-E
Issue: Some 2021-2022 Mach-E vehicles may experience an exterior charge status indicator not illuminating the
blue charging segments after an over the air (OTA) update. This may be due to the software in the SYNC module
(APIM). To correct the condition, follow the Service Procedure steps to reprogram the APIM.
NOTE: The APIM software update that addresses the symptom listed in this bulletin may have been sent via
Ford Power-Up software updates delivered over- the-air (OTA) to connected vehicles that have automatic
updates enabled through the center display screen. Enter the vehicle identification number (VIN) in
Professional Technician System (PTS) and check the OTA Dashboard under the Connected Vehicle tab for
OTA update history. If an update to the APIM 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 steps to correct the condition on vehicles that meet all of the following criteria:
* 2021-2022 Mustang Mach-E
+ Exterior charge status indicator not illuminating the blue charging segments after an over the air (OTA)

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 varies 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 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 recharge 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 gateway way module (GWM)?

(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, telematics control unit module
(TCU), APIM and instrument panel cluster (IPC). 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 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.

5. For 2021 vehicles only, perform the IPMA Software Updating Procedure. When performing the IPMA software
update additional modules will receive software updates. Depending on vehicle features, the coordinated software
update includes the IPMA, power steering control module (PSCM), cruise control module (CCM) and/or camera
module - rear (CMR).

(1). Reprogram the IPMA using the latest FDRS software level. Follow all on-screen instructions carefully to
complete all coordinated module software updates.

(2). Perform the FDRS Image Processing Module A (IPMA) Alignment procedure.

(3). Perform the appropriate FDRS camera alignment procedure.

(4). For vehicles equipped with 360 degree cameras, perform the IPMA - 360 Degree View Camera Alignment
procedure.

(5). For vehicles not equipped with 360 degree cameras, perform the IPMA - Pro Trailer Backup Assist Camera
Alignment procedure. This procedure should be performed on all vehicles without 360 degree cameras, even if
the vehicle is not equipped with Pro Trailer Backing Assist™ (PTBA).

6. For 2021 vehicles only, perform the Module Software Updating Procedures outlined below for the GWM, TCU and
APIM again.

Module Software Updating Procedure

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

- GWM
-TCU
-APIM
- IPC

NOTE: A 32GB or larger USB flash drive is required for software updates. 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 key on
engine running (KOER). Connect the USB flash drive to the media hub to install the software update. The update
automatically starts 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 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 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 GWM, TCU, APIM and IPC software update.
