SSM 506382022-03-29. Service bulletin. ELECTRICAL SYSTEM. Some 2021 Mustang Mach-E vehicles may exhibit an erroneous diagnostic trouble code (DTC) U2404:92 stored in the GWM after a Ford Power-Up software update was delivered over-the-air (OTA) or the GWM software was updated using the Ford Diagnosis And Repair System (FDRS). This may be due to various software parameters within the GWM. If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the GWM operation, this DTC should be disregarded. This DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability. Ford is developing a software update which will be delivered to the vehicle via a Ford Power-Up GWM update in March 2022 to prevent this DTC from setting erroneously.
TSB 22-21092022-03-29. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. This article supersedes TSB 22-2069 to update the Service Procedure. Some 2021 F-150 and Mustang Mach-E vehicles may exhibit various driver assistance system warning messages or inoperative features and/or diagnostic trouble codes (DTC) U3000:49, U3000:89, U2107:68, C1001:54 and/or C1001:78. DTC B1578:78 may also set after an image processing module A (IPMA) on-demand self test is performed. This may be due to software in the IPMA. To correct the condition, follow the Service Procedure to reprogram the IPMA to the latest level.
TSB 22-21172022-03-29. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT; COMMUNICATION:MANUFACTURER TELEMATICS. Some 2021 Mustang Mach-E and F-150 customers may report experiencing a Ford Power-Up software update failure message via the vehicle display and/or FordPass. In addition, some technicians may experience the inability to update the accessory protocol interface module (APIM) or telematics control unit (TCU) using the Ford Diagnosis and Repair System (FDRS) and Universal Serial Bus (USB) drive. It may also be observed on the PTS - Over The Air (OTA) dashboard that multiple APIM and/or TCU updates have failed, or a no OTA history message is displayed. This may be due to a internal software error. To correct this condition, follow the Service Procedure to recover the APIM/TCU.
TSB 22-21052022-03-22. Service bulletin. ELECTRICAL SYSTEM:ADAS:AUTONOMOUS/SELF DRIVING:SOFTWARE; EQUIPMENT. Some 2021-2022 F-150/Mach-E vehicles equipped with BlueCruise may experience loss of BlueCruise hands-free driving mode availability. This may be due to an expired BlueCruise map file in the gateway module (GWM). To correct the condition, follow the Service Procedure to update the GWM.
SSM 505532022-03-08. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT. Some 2021 F-150/Mustang Mach-E vehicles may display OTA Update Not Successful messages on the vehicle's center touchscreen. Also, when a software update is being performed on the accessory protocol interface module (APIM) using the FDRS, the center touchscreen may not indicate the APIM software is downloading when plugging a USB drive into the vehicle. This may be due to an APIM software concern. Inform customers that Ford is currently working on a solution for this condition that is to be released via the Ford Diagnosis and Repair System (FDRS) in March 2022. Inform the customer that they can continue to drive the vehicle and only need to schedule a follow-up appointment if they are still experiencing the OTA Update Not Successful message in April 2022 or if the APIM is not able to be updated via the FDRS. Monitor OASIS for updates.

To correct the condition, place the steering wheel in the center position so that the driver status monitor camera is visible. Connect the Ford Diagnosis and Repair System (FDRS) and clear the DTCs. Turn the ignition off and wait 10 seconds. Turn the ignition on and wait 1 minute. Using the FDRS, perform the CMR self-test to confirm the codes are cleared.
21B692022-02-17. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY. In all of the affected vehicles, incomplete sealing of certain high voltage battery modules may have occurred during the manufacturing process. An improperly sealed high voltage battery module could result in an electrolyte leak from the suspect battery module(s), resulting in an isolation fault or low battery module voltage condition, which may lead to an interruption of drivability.
TSB 22-20342022-02-16. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 2021 Mustang Mach-E vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0D2A. This may be due to the parameters in the powertrain control module (PCM). To correct the condition, follow the Service Procedure to reprogram various modules starting with the PCM.

ELECTRICAL SYSTEM:SOFTWARE; UNKNOWN OR OTHER. 2021-2022 various Ford and Lincoln vehicles may exhibit an erroneous diagnostic trouble code (DTC) U1A01:93 stored in the telematics control unit (TCU). This may be due to various software parameters within the TCU. If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the TCU operation, clear this DTC and no further repairs are recommended. If the DTC returns after being cleared or if the vehicle exhibits connectivity concerns with the TCU, continue with normal Workshop Manual (WSM) diagnostics. If set erroneously, this DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability. Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) TCU update in July 2022 to prevent this DTC from setting erroneously.
SSM 504442022-02-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; EQUIPMENT. Some 2021 Mustang Mach-E vehicles may exhibit illuminated instrument panel cluster (IPC) backlight with key-off, causing 12V battery drain. To resolve this condition, park the vehicle and close doors, allow vehicle to enter key-off status, wait for the brake indicator to turn off, turn on hazard lights for 3 flashes and turn off. An IPC software update is expected to be delivered to vehicles via an over-the-air (OTA) update in March 2022 to permanently resolve the condition. Let the customer know they can continue to drive the vehicle and advise to connect to their FordPass account to enable OTA delivery.

SSM 502132021-10-29. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM:BODY CONTROL MODULE/BCM; ELECTRICAL SYSTEM:BODY CONTROL MODULE:SOFTWARE. Some 2021 Mustang Mach-E vehicles that have had a body control module (BCM) update may show the Frunk button on their FordPass app. This button is not currently supported and using it will result in a Failure To Open message. Ford is working on an update to the software to activate this button that is expected via over the air (OTA) in late December of 2021. The software will update automatically if Vehicle Connectivity is turned ON. Inform the customer that they can continue to drive the vehicle. Contact the customer in January of 2022 to determine if they received the update. If the customer needs assistance, schedule a follow-up appointment. Monitor OASIS for updates.
21B532021-09-30. Service bulletin. ELECTRICAL SYSTEM.

TSB 21-23072021-09-30. Service bulletin. STRUCTURE:BODY:HATCHBACK/LIFTGATE; ELECTRICAL SYSTEM:INTERIOR LAMPS/BULBS. Some 2021 Mustang Mach-E vehicles built on or before 01-Jul-2021 may experience a water leak into the liftgate. This may be due to water intruding past the seals on the liftgate mounted rear lamp assemblies. To correct the condition, follow the Service Procedure to seal the lamp cavities.
SSM 501512021-09-28. Service bulletin. ELECTRICAL SYSTEM. Some 2020-2021 Explorer/Aviator Hybrids, 2021 Corsair Hybrid, 2021 F-150 PowerBoost, and 2021 Mustang Mach-E vehicles may exhibit a no-start with a Stop Safely Now warning message in the instrument panel cluster (IPC). The vehicle may have one or more of the following DTCs P0A23, P0A6F, P0A72, P0A75, P0A71, P0A74, P0A77, P0DFA, P06B1, P0A47, P1A0E set by the secondary on-board diagnostic module C (SOBDMC) or secondary on-board diagnostic module B (SOBDMB). This may be due to a drop in the 12-volt circuit. These DTCs will often occur at vehicle key-on and may be difficult to reproduce. Before replacement of the SOBDMC or SOBDMB, diagnose any low voltage DTCs (P0562, U3003) in other modules in the 12V system. If low voltage (less than 10V) is observed in these DTCs snapshot, diagnose the 12v system first. Refer to Workshop Manual (WSM), Section 418-00.
