This is a big one, a dedicated TSB for HVBJB replacement. First of all, I'm glad Ford released this TSB to consolidate the information in the service manual, and make it easier for dealers to properly repair vehicles with HVBJB issues. We were seeing some confusion over the proper response to certain DTCs and correct part numbers, this TSB should clarify that moving forward. This also adds the requirement to update the powertrain software to latest, which was skipped in some repairs.

Illuminated MIL And/Or Stop Safely Now Message, Low Or Discharged 12V Battery And/Or Various DTCs - Built On Or Before 28-May-2022
01 August 2022
Issue: Some 2021-2022 Mustang Mach-E vehicles built on or before 28-May-2022 may exhibit an illuminated malfunction indicator lamp (MIL) and/or display a Stop Safely Now message in the instrument panel cluster (IPC) with diagnostic trouble codes (DTCs) P0563, P0ADA, P0ADE, P0AA1, P0AA4, P0AA5, P0AA2, P0D10, P0D0F, and/or P0C78 stored in battery energy control module (BECM) or a low/discharged 12V battery with P0DA8 and/or P1A10 in the secondary onboard diagnostic module-C (SOBDMC). This may be due to the high voltage battery junction box (HVBJB). To correct the condition, follow the Service Procedure to replace the HVBJB and reprogram the BECM.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
Unit of Issue refers to the number of individual pieces included in a service part number package.
Piece Quantity refers to the total number of individual pieces required to repair the vehicle.
As Needed indicates the amount of the part may vary and/or is not a whole number. Parts can be billed out as non-whole numbers, including less than 1.
Parts To Inspect And Replace Only If Necessary
Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Emissions Warranty/Service Part Warranty (SPW)/Special Service Part (SSP)/Extended Service Plan (ESP) coverage. Limits/policies/prior approvals are not altered by a TSB. NVLW/Emissions Warranty/SPW/SSP/ESP coverage limits are determined by the identified causal part and verified using the OASIS part coverage tool.
1. Replace the HVBJB. Refer to Workshop Manual (WSM), Section 414-03A, Removal and installation.
2. Reprogram the BECM to latest software available. The BECM is part of the powertrain coordinated flash.
(1). Connect a battery charger to the 12-volt battery.
NOTE: To prevent the battery saver mode from activating on the vehicle, verify that the negative cable of the charger is installed on a chassis or engine ground, and not the 12-volt battery negative terminal. Do not plug the vehicle into the high voltage battery charger during programming, this can cause modules to not program correctly. Only use the 12-volt battery charger during programming.
3. Reprogram the PCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool.
4. Check the availability of software updates on the following modules and update as required:
