This bulletin supersedes 21-2123. Reason for update: Incorrect or Incomplete Symptom Model: Ford 2021 Mustang Mach-E Summary This article supersedes TSB 21-2123 to update the Issue and Action. Issue: Some 2021 Mustang Mach-E vehicles built on or before 11-May-2021 may exhibit an inoperative level 2 charger (220/240 volt) at a customer's residence but charging performance operates as intended at a dealership or other locations or inoperative one pedal drive with powertrain malfunction indicator with code P087F and an antilock braking system (ABS) light with diagnostic trouble code (DTC) C0051:67. This may be due to differences in local electrical power grids for the Level 2 charger and/or software in the ABS for one pedal drive and an illuminated ABS lamp.

Labor Times Description Operation No. Time 2021 Mustang Mach-E: Reprogram The Appropriate Modules As Required By The Software Update And Service Procedure (Do Not Use With Any Other Labor Operations) MT212171​ Actual Time​ Repair/Claim Coding Causal Part: 10B689 Condition Code: 04 Service Procedure 1. Connect a battery charger to the 12-volt battery. NOTE: Verify that the negative cable of the charger is installed on a chassis or engine ground, and not the 12-volt battery negative terminal to prevent the battery saver mode from activating on the vehicle. Do not have the vehicle plugged into the high voltage battery charger during programming. This can cause modules to not program correctly; only have the 12-volt battery charger installed. 2. Reprogram the PCM using the latest software level of the appropriate Ford diagnostic scan tool. 3. Check the availability for software updates on the following modules and update as required: (1). Secondary on board control module (SOBDM) (2). Battery energy control module (BECM) (3). Secondary on board control module B (SOBDMB) (4). Secondary on board control module C (SOBDMC) (5). ABS module NOTE: Only one module may be updated at a time.
