Official summary
Some 2022 Transit vehicles built on or before 01-Sep-2022 with halogen lamp assemblies may exhibit a turn signal indicator fast flashing in the instrument cluster panel (IPC) with diagnostic trouble code(s) (DTC) B123A and/or B123B stored in the body control module (BCM). This may be due to a front turn signal lamp socket being internally damaged. To correct this condition, replace the affected front turn lamp socket before replacing the BCM.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
