Service bulletin SSM 51290

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
