This article supersedes TSB 22-2263 to update the Title, Issue, Action, Service Procedure, and Part List. Some 2019-2021 Transit vehicles built on or before 11-Feb-2021 may experience a front seat cushion sagging. The vehicle may also exhibit an illuminated air bag warning indicator with diagnostic trouble codes (DTCs) B1408, B1405, B1407, B0001 and/or B0010 stored in the restraints control module (RCM). To correct this condition, follow the Service Procedure to replace the suspension mat assembly and install additional webbing strap assemblies to the seat frame.
