Official summary
2015-2021 Transit vehicles equipped with dual rear wheels (DRW) have a high mount rear marker lamp that does not illuminate with the stop lamps. This lamp assembly may appear to be a stop lamp but is intended to illuminate with the parking lamps only. This information is available in Workshop Manual Section 417-01. The JDDAB feature code description found under OASIS additional information is common between single rear wheel and DRW vehicles, and incorrectly reflects stop functionality when applied to DRW units.
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.
