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.
