Affected Component: ELECTRICAL SYSTEM

Summary
2015-2023 Transit vehicles equipped with 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.
