V4D - Separated Stop/Turn Issue
Due a change that was implemented for the 2017 model year that altered wiring, the Express/Savana Cutaways do not function as intended. They function as combined stop/turn rather than separated stop and turn.
Production Vehicle Update: Vehicles built after September 30th 2016 have a new calibration that allow/enables the V4D separated Stop/Turn signals, however this update does not address the ability to have both trailer lighting and separated signals...efforts to provide both functions are still underway.
UPDATE: the Service/Field fix is NOW AVAILABLE refer to UI Bulletin #135
