- Summary
- 16078 -Service Update Bulletin. The light output of the forward Park/Position lamps is above design intent. The software in the Park/Position lamp?s electronic control unit was programmed incorrectly, leading to the Park/Position lamp?s electronic control unit to misinterpret the signals from the vehicle?s body control module. This results in higher-than-expected light output. Install right and left side in-line headlamp jumper harnesses.
