# Service bulletin PB1779

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 11023934
- Published by NHTSA: 2025\-10\-06
- Manufacturer's number: PB1779
- Manufacturer's date: 2025\-09\-22
- NHTSA component: UNKNOWN OR OTHER

## NHTSA's summary

Four parts are involved because they correspond to blue and red caps, which will no longer be available due to the supplier discontinuing their production. We will be transitioning to black caps over time and will retain the same part number, resulting in a mixed inventory. The new black caps are fully compatible with all existing products and will not impact on the performance or functionality of your equipment.
