# Service bulletin TSIB 22\-01

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: 10208761
- Published by NHTSA: 2022\-03\-04
- Manufacturer's number: TSIB 22\-01

## NHTSA's summary

This is an upgrade to Technical Service Information Bulletin TSIB 21\-10 issued in January of 2022 which is specific to buses operating in severe duty and or corrosive environments. These bulletins have been issued to recommend interim inspection procedures required every 6000 miles on specifically equipped motor coaches due to global parts shortages and the subsequent delay in available parts to conduct the corrective actions associated with NHTSA Recall 21V\-748.
