Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
