Bulletin Summary
Some coaches equipped with both the SilverLeaf system and a TRC transfer switch (model 40350RVC-40350RVC3) may receive a warning on the SilverLeaf touchscreen that reads âtransfer switch 0-0 failure unknown.â This is a false warning caused by the TRC transfer switch program code.
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.
