Service bulletin MCI Field Notes

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.

NHTSA's summary

This Service Advisory informs affected owners of model year 2018 J4500 model coaches equipped with the battery charger/inverter (P/N 07-08-7957 or 07-08-9634) or battery charger (P/N 07-08-2627), that the programming prevents the starter from cranking with the onboard charger plugged into a wayside 110V and gives a warning message of "Starter Fault". MCI plans to revise the coach Operator's Manual to include this information and in more detail in the next update.
