Manufacturer summary

Original wording in English

TSB: Some 2021 model year Mirai vehicles may exhibit a MIL ON condition with Diagnostic Trouble Code (DTC) P060A47 (Hybrid/EV Battery Energy Control Module Monitoring Processor Watchdog / Safety MCU Failure) present. The Fuel Cell Vehicle (FCV) control computer logic has been modified to reduce the possibility of this condition. Follow the Repair Procedure in this bulletin to address this condition.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
