    Special Service Campaign H0E
    2016-2017 Model Year Mirai Fuel Cell System Updates

    Condition:
    Under unique driving conditions, such as if the accelerator pedal is depressed to the wide open throttle position after driving on a long descent while using cruise control, there is a possibility that a warning light will illuminate, a message will be displayed on the instrument panel, and the fuel cell system will stop running. If the fuel cell system stops running, electric power steering and the brakes will function normally. The fuel cell system can be restarted after the vehicle is stopped.

    Also, if the fuel cell system is turned on immediately after refueling, the fuel cell control module may improperly determine that the vehicle is still being refueled and turn off the fuel cell system, also disabling the electric power assisted steering. The vehicle can then be restarted after this occurs.

    Remedy:
    The fuel cell system software in the fuel cell boost control module and the fuel cell control module will be updated at NO CHARGE.

    Covered Vehicles:
    There are approximately 1,200 vehicles covered by this Special Service Campaign.

    Owner Letter Mailing Date:
    Toyota will notify owners in late March 2017
