    Terminal No. (Symbol) Terminal Description Condition Specified Condition
    T9-1 (PGND) - Body ground Ground Always Below 1 V
    T9-5 (ACC) - T9-1 (PGND) Power source (ACC) Ignition switch ACC 11 to 14 V
    Ignition switch off Below 1 V
    T9-6 (B+) - T9-1 (PGND) Power source (+B) Ignition switch off 11 to 14 V
    T9-7 (DIS) - Body ground Charging suspension signal For 5 seconds after turning ignition switch from off to ACC*1 4.5 to 6.0 V
    Device being charged Below 1 V
    Charging suspended due to smart key system status*2 4.5 to 6.0 V
    T9-10 (TAIL) - Body ground Illumination signal Taillight off Below 1 V
    Ignition switch off, taillight on 11 to 14 V

    *1: When the ignition switch is turned from off to ACC, the mobile wireless charger cradle assembly monitors the charging suspension signal for 5 seconds. If the charging suspension signal is not 4 V or more for 0.8 seconds or more during monitoring, the mobile wireless charger cradle assembly determines that there is an open in the charging suspension signal line, blinks (pattern 1) the indicator light (amber), and prohibits operation until the ignition switch is turned from off to ACC again.

    *2: For details about conditions when the certification ECU (smart key ECU assembly) sends the charging suspension signal, refer to System Description.
