    Terminal No. (Symbol) Wiring Color Terminal Description Condition Specified Condition
    K1-1 (PGND) - Body ground BR - Body ground Ground Always Below 1 Ω
    K1-5 (ACC) - Body ground B - Body ground Power source (ACC) Power switch on (ACC) 11 to 14 V
    Power switch off Below 1 V
    K1-6 (B+) - Body ground L - Body ground Power source (+B) Power switch off 11 to 14 V
    K1-7 (DIS) - Body ground W - Body ground Entry and start system status signal Within 1 second after turning power switch from off to on (ACC)*1 4.5 to 6.0 V
    When charging Below 1 V
    When charging is temporarily stopped by charging stop signal from certification ECU (smart key ECU assembly)*2 4.5 to 6.0 V
    K1-10 (TAIL) - Body ground GR - Body ground Illumination signal Headlight dimmer switch assembly off Below 1 V
    Headlight dimmer switch assembly set to TAIL or HEAD 11 to 14 V

    *1: When the power switch is turned from off to on (ACC), the mobile wireless charger cradle assembly checks the charging stop signal for 1 second. If the charging stop signal is not 4 V or higher for 0.8 seconds or more within 1 second continuously, the mobile wireless charger cradle assembly determines that there is an open circuit in the charging stop signal circuit, blinkes the indicator amber (pattern 1), and stops operation until the next time the power switch is turned on (ACC).
