*1: When the engine switch is turned from off to on (ACC), the mobile wireless charger cradle assembly (front console box insert sub-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 (front console box insert sub-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 engine switch is turned from off to on (ACC) again.
*2: For details about conditions when the certification ECU (smart key ECU assembly) sends the charging suspension signal, refer to System Description.
