*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.
