RM38N0EC _58 Vehicle Interior _111842 POWER OUTLETS (INT) _0525782 WIRELESS CHARGING SYSTEM(for GTMC Made) J

POWER OUTLETS (INT)  WIRELESS CHARGING SYSTEM(for GTMC Made)  Status Signal Circuit  


DESCRIPTION

This circuit sends a charging suspension signal from the certification ECU (smart key ECU assembly) to the mobile wireless charger cradle assembly. Based on this signal, the mobile wireless charger cradle assembly suspends or resumes wireless charging.

HINT:

The wireless charging system uses the same radio wave frequency that is used to perform verification of the electrical key transmitter sub-assembly. Therefore, when the electrical key transmitter sub-assembly verification is being performed, the certification ECU (smart key ECU assembly) sends a charging suspension signal to the wireless charging system to suspend charging.
