RM36D0EC _58 Vehicle Interior _083105 POWER OUTLETS (INT) _0584671 WIRELESS CHARGING SYSTEM J

POWER OUTLETS (INT)  WIRELESS CHARGING SYSTEM  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.
