RM3660EC _58 Vehicle Interior _080766 POWER OUTLETS (INT) _0611796 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.

CAUTION / NOTICE / HINT

NOTICE:

Before replacing the certification ECU (smart key ECU assembly), refer to Service Bulletin.


PROCEDURE

1.CHECK MOBILE WIRELESS CHARGER CRADLE ASSEMBLY (DIS TERMINAL)
a.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Condition Specified Condition

*1: When the ignition switch is turned from off to on (ACC), the mobile wireless charger cradle assembly monitors the charging suspension signal.

*2: For details about conditions when the certification ECU (smart key ECU assembly) sends the charging suspension signal, refer to System Description.

2.CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU (SMART KEY ECU ASSEMBLY) - MOBILE WIRELESS CHARGER CRADLE ASSEMBLY)
a.

Disconnect the O174 certification ECU (smart key ECU assembly) connector.


b.

Disconnect the I244 mobile wireless charger cradle assembly connector.


c.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:
Tester Connection Condition Specified Condition
O174-20 (WCSW) - I244-2 (DIS) Always Below 1 Ω
O174-20 (WCSW) or I244-2 (DIS) - Body ground Always 10 kΩ or higher



Result:
Proceed to
OK
