RM38T0EC _58 Vehicle Interior _112290 POWER OUTLETS (INT) _0606057 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.

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 Component with harness connected
(Mobile Wireless Charger Cradle Assembly)


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

Standard Voltage:
Tester Connection Condition Specified Condition
I287-2 (DIS) - Body ground For 2 seconds after turning ignition switch from off to ACC*1 4.5 to 6.0 V
Device being charged Below 1 V
Charging suspended due to entry and start system status*2 4.5 to 6.0 V


*1: When the ignition switch is turned from off to ACC, the mobile wireless charger cradle assembly monitors the charging suspension signal for 2 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 2) the indicator light (red), 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.
