WIRELESS CHARGING SYSTEM - Status Signal Circuit |
DESCRIPTION
This circuit sends a charging stop signal from the certification ECU (smart key ECU assembly) to the mobile wireless charger cradle assembly. Based on this signal, the wireless charging system stops the charging operation.- HINT:
- The charging frequency of the wireless charging system overlaps with the electrical wave frequency band that is used when the entry and start system detects the position of the electrical key transmitter sub-assembly. Therefore, when the electrical key transmitter sub-assembly position is being detected, the charging stop signal from the certification ECU (smart key ECU assembly) makes the wireless charging system stop charging.

INSPECTION PROCEDURE
- NOTICE:
- Before replacing the certification ECU (smart key ECU assembly), refer to the service bulletin.
| 1.CHECK MOBILE WIRELESS CHARGER CRADLE ASSEMBLY (DIS) |
Measure the voltage according to the value(s) in the table below.
Text in Illustration*a
| Component with harness connected
(Mobile Wireless Charger Cradle Assembly)
|
- Standard Voltage:
Tester Connection
| Condition
| Specified Condition
|
E150-5 (DIS) - Body ground
| Within 1 second after turning power switch from off to on (ACC)*1
| 4.5 to 6.0 V
|
When charging
| Below 1 V
|
When charging is temporarily stopped by charging stop signal from certification ECU (smart key ECU assembly)*2
| 4.5 to 6.0 V
|
*1: When the power switch is turned from off to on (ACC), the mobile wireless charger cradle assembly checks the charging stop signal for 1 second. If the charging stop signal is not 4 V or higher for 0.8 seconds or more within 1 second continuously, the mobile wireless charger cradle assembly determines that there is an open circuit in the charging stop signal circuit, blinkes the indicator amber (pattern 1), and stops operation until the next time the power switch is turned on (ACC). For the indicator blinking patterns, (Click here)*2: For the certification ECU (smart key ECU assembly) charging stop signal reception conditions, (Click here)- HINT:
- Check with the certification ECU (smart key ECU assembly) connector connected.
