WIRELESS CHARGING SYSTEM Status Signal Circuit

DESCRIPTION

This circuit sends a smart key system status signal from the certification ECU (smart key ECU assembly) to the upper console panel sub-assembly. Based on this signal, the upper console panel sub-assembly suspends or resumes wireless charging.

INSPECTION PROCEDURE

Note

Before replacing the certification ECU (smart key ECU assembly), refer to the Registration ( Click here).

PROCEDURE


  1. INSPECT UPPER CONSOLE PANEL SUB-ASSEMBLY


    1. A01I1Q7E02
      Text in Illustration
      *a

      Component with harness connected

      (Upper Console Panel Sub-assembly)

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      I179-10 (DIS) - Body ground For 1500 ms after turning engine switch from off to on (IG)*1 4.4 to 6.5 V
      Being charged Below 1 V
      Charging suspended due to smart key system status*2 4.4 to 6.5 V

      Tech Tips


      • *1: The upper console panel sub-assembly checks the status signal for 1500 ms when the engine switch is turned from off to on (IG). If a status signal voltage of less than 1 V continues for 400 ms or more during the check, the upper console panel sub-assembly judges that the status signal is interrupted, blinks the indicators and stops the operation until the engine switch is turned off then on (IG) again.

      • *2: For the status of the smart key system when charging is stopped temporarily, refer to System Description Click here.

  2. CHECK HARNESS AND CONNECTOR (UPPER CONSOLE PANEL SUB-ASSEMBLY - CERTIFICATION ECU (SMART KEY ECU ASSEMBLY))


    1. Disconnect the I179 upper console panel sub-assembly connector.

    2. Disconnect the O1 certification ECU (smart key ECU assembly) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      I179-10 (DIS) - O1-7 (ASEL) Always Below 1 Ω
      I179-10 (DIS) - Body ground Always 10 kΩ or higher
