   Standard Voltage

   Tester Connection	Condition	Specified Condition
   D118-10 (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

   HINT: 

   • *1: The wireless charger cradle 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 wireless charger cradle 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. Refer to SYSTEM DESCRIPTION .

1. Disconnect the D118 mobile wireless charger cradle assembly connector.
2. Disconnect the D64 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
   D118-10 (DIS) - D64-7 (ASEL)	Always	Below 1 Ω
   D118-10 (DIS) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   4
