CAUSE ANALYSIS (USER / ENVIRONMENT / EXTERNAL POWER SOURCE/CHARGING STAND RELATED CAUSE) 

1. Perform cause analysis in the order of "User Related Cause", "Environment Related Cause" and "External Power Source/Charging Stand Related Cause" categories as specified in the following tables below.
   USER RELATED CAUSE
   
   

   Possible Cause	Action to be Taken
   Scheduled charging time is set	Interview customer and provide instruction on usage. Refer to PROBLEM SYMPTOMS TABLE [12/2023 - ] Explain to the customer that if the charging connector is connected when the charge schedule is set, the charging indicator (EV charger lid indicator) will blink for a few seconds and then turn off. Explain to the customer that plug-in charging will not start immediately after connecting the charging connector if the charge schedule is set. (Explain to the customer that plug-in charging can be started immediately if all of the charge schedules are canceled or if Charge Now is turned on.) Explain to the customer that if they want to perform charging immediately, if a scheduled charging time is set, they must select "Charge Now" on the multi-information display.
   Charging station was used improperly	Confirm how to properly use the charging station with user's manual or instructions etc.
   Charging connector was not securely connected to charging inlet	Interview customer and provide instruction on usage. Refer to PROBLEM SYMPTOMS TABLE [12/2023 - ] Explain to the customer that the charging connector should be fully inserted into the charging inlet.
   Plug-in charging was attempted when HV battery was fully charged	Explain to the customer that if the charging connector is connected to the vehicle when the HV supply battery assembly is fully charged, the EV charger lid indicator (EV charger lid indicator assembly) will illuminate (when timer charging is off) or blink (when timer charging is operating) for several seconds and then turn off and AC charging will not start.

   ENVIRONMENT RELATED CAUSE
   
   

   Possible Cause	Action to be Taken
   Plug-in charging was suspended due to power outage, circuit breaker operation, etc.	Interview customer and provide instruction on usage. Refer to PROBLEM SYMPTOMS TABLE [12/2023 - ] Explain to the customer that the plug-in charging was suspended due to power outage, circuit breaker operation, etc.

   EXTERNAL POWER SOURCE/CHARGING STAND RELATED CAUSE
   
   

   Possible Cause	Action to be Taken
   Charging was suspended by charging station or charging station was incompatible	Interview customer and check the charging station. Refer to PROBLEM SYMPTOMS TABLE [12/2023 - ] Explain to the customer that plug-in charging may not start due to a power management function or charging control function of the charging station. Also, charging may not be performed if the charging station is incompatible. (Check the charging station specifications provided by the manufacturer.) Explain to the customer that depending on the charging station, charging may not begin if the charging timer is set.
   Charging was suspended due to abnormal electrical outlet voltage	Interview customer and check the electrical outlet. Refer to PROBLEM SYMPTOMS TABLE [12/2023 - ] If charging does not begin due to an abnormal electrical outlet voltage or an inappropriate ground wire connection, the electrical outlet should be checked by a qualified tradesperson.

2. Take appropriate action in accordance with the result of the cause analysis.
