Refer to DTC CHECK / CLEAR [03/2023 - ] 

HINT: 

If the Freeze Frame Data item "AC Input Voltage for Monitoring" shows 270 V or more, there is a possibility that the charging voltage was higher than standard voltage, causing a DTC to be output. When performing a reproduction test, normal charge the vehicle at the standard voltage, then check for DTCs.

Refer to DTC CHECK / CLEAR [03/2023 - ] 

HINT: 

• Make sure to save freeze frame data because the data is necessary for performing simulation tests.
• For the hybrid control system, there are many DTCs, many of which can be stored due to a single malfunction. As a result, in some of the diagnosis procedures an instruction is provided to check for other DTCs. By following the diagnosis path based on the combination of output DTCs, it is possible to narrow down the problem early and avoid unnecessary diagnosis.
