    Tech Tips

    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.
