Tech Tips

The details of a DTC can be checked by using the DTC Sub Code of the freeze frame data that was recorded when the DTC was output.

DTC Sub Code	Detail
"11"	Protection Relay FET Temperature1 is continuously 120°C (248°F) or less for 1 second
"12"	Protection Relay FET Temperature1 is continuously -40°C (-40°F) or less and Protection Relay FET Temperature2 is continuously 0°C (32°F) or more for 60 seconds
"13"	Protection Relay FET Temperature2 is continuously 120°C (248°F) or more for 1 second
"14"	Protection Relay FET Temperature2 is continuously -40°C (-40°F) or less and Protection Relay FET Temperature1 is continuously 0°C (32°F) or more for 60 seconds
"15"	Difference between Protection Relay FET Temperature1 and Protection Relay FET Temperature2 continuously exceeds the threshold for 1 second
