Error #18 in CAN-data from inverter

Hello,

We are logging error codes from the inverter in a Tesla SDU. We get an numeric value of 18 over CAN from the inverter. We can't find error code number 18 on the wiki: https://openinverter.org/wiki/Errors

Car is running fine and a restart of the inverter clears the error. The error occurs rarely totaly random when we drive the car, maybe every 10 drive cycle.

Error code is mapped like this to CAN:

Any one knowing of undocumented errorcodes above number 17?

Hi!
The table wasn't maintained. It is in there now and means motor overheat
