Description of frozen values

Explanation

Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.
Not all parameters can be read off for all diagnostic trouble codes (DTCs). The parameter values can only be read off where they can provide more information about the prevailing circumstances when the diagnostic trouble code (DTC) was stored.
