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.

Parameters, value

Total mileage
Measurement range: 0 - 1.000.000 km.
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.

Battery voltage, central electronic module (CEM)
Measurement range 0 - 63 V.
Normal range: 12.0 - 14.5 V.
The value indicates the supply voltage to the central electronic module (CEM) when the diagnostic trouble code (DTC) was stored.

Passenger compartment temperature
Measurement range: -40 to +215 °C.
The value indicates the passenger compartment temperature when the diagnostic trouble code (DTC) was stored.

Engine running
The status displays whether the engine was running when the diagnostic trouble code (DTC) was stored.
Yes = the engine was running
No = the engine was not running
