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.

Total mileage, value
Measurement range: 0-1,000,000 km
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.

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

Outside temperature, value
Measurement range: -40 to +215 °C
The value indicates the outside temperature when the diagnostic trouble code (DTC) was stored

Power supply position, status
The value indicates the current status of the power supply position when the diagnostic trouble code (DTC) was stored.
