Description of frozen values

Explanation
Frozen values are parameter values that are stored when a diagnostic trouble code is generated. Not all parameters can be read out for all diagnostic trouble codes. The parameter values can only be read if they can provide additional information on the prevailing conditions when the code was generated.

Engine running
The status denotes whether the engine was running or not when the diagnostic trouble code was generated.

Global time
The value displays the time that has passed since the diagnostic trouble code (DTC) was stored.

Passenger compartment temperature, value
Measurement range: -40 till +80 °C
The value indicates the passenger compartment temperature when the diagnostic trouble code was generated.

Outside temperature, value
Measurement range: -40 till +80 °C
The value indicates the outside temperature when the diagnostic trouble code was generated.

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

Total mileage
Measurement range: 0-1000000 km.
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.
