Description Of Frozen Values, Central Electronic Module (CEM)

Description of frozen values, central electronic module (CEM)

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). They can only be read off where they can provide more information about the prevailing circumstances when the diagnostic trouble code (DTC) was stored.

Battery voltage, value
Measurement range: 5 - 30 V.
Normal value when the generator (GEN) is charging: 13.0 - 14.5 V.

Distance, value
Measurement range: 0 - 1048575 km.
The value indicates the total mileage of the car at the time the diagnostic trouble code (DTC) was stored.

Passenger compartment temperature, value
Measurement range: -60 - 192 °C.
The value indicates the passenger compartment temperature of the car at the time the diagnostic trouble code (DTC) was stored.

Outside temperature, value
Measurement range: -128 - 124 °C.
The value indicates the outside temperature at the time the diagnostic trouble code (DTC) was stored.

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

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