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). 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

30-feed
Measurement range: 0 - 50V
The value indicates the power supply to the Infotainment control module (ICM) when the diagnostic trouble code was stored.

5V supply
Measurement range: 0 - 10V
Normal range: 4.5 - 5.5V
The value indicates the internal power supply to the Infotainment control module (ICM) when the diagnostic trouble code was stored

Display voltage
Measurement range: 0 - 600V
Normal value: 40 - 80V
The value indicates the voltage to the display in the Infotainment control module (ICM) when the diagnostic trouble code was stored.

Ring break On-board diagnostic system (OBD system)
Indicates the status of the most recent Ring break diagnostic.
- OK = There are no faults in the MOST network
- Poor = The infotainment control module (ICM) receives a signal on the MOST network but cannot decode it
- Pos 0 - 8 = An open-circuit has been detected in the specified position in the network.

MOST locked
The status indicates whether the MOST network is closed and communication possible.
