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.

Engine started, 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.

Outside temperature, value
The value indicates the outside temperature at the time the diagnostic trouble code (DTC) was stored.
Measurement range: -128 °C to +127.75 °C

Passenger compartment temperature, value
The value indicates the passenger compartment temperature at the time the diagnostic trouble code (DTC) was stored.
Measurement range: -60 °C to +195 °C.

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

CEM system voltage, value
The value indicates the supply voltage to the central electronic module (CEM) when the diagnostic trouble code (DTC) was stored.
Measurement range: 5 - 30 V.
Normal range: 12.0 - 14.5 V.

Oil temperature, value
The value indicates the oil temperature in the Active on Demand Coupling when the diagnostic trouble code (DTC) was stored.
Measurement range: -128 °C to +127 °C
Normal range: 50 - 60 °C.

Oil pressure, value
The value indicates the oil pressure in the Active on Demand Coupling when the diagnostic trouble code (DTC) was stored.
Measurement range: 0 - 4 Mpa.
Normal range: 0.4 -2.0 Mpa.

Power supply control module, value
The value indicates the power supply to the differential electronic module (DEM) when the diagnostic trouble code (DTC) was stored.
Measurement range: 0 - 24 V.
Normal range: 12.0 - 14.5 V.

Power supply solenoid, value
The value indicates the current through the control solenoid when the diagnostic trouble code (DTC) was stored.
Measurement range: 0 - 4095 mA.

Power supply pump motor, value
The value indicates the current through the hydraulic feed pump when the diagnostic trouble code (DTC) was stored.
Measurement range: 0 - 8191 mA.
