Description of Frozen Values, TRM

Description of frozen values

Explanation
Not all the parameters described need to be implemented in the trailer module (TRM). This varies from system to system.
Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.

Battery voltage central electronic module (CEM), value
Measurement range: 5 - 30 V.
Normal value when the generator (GEN) is charging: 13.0 -14.5 V.
The value indicates the voltage at the central electronic module (CEM).

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: -40 - 80 °C.
The value indicates the passenger compartment temperature 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
