Vehicle Communication Information, Central Electronic Module (CEM)

Description of frozen values, central electronic module (CEM)

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

Battery voltage, value
Measurement range: 0-12 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: -60-195 °C.
The combined instrument panel obtains the value via the control area network (CAN).

Outside temperature, value
Measurement range: -128-127.75 °C.
The combined instrument panel obtains the value via the control area network (CAN).

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.
