Description Of Frozen Values, IAM

Description of frozen values

Explanation
All parameters described do not need to be implemented in the Integrated Audio Module (IAM), this varies from system to system.
Frozen values are parameter values stored when a Diagnostic Trouble Code (DTC) is generated.

Battery voltage, Central Electronic Module (CEM)
Measurement range: 5-30 V.
The normal value when the alternator is charging: 13.0-14.5 V.
The value indicates the voltage to the Central Electronic Module (CEM).

Mileage, value
Measurement range: 0-1048575 km.
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.

Passenger compartment temperature, value
Measurement range: -60 to +195 °C.
The value indicates passenger compartment temperature when the Diagnostic Trouble Code (DTC) was generated.

Outside temperature, value
Measurement range: -128 to +127.75 °C.
The value indicates outside temperature when the Diagnostic Trouble Code (DTC) was generated.

Engine running, status
The status indicates whether the engine was running when the Diagnostic Trouble Code (DTC) was generated.
No = the engine was not running
Yes = the engine was running
