Description Of Frozen Values, HLDF

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 out for all diagnostic trouble codes. The parameter values can only be read if they can provide additional information on the prevailing conditions when the code was generated.

Total mileage, value
Measurement range: 0-1,000,000 km
The value indicates the vehicle's total mileage when the Diagnostic Trouble Code (DTC) was generated.

MECU power supply, value
Measurement range: 0-63 V
Normal range: 12.0-14.5 V
The value indicates the power supply to the central electronic module (CEM) when the diagnostic trouble code was generated.

Passenger compartment temperature, value
Measurement range: -40 till +215 °C
The value indicates the passenger compartment temperature when the diagnostic trouble code was generated.

Outside temperature, value
Measurement range: -40 till +215 °C
The value indicates the outside temperature when the diagnostic trouble code was generated.

Power supply mode, status
The value indicates the status of the power supply mode when the diagnostic trouble code was generated.

Power supply, HLDF, value
Measurement range: 6-20 V
Indicates the power supply to the high level display front (HLDF).
The normal value when the alternator is charging: 13.0-14.5 V.

Internal temperature, value
Measurement range: -40 to 120 ˚C.
Indicates the internal temperature of the high level display front (HLDF).

Counter, screen activation, value
Indicates how many times the high level display front (HLDF) has been activated.

Operating time, HLDF, value
Indicates the number of hours the high level display front (HLDF) has been operating.
